Template:Period color, which color set should we use?
There are many ways to use which color for what piece of the geologic time scale. Many users/Wikipedias disagree about which color set to use then started edit warring and this ends up with a protection of Template:period color. Older discussions about this exact topic had no agreement and 1 admin edited the template using the color set he wanted. One of the discussions ended up off topic because the links linked to the jpg links and the users started arguing about jpg vs pdfs files. I hope this doesn't happen here so leave the links on this page. A complete list of color sets is shown above. 107.3.117.228 (talk) 18:34 27 October 2013 (UTC) 2:34pm 10/27/2013 EDT.


 * I'm struggling to follow the chain of thought here; IIRC previous discussions on this page concluded an active preference against USGS colours (which I have reiterated my preference against in the above table), and for the ICS colours. However, subsequent discussion seems to have degenerated into argument over what the ICS colours exactly were in terms of RGB. The above table seems to convolve these two issues pretty badly. As I interpret it, all of the entries 2-6 are supposed to be ICS colours, but differ from each other. I note Dr Ogg's colours are definitively not the ICS 2013 tones on my monitor; I have no way of assessing User:Alnagov's version or the Hungarian versions as they are just RGB codes and aren't displayed. My strong preference is for the actual 2013 ICS colours, and it really shouldn't be beyond us as a group of rational people to agree what these colours actually are. DanHobley (talk) 19:07, 31 October 2013 (UTC)


 * If one looks at the PDF version of the chart and converts to Postscript, it can be seen that the chart was produced in Illustrator and that the colors are specified in CMYK space using the setcmykcolor operator. So one could extract those CMYK values and convert to RGB, or simply take the JPEG version into Gimp and extract the apparent RGB values using the eye dropper. I suspect the latter was done for the Hungarian values, but I haven't checked them. If we are going to be using these colors, we should probably cite the paper in which the chart was presented, at . As for which color set to use, I have no strong preference. --Mark viking (talk) 20:29, 31 October 2013 (UTC)


 * User:Mark viking if you have no strong preference the default one would be Dr Oggs color set. User:DanHobley The places where I got the chain/refs is now visible as invisible comments and you should tell your geology neighbors about this then comment+vote, or I move this discussion to the village pump. Plus the one you think is the worst should be a invisible comment and put your vote in the one you support. To assess Hungarian codes please see the Hungarian version of the Geologic time scale article I'll put a notice over there in the miscellaneous form and some geology editors I know/find/see due to a long wait for the 1st reply. 107.3.117.228 (talk) 13:40 2 November 2013 (UTC) 8:40am 11/03/2013 EST.

Dune the primary topic?`
Why should "dune" meet significance and popularity criteria enough to be primary? I did propose long ago, but that was a failure. Why can't "dune" be equal to the novel or the film called Dune? --George Ho (talk) 07:42, 22 November 2013 (UTC)
 * well the book got its name from the geographic feature and the movie from the book. Only for SF fans will they think of the book first. The book and movie will fade in importance over time, leaving the sand dune without rival. Graeme Bartlett (talk) 11:34, 22 November 2013 (UTC)
 * Same reason that Avatar is the Hindu concept, and not the James Cameron film. There are topics made primary by popularity, and others where it is more inherently primary. Chris857 (talk) 14:50, 22 November 2013 (UTC)
 * I did propose that dabpage be primary, but many opposed. The sand land, the novel and the film look equally popular. Yet you are saying that Dune will fade into oblivion for the next 10 to 50 years? George Ho (talk) 20:18, 22 November 2013 (UTC)
 * I think it will fade, even though I have read several of the series. Perhaps it won't be oblivion, but just more obscure. Think of the Foundation series was popular but now less so. I enjoyed Earth (Brin novel), but we won't retarget Earth.  2001 should be about the year, but it could have been about the film or book in the previous millennium.  While the film is showing you might get more people wanting to read about that, but it was not really that huge that it would take over the primary topic on any permanent basis. Graeme Bartlett (talk) 21:41, 22 November 2013 (UTC)
 * Of the two main reasons for choosing a primary topic if it is "highly likely—much more likely than any other topic, and more likely than all the other topics combined—to be the topic sought when a reader searches for that term." The numbers you provided show that none of the choices fit this criterion. That leaves "long-term significance". RockMagnetist (talk) 22:15, 22 November 2013 (UTC)
 * Some sand land is more notable and well-valuable than the novel and the film? George Ho (talk) 22:56, 22 November 2013 (UTC)
 * I can't believe I need to argue this, but here goes: Deserts cover one fifth of the Earth's surface, and more than one billion people live in desert regions. Sand dunes account for 1/10 of that area (see this National Geographic article). That's about 3 million square kilometers, the size of India. The novel was published in 1965; the English word entered the language about 1790, but God knows when the first word for dune was coined. RockMagnetist (talk) 23:44, 22 November 2013 (UTC)
 * As for the usual measure of notability in Wikipedia, mention by reliable sources, consider this: If I search Google Scholar for "dune", I get 331,000 hits. If I search "dune -herbert -novel -movie", I get 311,000 results, so the novel and movie account for about 6% of the hits. If I do the same in Google Books, where you'd expect that the novel would have an advantage, the results are 5,410,000 and 4,990,000 - about 8% difference.

Deformation zones
I don't know too much about this topic but should be an article about deformation zones? It just came to my mind since I am planning to rewrite/expand an article about a deformation zone.  Volcano guy  21:18, 28 November 2013 (UTC)


 * What is the context, deformation zones can be on all sorts of scales? Mikenorton (talk) 22:19, 28 November 2013 (UTC)
 * Well it is definitely used to describe fault structures because the article I am planning to rewrite/expand (Net Lake-Vermilion Lake Deformation Zone) is a fault structure. But I am not sure what else "deformation zone" refers to.  Volcano guy  22:34, 28 November 2013 (UTC)
 * I think there should be an article on deformation zone. But don't just copy a dictionary definition, recently we have had to clean up some articles that copied other people's work! Graeme Bartlett (talk) 10:05, 29 November 2013 (UTC)


 * We'll need to cover "deformed zone", "deformed belt" and "disturbance" as well (there are probably others that I can't think of right now). Mikenorton (talk) 20:13, 29 November 2013 (UTC)
 * Deformation_(geology) redirects to deformation engineering - if it was to become a stand alone article based on splitting out content from that I'd be thinking it might need/want to include reference to Fold (geology), Shear (geology) and Orogenic belt and maybe Metamorphism, Dome (geology), anticline, syncline hmmm I'll stop spamming article links, I could go on, when you've finished put a link to the article here and I'll drop by and either link these terms or populate a 'see also' section.EdwardLane (talk) 21:20, 1 December 2013 (UTC)
 * There's nothing special about deformation in geology, apart from it affecting rocks of course. We currently have fault (geology), shear zone and fold and thrust belt, all of which fit within the concept of a deformation zone - @Graeme no worries about just a definition - I can't actually find one, it's a bit of a woolly concept, which makes it more difficult to write an article.

Wikipedia talk:Articles for creation/Franklinphilite
Dear Geologists: This submission at Afc has some references. but they are not online. Is this a notable subject, and are these reliable sources? &mdash;Anne Delong (talk) 04:39, 10 December 2013 (UTC)
 * Refs 1 and 3 are available online. I don't believe the other two are:
 * (1) [Franklinphilite, Handbook of Mineralogy] http://www.handbookofmineralogy.org/pdfs/franklinphilite.pdf‎
 * (3) [Lennilenapeite, The Mg-Analogue Of Stilpnomelane...] http://rruff.info/doclib/cm/vol22/CM22_259.pdf
 * I'll let someone more involved in the project also chime in, but I would conside the four sources as reliable. Also, the article (at least once it hits mainspace) really ought to have Infobox mineral. Chris857 (talk) 14:24, 10 December 2013 (UTC)
 * Thanks, Chris857. Since it's in mineralogy books, it must be a real mineral, so I will accept the article and add an infobox request. &mdash;Anne Delong (talk) 15:13, 10 December 2013 (UTC)

Missing articles
Editor User:Valich created and contributed to a 168 articles that are under review at Contributor copyright investigations/20130908. The review began on 8 September 2013 and continues. A large number of these articles are under the scope of this project, and some have been removed and replaced by redirects, had the articles blanked, or reduced to one line stubs. This may be what Graeme Bartlett meant when he said recently we have had to clean up some articles that copied other people's work! Anyway,  many of these topics are appropriate for full page or longer articles, also if we can replace the copyright violations without doing serious damage to the articles, that would be great. I just finished restoring a shorter version of Zimbabwe Craton. I've been gone for awhile, so if this has already been discussed, please accept my apologies. --Bejnar (talk) 22:07, 10 December 2013 (UTC)
 * That is what I was talking about. Much was copied from Geological dictionaries to start articles off. The topics are good.  However not much has been totally deleted. Graeme Bartlett (talk) 04:12, 11 December 2013 (UTC)
 * I haven't checked all of this 168 articles yet, but the following are still missing. --Bejnar (talk) 18:48, 11 December 2013 (UTC)
 * Slave Craton, completely deleted now redirects to Canadian Shield
 * Superior Craton, completely deleted now redirects to Craton
 * Kalahari Craton, replaced by a single sentence
 * Sebakwe Craton, completely deleted now redirects to Craton

Controversial IP edits
An anonymous editor has been making some very controversial changes to WikiProject Geology-related templates. I just reverted two of them. Other edits by this editor seem 'more legitimate,' but I can't really tell. Could someone check on them? --Omnipaedista (talk) 06:19, 19 December 2013 (UTC)
 * I gather (possibly incorrectly) from the threads that have previously been on this page that the ip 24.218.110.195 is being used by more than one user - one who seems to make a bunch of edits without discussion and a second who does discuss things a bit but doesn't want to register as an editor. I'm leaning toward saying the one is being slightly disruptive, and so I guess that ip might get temporarily blocked for vandalism and the other user might need to actually register. With regard to the particular edits by that IP I don't know enough to check whether something should be left/not. EdwardLane (talk) 21:48, 19 December 2013 (UTC)

The ICS discouragement of Tertiary
In a recent bold move I decided to expunge any mention to the Tertiary that isn't established terminology or relates to the history of Geology. This, however sanctioned it may be by the International Commission on Stratigraphy, raised opposition.

While I do believe this change needs to be made for internal consistency, and to follow a recommendation with nearly a decade from the governing body in these matters, I agree with what Paul H. proposed and am disposed to clean up after myself and continue at a surer pace.

I would also take the opportunity to note that the Cretaceous is now defined to have ended 66 million years ago and statements otherwise will be corrected as well.

If agreement is reached that I should go forward, any help would be much appreciated. --Dracontes (talk) 03:29, 20 December 2013 (UTC)
 * Before changing dates I would urge you to check the references, and if there is any more updated reference on the topic, because it may be that the "Cretaceous" has to be changed rather than the date. Also the references may say Tertiary.  Just because an official body changes terminology, Wikipedia does not unless the predominant use supports it.  However I have not objected to changing Tertiary to Cenozoic, as long as you check the supporting references to confirm. Graeme Bartlett (talk) 10:51, 20 December 2013 (UTC)


 * Regarding the change of 65/65.5 to 66, it will be only in statements where they are associated with end/beginning of Cretaceous/(Tertiary/Paleogene) or the pertinent mass extinction, which I believe should be uncontroversial. Renne et al. simply provided a more constrained date for the iridium anomaly marking the boundary. The same should go for changing mentions to the Cretaceous-Tertiary boundary to Cretaceous-Paleogene.
 * I should note that most of the pertinent templates already display the revised time scale: Template:Cenozoic graphical timeline, Tyrannosaurus (take a gander at the taxobox). Then there is the pickle of determining what value has predominant use in these matters.
 * As alluded above the K-Pg boundary presents no problem: a search in Google Scholar shows loads of recent papers using the new nomenclature. How is it argued, since the changes are transparent and the dates shift sooner than the correlated strata, that more laggard subjects are exempted from translation into the current recommendation? I admit I should have done the legwork from the start and give the necessary references that show the nomenclature changed and that one term corresponds to another. In any case I would think it due to use more precise chronostratigraphic nomenclature whenever possible.
 * Yet, how should one handle the generic use of those terms? Paul H said the Tertiary doesn't exactly correspond with the Cenozoic, but the difference is the exclusion of the Quaternary, 1.8-2.6 Ma depending on what stages are included in the definition and when one was measuring. Not to mention these are nested categories and thus Tertiary strata never stopped being Cenozoic before the former was dropped. True, even I have a twinge at the slight imprecision of using one over the other. Probably various combinations of Paleogene and Neogene are better.
 * Though there is the case of "pre-Tertiary" as I've often encountered: there never was a difference for the past century between saying that and "pre-Cenozoic". --Dracontes (talk) 15:50, 20 December 2013 (UTC)


 * As far as that goes "pre-Paleocene" is also equivalent, since all of these terms essentially reference all time prior to a certain point in time. Perhaps it could be argued that the broadest term should be used, on the basis that a narrower term would be less familiar. (Although Tertiary/Quaternary seems to be exception.) ~ J. Johnson (JJ) (talk) 23:25, 20 December 2013 (UTC)
 * It seems to me that (unless I've missed it) it would be helpful to have a section in a relevant article on the geological timelines which speaks to the various changes that have been made over the years to the dates of period boundaries (same applies to other boundaries too but these have the highest profile - and not least the K-Pg (former K-T) boundary. It would help the hapless lay-person (and perhaps the hapless specialist!) to make sense of the numerous dates offered up in the literature over the decades for certain of these boundaries. In this case, both the 65 and 66 million year figures are now likely to occur in material read by schoolkids and academics (and everyone in between) for decades to come, just as (though formally deprecated) Tertiary will continue to be encountered for decades to come. One of Wikipedia's roles is to help the reader make sense of all this seeming confusion. cheers Geopersona (talk) 06:57, 21 December 2013 (UTC)
 * I think Geological time scale is the place to address "current revisions" (and related controversies). And I think all of the "geological time" articles should have links back to Geological time scale. I may suggest this there. ~ J. Johnson (JJ) (talk) 19:46, 21 December 2013 (UTC)
 * J. Johnson, I'm good with the "pre-Paleocene" option. Here it's more a case of rank: relative time span doesn't enter much into it if that is what you're alluding to with 'narrower term'. Cenozoic is an era; Tertiary, Paleogene and Neogene are/were (sub)periods; Paleocene, Eocene, Oligocene, etc. are epochs; Danian, Gelasian, Calabrian, etc. are ages. This detail of using proper rank is something I saw used inconsistently across the articles I edited in my spree.
 * Geopersona, I have access to both GTS2004 and GTS2012 so I can very well do the necessary revisions. --Dracontes (talk) 15:25, 24 December 2013 (UTC)

Thanks Dracontes. For my part I've been able to construct the table below from a variety of publications in my possession, all by reputable authors & publishers. Each figure is the quoted date (in millions of years of course) of the start of the period/era mentioned.

At first glance it looks good to me - but I'm not an expert on pyrobitumen - a quick google gave this which suggests that the subject is broadly the same as the content on that page - and that looks to be pretty well written - whether the references support the detailed content should probably be checked. I've never handles an AFC so not sure how to proceed and not got time at the moment to read up. EdwardLane (talk) 10:40, 23 January 2014 (UTC)

Category:Earth and atmospheric sciences journals
Hi, could someone here perhaps have a look at this category and its subcats (especially Category:Meteorology journals)? I find the current situation not completely satisfactory. For example, I'm not sure that climatology journals belong in "meteorology". Other journals that currently are in the main cat could perhaps be diffused, but some may be difficult to place in the current subcats. Would it make sense to create a "climatology journals" cat? Would that be a subcat of "meteorology journals", the other way around, or a equal level/parallel subcat within Earth and atmospheric sciences journals? Thanks for any advice! --Randykitty (talk) 16:23, 26 January 2014 (UTC)
 * User:Tillman might have an advice. 'Climatology journals cat' as interface between meteorology, history of the Earth and geology? But I could be wrong. --Chris.urs-o (talk) 19:32, 1 February 2014 (UTC)

Ahlitanah complained at WP:REFUND, where I have explained WP:BRD and said that this is a content dispute to be discussed on the article talk page. More eyes on this might be useful.

Orphan articles in Geology
Hi all. There are a number of orphaned articles in WikiProject Geology (Complete list).

 * Can it be accepted as is? Wikipedia talk:Articles for creation/Kanehekili Fluctus is another one. Thanks, FoCuSandLeArN (talk) 23:53, 7 April 2014 (UTC)


 * So, you are requesting that geology editors review and accept or reject these articles? Again, is that because you see a problem? I am retitling this thread so editors understand that you have request. --(AfadsBad (talk) 01:02, 8 April 2014 (UTC))

Chukchi Plateau is live. Seems that Chukchi Cap exists ... probably should merge 'em. Vsmith (talk) 02:09, 8 April 2014 (UTC)
 * Wikipedia talk:Articles for creation/Kanehekili Fluctus is now in article space. It should not have gone to AFC, the creator should have used the move button themselves. I suspect there are too many confusing alternatives round here!  This is part of a class project I am involved with. Graeme Bartlett (talk) 11:38, 8 April 2014 (UTC)
 * Oh, good. I did not check the articles, but a glance had me confused about their presence at AFC and why AFC editors would be holding them up. Thanks for clearing this up. --(AfadsBad (talk) 12:47, 8 April 2014 (UTC))

Wikipedia talk:Articles for creation/Wilmcote Limestone
Dear geologists: Is this old Afc submission about a notable topic? Should it be kept and improved instead of being deleted as a stale draft? &mdash;Anne Delong (talk) 19:28, 19 April 2014 (UTC)


 * I suppose so, but it depends how 'small' a stratigraphic subdivision is considered worthy of an article - looking at Blue_Lias there is a redlink there, but it doesn't look to have any other redlinks, so perhaps its contents should be merged in as a section of the blue lias article? EdwardLane (talk) 20:05, 19 April 2014 (UTC)


 * According to the BGS lexicon this is the Wilmcote Limestone Member and only 6-12 m thick. We do have Cotham Marble and Purbeck Marble, but that is because of their distinctive nature and use as decorative stones. A section in the Blue Lias article sounds like a good plan. Mikenorton (talk) 21:45, 19 April 2014 (UTC)


 * Would someone at this project like to move whatever is appropriate? Then the draft can be promoted and made into a redirect to maintain attribution.  I'd do it myself, but I am suffering from a profound ignorance of geology.  &mdash;Anne Delong (talk) 01:10, 20 April 2014 (UTC)
 * I have merged the content. Do you want to give the writer credit on their talk page? Graeme Bartlett (talk) 07:46, 20 April 2014 (UTC)
 * I have moved the redirect to mainspace, marked it as a merge attribution redirect, and thanked the editor. That should be all that's needed, I think, so thanks for your help with this.  &mdash;Anne Delong (talk) 13:07, 20 April 2014 (UTC)

Please curb my enthusiasm
I joined this project a couple of weeks ago; since then, I have been zooming along doing assessments of articles, adding stub templates, and checking categories. It suddenly occurred to me that perhaps I should ask for some spot-checks of my edits. Bold is one thing, rash is another! There are vast swaths of Wikipedia I’m unfamiliar with; to be prudent, I’d appreciate it if some of you could take a look--at my assessments in particular. Thanks. - Gorthian (talk) 02:18, 27 April 2014 (UTC)
 * - Thanks for putting so much work into Wikipedia lately. The edits you did on items on my watch list were all needed. Keep up your enthusiasm! --Tobias1984 (talk) 19:33, 30 April 2014 (UTC)

To participate, you will be given access to our new visualization tool and will interact with us via Google Hangout so that we can solicit your thoughts about the tool. To use Google Hangout, you will need a laptop/desktop, a web camera, and a speaker for video communication during the study. We will provide you with an Amazon gift card in appreciation of your time and participation. For more information about this study, please visit our wiki page (http://meta.wikimedia.org/wiki/Research:Finding_a_Collaborator). If you would like to participate in our user study, please send me a message at Wkmaster (talk) 20:26, 5 May 2014 (UTC).

Royal Society journals - subscription offer for one year
I'm delighted to say that the Royal Society, the UK’s National Academy for science, is offering 24 Wikipedians free access for one year to its prestigious range of scientific journals. Please note that much of the content of these journals is already freely available online, the details varying slightly between the journals – see the Royal Society Publishing webpages. For the purposes of this offer the Royal Society's journals are divided into 3 groups: Biological sciences, Physical sciences and history of science. For full details and signing-up, please see the applications page. Initial applications will close on 25 May 2014, but later applications will go on the waiting list. Wiki at Royal Society John (talk) 03:03, 29 April 2014 (UTC)


 * There are two or three articles I have wanted from the Royal Society, but not worth a whole subscription. Is there anyway we can contact those with the subscriptions to request specific articles? ~ J. Johnson (JJ) (talk) 19:16, 1 May 2014 (UTC)
 * email me Wiki at Royal Society John (talk) 22:34, 1 May 2014 (UTC)
 * Thanks. I'll see if I can dig out which articles I wanted. ~ J. Johnson (JJ) (talk) 22:49, 1 May 2014 (UTC)
 * Hmm, only one article from RS, and I already have that. ~ J. Johnson (JJ) (talk) 20:46, 3 May 2014 (UTC)

Another Royal Society offer
I'm also trying to organize a release of some images in various categories from their Picture Library. One of the categories is historic (out of copyright) natural history books, mainly for the illustrations. Are there particular books or other holdings that people would like to see images from, or particular images? Unfortunately much of what they have is not digitized and much of what is digitized is not presently online at the last link. The main library catalogue search page is here. Before asking, please try to see if decent quality images are not available elsewhere, as they often are, from the Library of Congress etc. Thanks, Wiki at Royal Society John (talk) 09:58, 7 May 2014 (UTC)

Wikipedia talk:Articles for creation/Geochemical cycle
Dear geologists: This abandoned page was never submitted at AfC for inclusion in the encyclopedia. Now it's on the list to be deleted as a stale draft. Is this a notable topic, and should the draft be kept and improved instead? &mdash;Anne Delong (talk) 10:31, 12 May 2014 (UTC)
 * This is definitely a notable topic! It should be kept and improved. Thanks for bringing it up here. It looks as if it was a class assignment, given the user name (and subsequent abandonment). Can it be submitted as is, or is something else needed first? - Gorthian (talk) 20:38, 12 May 2014 (UTC)
 * I have moved it, fixed up references and wikified it a bit, and remove gratuitous quotes. If this is a class assignment, then there may be more out there too. Graeme Bartlett (talk) 21:30, 12 May 2014 (UTC)
 * Thanks, Graeme Bartlett. Several of us are trying to give a quick check of all of the abandoned drafts before they are deleted, and that includes ones that were never submitted.  There are a lot of them, though, so I can't promise that none will be missed, or that there'll be time to report all of them in the appropriate places.  &mdash;Anne Delong (talk) 19:25, 21 May 2014 (UTC)
 * Perhaps I should be looking at all the drafts too, particularly the unsubmitted ones. I do restore the deleted ones on request, but if no one asks then no one will restore them either. Graeme Bartlett (talk) 22:19, 22 May 2014 (UTC)


 * That would be great,Graeme Bartlett. If you have the new search installed in your preferences (it looks inside templates), you can use this search box to find ones you are interested in.  For example, if you type "geology qualifies to be deleted" in the search box, it will find submissions with the word "geology" in them that are facing deletion. &mdash;Anne Delong (talk) 13:55, 23 May 2014 (UTC)

Requests for assessment?
Is it time to get rid of requests for assessment? Requests are rare, and responses even rarer. Editors are better off requesting an assessment on this talk page. RockMagnetist (talk) 17:04, 23 May 2014 (UTC)
 * If I were wanting a reassessment, I'd come straight to this talk page. I think you're right. - Gorthian (talk) 03:20, 30 May 2014 (UTC)
 * I removed it. RockMagnetist (talk) 17:17, 30 May 2014 (UTC)

Candidates for inclusion in this project
I used catscan2 to find all the articles that are in Category:Geology but not yet tagged by this project. With a search depth of only 1, I found about 700 articles! The results are in WikiProject Geology/Candidates for inclusion. I encourage you to add articles from this list to the project, where appropriate, or improve the categorization when they don't really seem to belong. RockMagnetist (talk) 17:09, 21 May 2014 (UTC)
 * I would suggest that if the page is already in WikiProject Paleontology, WP:WikiProject Evolutionary biology, WikiProject Mars, WikiProject Moon, WikiProject Environment, WikiProject Volcanoes that we don't need to put it into the Geology project, as there is already a suitable related project taking care. But some topics I think we should include anyway. Graeme Bartlett (talk) 22:06, 22 May 2014 (UTC)
 * It's a tough call. I sometimes wonder, for example, whether we should leave all the obscure minerals to WikiProject Rocks and minerals; but if we stopped supporting all the articles that are in WikiProject Earthquakes and WikiProject Volcanoes, our featured article list would be pretty short. I'm not sure where to draw the line. Geology is inherently multidisciplinary; if we only included articles of no interest to other projects, what would that leave us? RockMagnetist (talk) 22:35, 22 May 2014 (UTC)
 * Well I am counting these as child projects of the Geology one. You can add the project banner if you like, I am adding banners to those that have no relevant Geology type project.  I have now come across Wikiproject soil and WikiProject Civil engineering (moving that earth or rock around) or WikiProject Oceans.  So should we include these too? WikiProject Rocks and minerals has a very narrow scope of creating an infobox, so tough for them to claim credit for FAs! But I suppose that means that Geology project should have rocks and minerals too. Graeme Bartlett (talk) 10:21, 23 May 2014 (UTC)
 * I can't think of any down side to tagging articles that are shared by other projects. We can keep our priorities straight with the importance rating. At worst, no one from this project works on the page. RockMagnetist (talk) 17:11, 23 May 2014 (UTC)
 * My own view is that it really does depend on the article e.g. few of the articles on specific earthquakes are in WP:Geology, but many other seismology articles are; all the articles on seismically active fault zones should sensibly be in both and most are. At one time I moved a lot of fossil genera/species articles from WP:Geology to WP:Palaeontology, because that seemed more sensible - articles on fossil bearing formations are however mostly in both, which seems logical to me. Mikenorton (talk) 21:55, 23 May 2014 (UTC)

A couple of problematic categories
Working through this list, I kept finding articles tagged with Category:Geological history of Earth where that category didn't seem appropriate. Digging into the histories, I see that quite a few of them were "migrated" from Category:Earth evolution, per this CfD discussion. I've changed the category to something more suited to each article or, in some cases, just deleted it outright.

The other category that I see as problematic is Category:Geoengineering. It's thanks to its listing as a direct subcategory of Category:Geology that we get articles like Berm, Shallow foundation, Cut (earthmoving), and Fill dirt on this otherwise very useful list. What I'd like to do is move Category:Geoengineering to Category:Subfields of geology, where it really belongs. That would narrow this list to articles more relevant to our project. Does anyone object to my doing that? - Gorthian (talk) 03:16, 30 May 2014 (UTC)


 * Thanks for all your work on this. It's really gratifying to set this up and see someone run with it. I noticed that Category:Geological history of Earth has some other oddities like Desert (I removed that one). I think moving Category:Geoengineering to Category:Subfields of geology sounds reasonable, although maybe there should be a Category:Applied geology. I give you fair warning, though: if we make enough headway against the current list, I might be tempted to try a search depth of 2! RockMagnetist (talk) 03:34, 30 May 2014 (UTC)


 * Oh, no, Mr. Bill! Not a depth of TWO! :-D
 * Personally, I'm not sure what I'd do with Category:Applied geology. I have enough trouble with Category:Geoengineering as it is; I don't know enough about what geoengineers actually do. And I think I'd end up tagging way too many articles as "applied geology." Take paleomagnetism, for instance. My brain could convince me that it's really geology applied to physics, or vice versa, and doesn't that make it applied geology? ...sorry, it's past my bedtime... - Gorthian (talk) 05:33, 30 May 2014 (UTC)


 * I was thinking of Petroleum geology as an example. Turns out it is in Category:Economic geology, which is a subclass of Category:Subfields of geology. There you'd be safe from me until I went to DEPTHCON 3! RockMagnetist (talk) 06:17, 30 May 2014 (UTC)


 * I put Category:Geoengineering in Category:Economic geology, and 44 articles dropped out of the list. RockMagnetist (talk) 14:50, 30 May 2014 (UTC)


 * Cool. - Gorthian (talk) 21:29, 30 May 2014 (UTC)

Oops, I finally realized that I wasn't meaning Category:Geoengineering at all; the category I was having trouble with was Category:Geotechnical engineering! I moved it to Category:Subfields of geology. My apologies--I really shouldn't be editing here when I'm tired. - Gorthian (talk) 05:27, 31 May 2014 (UTC)


 * Well, isn't that ironic? Because it turns out it was really Category:Geotechnical engineering that I meant when I said Category:Geoengineering. Two wrongs sometimes do make a right. Good night! RockMagnetist (talk) 05:54, 31 May 2014 (UTC)

"Attention needed" flag in template
WikiProject Geology has the flag attention, which puts articles into Category:Geology articles needing attention. My suspicion is that this flag is useless because it doesn't say what aspect of the article needs attention. I doubt anyone looks at the category either. Better to use a tag on the page itself. Shall I remove the flag? RockMagnetist (talk) 17:25, 30 May 2014 (UTC)


 * I'd support removal, as the flag is too vague to be helpful. Even if an editor wanted to give attention, without a more specific tag or a talk page explanation of the problem, it would often be unclear as to what was needed. --Mark viking (talk) 18:07, 30 May 2014 (UTC)


 * I think it could be useful; I'd rather see it kept. Isn't there a place we could provide guidance on using the flag? Maybe the template doc? We could "strongly urge" editors not to use it unless they also put an explanatory comment on the Talk page. Or maybe there's a way to expand the parameter, or add another one? - Gorthian (talk) 21:26, 30 May 2014 (UTC)


 * Consider the Expert-subject tag, whose documentation strongly recommends that you provide a reason; I have yet to see anyone follow that recommendation. And if we kept the attention flag, we would need some way of drawing attention to the flagged articles. Look at all the ways of prioritizing work we already have. There is the importance assessment in the wikiproject tag; there is the todo list at the top of this talk page (which covers mostly high- or top-importance articles); and there is the Open Tasks tab. If we have any more lists of priorities, we'll need to prioritize the lists! RockMagnetist (talk) 21:49, 30 May 2014 (UTC)


 * After looking at several articles, I found one where the attention flag was clearly explained: Talk:Impact_event. It basically asked for the article to be expanded and more citations added. It dates back to 2006, and the article is now B quality. RockMagnetist (talk) 00:36, 31 May 2014 (UTC)


 * I have added a few recently. However if no one ever looks at the list needing attention it will be useless. It is no coincidence as the project tagging has been triggered by the list posted earlier of possible Geology project articles.  I suppose that we need criteria for using attention flag, and detag if the reason is unclear.  Since it says immediate attention, this may mean that it needs attention from a Geology project member within 24 hours.  But instead perhaps we can post a message here, as those with it on the watch list or interested can then not have to check yet another category. Graeme Bartlett (talk) 22:06, 31 May 2014 (UTC)


 * Right. Using that flag for anything that really needs immediate attention, like contentious BLP issues or copyright violations, would be a big mistake. The other problem with the attention flag is that it is generally not removed when the problem is solved, and it can still be there years after anyone knows the reason for it. RockMagnetist (talk) 22:15, 31 May 2014 (UTC)


 * When properly used, it is potentially useful, RockMagnetist visited the category, and I have visited the category on other projects. But people seem reluctant to use talk pages, but that is true whether or not the tag is there. It is harmless and potentially useful. --Bejnar (talk) 22:47, 31 May 2014 (UTC)


 * Actually, the only reason I visited the category is that I wondered if it is any use. My conclusion is no. At best it is harmless, at worst it leaves someone with the impression they have done something for the article when they haven't. If the flag didn't exist, they would look for a better solution. RockMagnetist (talk) 22:50, 31 May 2014 (UTC)

I have decided to start an RfC to remove the attention flag from all WikiProject banners, so it's probably best to close this discussion. RockMagnetist (talk) 03:57, 1 June 2014 (UTC)

Wikipedia talk:Articles for creation/Glass Mountain (Capitol Reef National Park)
Dear geology experts: This old AfC draft was declined with a note that it should be added to Capitol Reef National Park. Is this a notable geological formation, and if not, would someone who knows about geology like to do the merge? &mdash;Anne Delong (talk) 22:18, 6 June 2014 (UTC)

New categories
As a result of User:RockMagnetist's work on inclusion I have made up some new categories, but they do not seem very satisfactory, so I will ask for opinions for better names.
 * Category:Spontaneous fires for permanent natural fires, extracted originally from eternal flame. These could be coal seam fires, or burning natural gas. Others have suggested: Category:Persistent naturally-fueled fires, or possibly Category:Persistent natural fires.
 * Category:Geologist tools for tools used by geologists, but should this be geological tools or geology tools?
 * Category:Geology techniques for methods or techniques used in the study of geology.
 * Category:Taphonomy for different kinds of Taphonomy.

There is not much in them at the moment, so it is currently easy to change. Graeme Bartlett (talk) 09:55, 2 June 2014 (UTC)


 * Here are my thoughts:
 * Category:Persistent natural fires seems the best of that group; persistence is what makes these fires notable. It's also a direct property of the fire, whereas "spontaneous" implies a cause.
 * Category:Geological tools is better because "geologist" isn't an adjective, and "geological" is.
 * Ditto for Category:Geological techniques.
 * Category:Taphonomy perfectly follows WP:CATNAME, and even has a main article.
 * - Gorthian (talk) 21:57, 2 June 2014 (UTC)


 * I agree with all of the modifications suggested by Gorthian. These are all clearly useful categories. RockMagnetist (talk) 22:05, 2 June 2014 (UTC)


 * "Spontaneous" refers to causation, "persistent" refers to duration. I can see both as possible categories, but perhaps the latter is more notable? ~ J. Johnson (JJ) (talk) 23:12, 2 June 2014 (UTC)


 * I have started to move to Gorthian's suggestions. Graeme Bartlett (talk) 12:29, 3 June 2014 (UTC)


 * +1, this all sounds good to me, per Gorthian. DanHobley (talk) 05:15, 7 June 2014 (UTC)

Crater depth
The article crater depth has a whopping 1477 incoming links, but not a single reference. I think if enough sources were found, they would reveal that there isn't a single universal definition of crater depth. RockMagnetist (talk) 14:50, 1 June 2014 (UTC)


 * I think that you're probably right - this ref defines two depths just for a simple impact crater. This ref  does use mean rim height to crater base for the Tycho Crater, but it's hard to judge how prevalent that is as a measure, although it would make sense for craters where the measurements are entirely down to remote sensing. Mikenorton (talk) 15:27, 1 June 2014 (UTC)


 * Melosh's Planetary Surface Processes has a whole section on crater scaling that would be ideal to frame this off. I've got a copy knocking about at work, but can't promise anything on the speed front. Also, could try poking WikiProject_Mars into action on this, or one of the other planetary groups. DanHobley (talk) 05:29, 7 June 2014 (UTC)

Timescale templates
Jurassic (Example to right). Is there a reason why these are formatted in the way that they are, particularly with respect to column headings, which only describe terms in stratigraphy? As a non-geologist, I find this quite confusing, particularly at articles titled according to divisions of time. For example the text of the Middle Jurassic article refers to it as being an epoch, but the accompanying template lists it only as a series, with no mention of the term epoch. In the Early Jurassic article, the text describes it as an epoch that corresponds to the Lower Jurassic series in stratigraphy, but the timescale template lists Early Jurassic as a series—not Lower Jurassic as a series, and not Early Jurassic as an epoch. Is there a way of making things clearer? Or am I just misunderstanding something? PaleCloudedWhite (talk) 23:10, 31 May 2014 (UTC)


 * Hi I've edited the Cretaceous one in a sandbox to include both time and strat terms - User:Mikenorton/Cretaceous template. Does that look better, or even more confusing? Mikenorton (talk) 10:41, 1 June 2014 (UTC)
 * Your version using both is an improvement as it helps remove confusion. Vsmith (talk) 19:09, 1 June 2014 (UTC)


 * Yes, your sandbox version is much clearer - thanks for that. Is there a reason why you've linked half of the 'split' table entries, but not the other half? PaleCloudedWhite (talk) 10:04, 2 June 2014 (UTC)


 * That's because if I linked the unlinked entries, they would just redirect to the linked ones - e.g. Lower Cretaceous redirects to Early Cretaceous, and I'm not sure that would be helpful. Mikenorton (talk) 14:00, 4 June 2014 (UTC)


 * Ah, yes - you are right about those entries. But what about the column headings - system/period, series/epoch etc. - should not those all be linked? PaleCloudedWhite (talk) 22:26, 4 June 2014 (UTC)


 * Agreed, so I've linked Period, Epoch and Age and linked the radiometric age 'Age' to absolute dating. Mikenorton (talk) 07:11, 5 June 2014 (UTC)


 * Yes that's better - it looks 'good to go'. Thanks for making the changes - I was a bit cagey about tinkering with a geology template myself, in case I unwittingly mucked something up (I find geological nomenclature almost wilfully complicated). PaleCloudedWhite (talk) 21:46, 5 June 2014 (UTC)


 * OK, that one's done - I'll update the others when I get a chance. Mikenorton (talk)
 * So, I've updated Devonian, Permian, Triassic, Jurassic, Palaeogene, Neogene and Quaternary. However, the Carboniferous is a problem on account of those pesky sub-systems that were visited on us. In fact the template should be updated to include a different column as each of the sub-systems is divided into three, which our template isn't - I'll see how that looks. Mikenorton (talk) 18:34, 7 June 2014 (UTC)
 * Well it looks difficult, because I don't entirely understand the markup that's used, so I'll leave it for now. Mikenorton (talk) 18:51, 7 June 2014 (UTC)

Gunter Faure
This stub article is on the list of candidates for inclusion (though I found it via a different route). Gunter Faure is the author of several well-regarded books in geochemistry, but is he himself notable enough for an article of his own? The article has had a single edit since its creation four years ago, and the one reference cited is his contact page at Ohio State University, where he is now a professor emeritus. Going by the guidelines at WP:ACADEMIC, I looked for some online indication that he is as well regarded as his books, but came up empty. I hate deleting articles that have any potential at all, so I thought I'd ask here if anyone has any ideas to establish his notability. Or is it truly an article that doesn't belong in Wikipedia? In which case, I'll go ahead with the PROD I was considering. - Gorthian (talk) 03:41, 8 June 2014 (UTC)

AfC submission - 06/06
Draft:Hsanda Gol Formation. FoCuSandLeArN (talk) 16:37, 6 June 2014 (UTC)


 * After looking for sources on the geology of the formation, I came across this, which describes the geological and stratigraphic setting of the fossils and gives an updated view on the stratigraphy (dating from 2007). The draft as it stands is based entirely on the work of James Millett in the late 60s, so it needs to take later work into account. Mikenorton (talk) 18:56, 6 June 2014 (UTC)
 * Accepted. Graeme Bartlett (talk) 12:40, 8 June 2014 (UTC)

Geological unit
I investigated Geological unit, a high-importance article, because it was tagged for having no references. It turns out that one section was a clear copyright violation; and the other two main sections were added by the same person in a large block at around the same time. So I had to assume they too were copyvios. That leaves a very sad looking article with almost no content in it. A good candidate for the next collaboration! RockMagnetist (talk) 02:24, 2 June 2014 (UTC)


 * I've made a start on it - the biostrat subsections need expanding and need to add something on magnetostrat units. Mikenorton (talk) 22:25, 4 June 2014 (UTC)


 * Thanks, Mikenorton. I hate to do this after you have put work into the article, but - I have been wondering about both Geological unit and Geological province. As far as I can tell, these are rarely discussed as a group except in maps. Instead, geologists talk about the different types of units and provinces. I wasn't able to find a single source that discussed geological units collectively; and I have found one definition for geological province. Should these topics have their own articles? Or should they just be disambig pages? RockMagnetist (talk) 14:55, 7 June 2014 (UTC)


 * I think that they should have their own articles. See the ICS Stratigraphic Guide for a full discussion of geological units, although I think it's fair to say that the term stratigraphic unit might be more appropriate. Mikenorton (talk) 22:38, 7 June 2014 (UTC)
 * And thanks to Vsmith, the article is now "Stratigraphic unit". Mikenorton (talk) 14:45, 8 June 2014 (UTC)
 * I think that's the right decision. RockMagnetist (talk) 21:10, 8 June 2014 (UTC)


 * Oh so busy, but this is crying out for a pretty hand-drawn field slip/geological map, or indeed a nice km-scale professional one, as its key image in the intro. But WP appears extremely poor on fine scale map images. If I remember, I'll scan one of mine in - though an alternative might be better. Also, will probably forget to do so. DanHobley (talk) 05:21, 7 June 2014 (UTC)


 * Incidentally, shouldn't we have an article on structure contours? Given this can be a nightmare to explain, and shows up early in many Geology 101 classes, it would be nice to have. DanHobley (talk) 05:30, 7 June 2014 (UTC)

Proposed changes for Mudslide
A brand new editor who is a geologist might need editing help at Talk:Mudslide. Some good ideas there! - Gorthian (talk) 06:38, 13 June 2014 (UTC)

Leaflet For Wikiproject Geology At Wikimania 2014
Hi all,

My name is Adi Khajuria and I am helping out with Wikimania 2014 in London.

One of our initiatives is to create leaflets to increase the discoverability of various wikimedia projects, and showcase the breadth of activity within wikimedia. Any kind of project can have a physical paper leaflet designed - for free - as a tool to help recruit new contributors. These leaflets will be printed at Wikimania 2014, and the designs can be re-used in the future at other events and locations.

This is particularly aimed at highlighting less discoverable but successful projects, e.g:

• Active Wikiprojects: Wikiproject Medicine, WikiProject Video Games, Wikiproject Film

• Tech projects/Tools, which may be looking for either users or developers.

• Less known major projects: Wikinews, Wikidata, Wikivoyage, etc.

• Wiki Loves Parliaments, Wiki Loves Monuments, Wiki Loves ____

• Wikimedia thematic organisations, Wikiwomen’s Collaborative, The Signpost

For more information or to sign up for one for your project, go to: Project leaflets Adikhajuria (talk) 09:28, 13 June 2014 (UTC)


 * I took a stab at it. Have a look! RockMagnetist (talk) 17:05, 27 June 2014 (UTC)

Coastal upwelling of the South Eastern Arabian Sea
The new article at Coastal upwelling of the South Eastern Arabian Sea is really geophysics, so I have not added the WP Geology template to it. What do you all think? --Bejnar (talk) 07:03, 3 July 2014 (UTC)


 * Not my area of expertise at all, but is this article about the same phenomenon? Could the two articles be merged? Rocksandwaves (talk) 08:45, 3 July 2014 (UTC)


 * I've added links to full text versions of the two cited papers. It appears that these two phenomena are related but separate features of the system of currents around the Arabian Sea. Mikenorton (talk) 18:14, 3 July 2014 (UTC)


 * The article is about an oceanographic feature. Oceanography is part of the earth sciences, but that article is not in WP:Geology, although it is in WPs:Geography, Physics and Oceans. Unless we expand this project to encompass the full range of Earth Sciences, I'm personally happy that we leave oceanographic topics to these other projects. Mikenorton (talk) 15:18, 6 July 2014 (UTC)

Project banners on categories or files?
Is it accepted practice to add WikiProject banner templates to category talk pages? What about images (files)? I ask because many of the pages labeled with "Class=NA, Importance=Low"are either files or categories. (Most of the rest are probably redirects.)

If the class is NA, importance should also be NA, as I understand it. — Gorthian (talk) 17:45, 4 July 2014 (UTC)
 * Some projects have augmented tables of article statistics that have separate rows for classes like file and category (see, for example, Version 1.0 Editorial Team/Physics articles by quality statistics). Probably the best approach is to add the banner with the explicit class; it shows up as NA in our table, but if we ever change to the augmented table the banners will be ready. And yes, the importance can be NA or just left empty, which has the same effect. RockMagnetist (talk) 00:20, 5 July 2014 (UTC)
 * I did notice that other projects had more possibilities for "class." I was all ready to take the banners off; now I'm glad I asked about it first. Though it means there are suddenly a whole lot more pages to add to the project! Sometimes I forget that Wikipedia is endless never finished. — Gorthian (talk) 10:22, 6 July 2014 (UTC)
 * There are also list, disambig as well as those redirects. I have been taking categories off redirects, as although they seem to work the user ends up on a page, not the one they selected. Graeme Bartlett (talk) 13:27, 6 July 2014 (UTC)
 * Good. I've been doing the same. Per WP:RCAT, redirects shouldn't have categories (other than their own special maintenance cats). — Gorthian (talk) 17:58, 6 July 2014 (UTC)

Shield volcano
Hey, can an expert take a look for me at Shield volcano and give me some to-do pointers in terms of what content is still needed (also, any good sources you know)? Much appreciated, Res Mar 15:50, 27 June 2014 (UTC)


 * Hi Res, I think it might be worth checking this out as VolcanoGuy and I (plus additional support) spent a little while trying to work out what defined a shield volcano, and the current description looks (I only checked quickly) to exclude rare scutiform volcanic types (pyroclastic shields, and any non mafic lava shields). Perhaps I missed it - but if not then a definition and reliable source for that definition would be a good start. EdwardLane (talk) 11:05, 7 July 2014 (UTC)

Subscription to Mineralogical Magazine
Does someone have access to the Mineralogical Magazine articles? The current first source at Orbicular granite is Mineralogical Magazine; April 2006; v. 70; no. 2; p. 238-239: (Lahti, S. (Editor) Orbicular Rocks in Finland 2005, with contributions by P. Raivio and I. Laitakari. Espoo (Geological Survey of Finland) 2005. ISBN: 951-690-911-6. 177 pp.) http://minmag.geoscienceworld.org/cgi/content/extract/70/2/238?ck=nck, but it's behind a paywall. The source of the article in Finnish, ''Lahti, Seppo I.: Orbicular rocks in Finland, s. 11. Espoo: Geological Survey of Finland, 2005. ISBN 951-690-911-6. http://arkisto.gtk.fi/ej/ej47/ej_047.pdf'' sounds almost identical to the one at Mineralogical Magazine, even the ISBN. Only the page numbering differs, it's 181 in the PDF. I'd like to check if the source is one and the same, in that case the paywalled could be replaced with the free PDF. &mdash;Nelg (talk) 12:39, 11 July 2014 (UTC)
 * I have access to seemingly all the articles right around those pages, but not those themselves from Min Mag. Given that Min Mag has two pages on it, it might be a book review, whereas the other link you gave looks to be the whole entire book. Chris857 (talk) 01:11, 12 July 2014 (UTC)

Formation of delta-shaped river basin
This page is unsourced and a bit "fictional geology". --Bramfab (talk) 14:38, 15 July 2014 (UTC)

"Unique" Upper Portlandian fossils
The Tisbury, Wiltshire article currently makes some claims about palaeoanthropological significance of the area, based on an assertion that certain Upper Portlandian fossils are "unique" to the area. I'm a bit concerned that some of the sources aren't as reliable as they should be, and that the statements in the article are WP:OR and/or WP:SYNTH, but I'd appreciate input from geologists, if anyone has a bit of time to have a look (the statements in question are the first 5 sentences of the 'History' section). Thanks. PaleCloudedWhite (talk) 05:18, 13 July 2014 (UTC)


 * I suggest you pose this question at WikiProject Anthropology or one of their related projects. I'm not sure many of us in this project have the right background to intelligently answer your request. — Gorthian (talk) 02:34, 17 July 2014 (UTC)


 * Thanks for replying. I might try the anthropologists, although I still feel the nub of my question is geological: are the fossils referred to in the article unique to the Tisbury area? If they're not, the article's claims are false. (If they are unique, then the claims may be true, but it may be a case of WP:SYNTH anyway - I'm not sure because I can't access one of the sources. Maybe the anthropologists would enjoy pondering over that question). PaleCloudedWhite (talk) 05:56, 17 July 2014 (UTC)

National categories of geologists
I have been working through Category:Geologists by nationality, and have found that each nationality category is included in the category "Geology of" the nation involved.

As an example, Category:Danish geologists is included in Category:Geologists by nationality, Category:Danish scientists, and Category:Geology of Denmark. The first two categories are good supercategories, but I believe "Geology of Denmark" is out of place. Danish geologists do not necessarily study the geology of Denmark.

I think these categories are inappropriately used; I want to remove all these "Geology of" categories, but thought I'd ask for feedback here first. Any thoughts? — Gorthian (talk) 02:14, 17 July 2014 (UTC)
 * Interesting, but it does seem out of place, though when I write about a regional geology I will write about the famous geologists from there. Graeme Bartlett (talk) 02:48, 17 July 2014 (UTC)
 * I think that "Geology of country X" is not a defining characteristic of "Geologists from X" and should not be a supercat. RockMagnetist (talk) 03:42, 17 July 2014 (UTC)


 * I expect most of the people doing research on the geology of Denmark to be Danish geologists, and similarly for most other locations.
 * So I think there is enough of a weak connection that the category pages Category:Danish geologists and Category:Geology of Denmark should link to each other.
 * I agree that neither one should be a supercategory of the other.
 * I attempted to edit those two pages to make that happen -- feel free to revert if you think you have a better way. --DavidCary (talk) 19:16, 17 July 2014 (UTC)
 * I think your edits are fine, removing the connections from those two categories but creating links that can be followed by interested readers. A nice idea, thanks. — Gorthian (talk) 06:16, 18 July 2014 (UTC)

Highland continent
At WT:AST there is a query about this newly created article, -- 65.94.171.126 (talk) 06:41, 19 July 2014 (UTC)

what happens between ice ages?
The articles ice age, greenhouse and icehouse Earth, history of the Earth, etc. are currently vague on the time between ice ages.

I hope people interested in geology will be interested in helping us find reliable references that name the periods of time between ice ages -- preferably a proper name for each one of them that we know about -- analogous to the proper names "Cryogenian", "Karoo Ice Age", "Pleistocene glaciation", etc. -- or at least a general term for those ages -- analogous to the general term "ice age".

Thank you. --70.177.113.174 (talk) 19:23, 17 July 2014 (UTC)


 * Does the article Interglacial help with your query? — Gorthian (talk) 06:22, 18 July 2014 (UTC)


 * As far as I can tell, today's version of the Wikipedia article "interglacial" never says anything about the time between ice ages. Should it? Where can I find reliable references that name the times between ice ages? --70.177.113.174 (talk) 02:03, 20 July 2014 (UTC)
 * Timeline of glaciation would be a good starting point. Besides naming the various ice ages, it names and dates the intervals of time during the various stages of the Quaternary glacial cycle. So far as I am aware there are no names for the vast intervals of time (hundreds of millions of years plus) between the extended glacial periods that are known to have taken place during the Proterozoic (eg during Cryogenian), Palaeozoic (Permo-Carb and Siluro-Ordovician) and the Quaternary.  cheers Geopersona (talk) 10:55, 26 July 2014 (UTC)

Empty lists
Are list articles like this really necessary? 130.88.141.34 (talk) 09:05, 29 July 2014 (UTC)
 * This is just one of a large number of lists with nothing in them and one-line articles on formations - all with no source besides a generic link to Fossilworks - that were created recently by . It appears that Abyssal has done a lot of good work on stratigraphy lists and articles, but I can't see the rationale for creating all these articles. Maybe Abyssal can explain. RockMagnetist (talk) 21:19, 29 July 2014 (UTC)
 * Plan is to use an automated process to expand them with more specific information on age, fossil content, location, etc. They won't be featured article candidates when I'm done, but they'll at least have have some meaningful information. Abyssal (talk) 21:35, 29 July 2014 (UTC)

Low islands, coral islands, and atolls
I see that between 17 and 19 months ago, there were others asking some of the same questions I am asking now, with little intermediary response. I wonder if the topics have rather fallen between the cracks among multiple projects, especially as these are all stub articles. In particular, even the lead sentence descriptions/definitions of these topics are contested on talk pages, demonstrating a real need for solid information based on reliable sources. I might suggest some merging of articles (if/where appropriate) and sharing of development across projects, as this might raise visibility of the issues and spots to improve. Finally, I am no specialist in any of the project areas concerned, yet I would like to have found some good basic information on these topics. While I appreciate that elementary topics can easily escape the notice of more specialized and knowledgeable editors, they necessarily form foundations upon which an encyclopedia is built, and where neglect can be seen as a real deficiency. Please consider reviewing their priority status within the projects in that light. I am sure that even some well-accepted college textbooks could provide some answers and support for the articles. Thank you. Evensteven (talk) 08:08, 10 August 2014 (UTC)
 * There is no WP:Deadline at Wikipedia. There is no Quality Assurance department, and there are no managers prioritizing work.  What you see is what you get.  One of the bottom lines in a volunteer organization is the people willing to do the work.  Hope that helps.  Unscintillating (talk) 14:07, 10 August 2014 (UTC)
 * Yes, of course. But my comments needn't be taken as criticisms. Projects have priorities, listed as such on article talk pages, and they have active work lists, and they have editors who watch article and project pages. I'm just asking if someone would be willing to look this over. Especially at its current level, it doesn't take a high level of expertise to clear up some very fundamental things. And since the questions have been asked before, there is some interest. I'm renewing the awareness of that interest. And I'm supporting the general process of WP in drawing attention to a weak spot that could use some help. Would someone competent in this area be willing to get involved? Thanks.

Geology of Iceland – any takers?
Geology of Iceland has been a measly stub ever since its creation in 2006. Expansion should be an easy task for any geology buff. --Florian Blaschke (talk) 07:32, 7 August 2014 (UTC)


 * Well I'm interested, but not sure I have enough time to put to it at the moment. On the plus side I do have a tectonic map of Iceland by Johannesson and Saemundsson from 2009 that I picked up while I was there a few years ago. Mikenorton (talk) 20:18, 10 August 2014 (UTC)

Wikipedia talk:Articles for creation/Caldasite
Dear geology experts: This abandoned AfC submission will soon be deleted as a stale draft. Is this a notable topic, and should the draft be kept and improved? Right now caldasite is a redirect to chvaleticeite baddeleyite, but that article doesn't mention this mineral. &mdash;Anne Delong (talk) 18:39, 7 August 2014 (UTC)
 * It should be a variety of baddeleyite. --Chris.urs-o (talk) 19:46, 7 August 2014 (UTC)
 * It's apparently not a variety of baddeleyite. It's not a mineral at all, being a mixture of zirconium-bearing minerals (often including baddeleyite), but an ore. I think the article should be rescued; all it needs is to have the references converted to inline citations, and it'd be good to go, Unfortunately, the only references I can access are those online, so it might be hard for me to check the ones already listed. I can give it a shot, though. Zirconium's an important material, and one ref I ran across says that caldasite is one of only three (or four) commercially mineable host rocks, so I think notability is a given. — Gorthian (talk) 22:48, 7 August 2014 (UTC)
 * I have postponed its deletion for six months. Inline citations are not required in a start-class article if it's not about a living person whose reputation may be damaged and if the information is not controversial.  Still, perhaps someone here is familiar with at least some of the referenced articles and can vouch for their relevance.  Please let me know if the article can be moved to mainspace.  &mdash;Anne Delong (talk) 23:19, 7 August 2014 (UTC)
 * I have moved it to article space, as it does not appear to be a hoax. Graeme Bartlett (talk) 21:24, 11 August 2014 (UTC)

Partial magma
I've created this redirect to a math article, but I'm well aware that the term is far, far more common in geology. If someone can find an actual definition for partial magma in geology (I found many, many uses of the phrase but no luck with a def), then please add it to magma and change the redirect accordingly. JMP EAX (talk) 09:35, 26 August 2014 (UTC)


 * I just searched Google Scholar using "partial magma", and found that many of the hits were for partial magma + mixing, differentiation, crystallization, melting and such. There is also an older meaning that has a few hits, which appears to be simply "part of an original magma", which is hardly notable I think. Mikenorton (talk) 22:31, 26 August 2014 (UTC)

Update needed: Stage
(1) The section Stage (stratigraphy) is in need of a rewrite. It says in part: As of 2008, the ICS is nearly finished a task begun in 1974, subdividing the Phanerozoic eonothem into internationally accepted stages using two types of benchmark. and In many regions local subdivisions and classification criteria are still used along with the newer internationally coordinated uniform system, but once the research establishes a more complete international system, it is expected that local systems will be abandoned. I also find speculation without a citation to be inappropriate. --Bejnar (talk) 08:19, 27 August 2014 (UTC)

(2) The section Stage (stratigraphy) uses series rather than stages in its example: Thus, for example in the local North American subdivision, a paleontologist finding fragments of the trilobite Olenellus would identify the beds as being from the Waucoban Stage [ Cambrian Series 2 ? ] whereas fragments of a later trilobite such as Elrathia would identify the stage as Albertan [ Cambrian Series 3 ? ]. --Bejnar (talk) 08:19, 27 August 2014 (UTC)

Assessing interest in a page titled "Geological Slang"
Hello! I was looking through the requested pages, when I stumbled across this:

Quoted at ; this is literally all I know about this; Ms. Herbert does not normally write hoaxes, fringe theories, or silly humor. -- Writtenonsand (talk) 15:02, 7 November 2009 (UTC)
 * See fubarite and leaverite - maybe collect 'em all at Geological slang?

I was wondering if there would be any significant interest in creating a page titled Geological Slang, and perhaps combining all of these stubs into one hopefully good quality article?

I am relatively new, and would appreciate any help that anyone would care to render. Thank you for taking the time to read this!
 * Icarosaurvus (talk) 23:00, 28 August 2014 (UTC)

I would be more than willing to help, and work on this, though I wished to see if others thought this a good idea, first, and also if anyone else would like to work on this, as well. Icarosaurvus (talk) 23:25, 28 August 2014 (UTC)


 * Are there any writings in journals and magazines on geological slang, rather than just using it? That will be our criteria as to whether we should have an article. Even April 1 stuff may be OK. Graeme Bartlett (talk) 01:53, 29 August 2014 (UTC)
 * It seems that we already have articles on particular items of geological slang, thought they seem to be stubs. My thought was that these stubs could be combined, rather than left as orphaned bits of knowledge in articles of mediocre quality. Icarosaurvus (talk) 02:24, 29 August 2014 (UTC)

Should stratigraphic units get their own categories?
I'm a contributor at Wikiproject:Paleontology and we have some issues with our categorization scheme. Take dinosaurs for example. In our dinosaur articles we tend to classify them by period and by continent. However, very few of the dinosaurs listed under either category would have lived anywhere near the same time and place as each other. Further, these overly broad categories often have hundreds of articles that are difficult to navigate. I recently proposed that we categorize prehistoric taxa by the stratigraphic units wherein they are found. That way prehistoric organisms can be arranged in moderately-sized categories including the contemporary life forms that they actually lived along side. Obviously this would be a significant change to Wikipedia's many articles on stratigraphic units themselves, so I thought it would be prudent to raise the issue here before any action is taken. Abyssal (talk) 15:53, 2 September 2014 (UTC)

Comment on the WikiProject X proposal
Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)

Template trouble
The infobox created by Geological era is showing up broken on some articles—see Mesoproterozoic, for example. I don't see any edit to the template itself that might be responsible for the problem, and I'm too ignorant about the workings of templates to figure out where the trouble may lie. Someone with more knowldge about templates should look into this. Deor (talk) 11:25, 13 October 2014 (UTC)
 * Never mind. I figured out that someone had made edits to Template:Mesoproterozoic graphical timeline and Template:Paleoproterozoic graphical timeline that messed up the timelines. I reverted the edits for now, but someone may want to take a look to see what the editor was trying to do and whether those changes sould be implemented in a proper way.

Geological era query
How come all of our articles delineate the K-Pg boundary as being 66 million years ago when everything I've been taught for the past 20 years has been 65 million?— Ryūlóng ( 琉竜 ) 01:16, 17 October 2014 (UTC)
 * Seems to be based on Husson, D., Galbrun, B., Laskar, J., Hinnov, L. A., Thibault, N., Gardin, S., & Locklair, R. E. (2011). Astronomical calibration of the Maastrichtian (late Cretaceous). Earth and Planetary Science Letters, 305(3), 328-340.  with a value of 66.23 Ma Graeme Bartlett (talk) 05:02, 17 October 2014 (UTC)
 * The accuracy of the dating has improved over time. RockMagnetist(talk) 05:14, 17 October 2014 (UTC)
 * Then how come there are still several sources that define the boundary at 65 mya (and by boundary I mean the meteorite event that resulted in the extinction)?— Ryūlóng ( 琉竜 ) 06:32, 17 October 2014 (UTC)
 * Because people are slow to catch up with the new timescale. I've just been trying to compare the ages of the Aptian break-up along the South Atlantic in published papers and found that almost no-one is using the newest timescale yet, so it's not just that boundary where workers stick with the numbers they're familiar with. It also takes time to write and publish papers of course. Mikenorton (talk) 06:54, 17 October 2014 (UTC)
 * Perhaps this should be a question of whether or not the 66 Ma figure is widely accepted or acknowledged as the new and correct boundary.— Ryūlóng ( 琉竜 ) 11:12, 17 October 2014 (UTC)
 * Once the International Commission on Stratigraphy has published an updated timescale (see here for the latest), the rest of the geological world pretty much follows it, although some changes, such as Tertiary to Cenozoic take longer to filter through. Just occasionally a change meets with sufficient resistance, such as the move to abolish the Quaternary period, that it gets changed back, but this is unlikely to happen to chronostratigraphic ages, as RockMagnetist says, accuracy improves with time.

Geological Society's 100 Great Geosites list
Following the publication of the Geological Society's 100 Great Geosites list (http://www.geolsoc.org.uk/100geosites), I've now added a list of the sites on that are currently missing Wikipedia articles to Requested articles/Natural sciences/Environment and geology -- The Anome (talk) 13:31, 13 October 2014 (UTC)

Extending assessment table
The assessment table for this project has over 1100 pages rated NA-class. Many of these are probably page types like redirect, category or project page that the default wikiproject banner doesn't classify. But some may be uncategorized articles. We could use a custom class mask to get an extended table like the one for WikiProject Physics. All in favor? RockMagnetist(talk) 01:15, 19 October 2014 (UTC)
 * yes lets have it, pretty harmless at worst, and good for gnomes at the best. Graeme Bartlett (talk) 06:56, 19 October 2014 (UTC)
 * You're right, it's hard to see why anyone would object. I am making the change. RockMagnetist(talk) 02:52, 20 October 2014 (UTC)

Viking Bergen Island → Viking-Bergen Island?
Should the article Viking Bergen Island be at Viking-Bergen Island (currently a redirect) or even Viking–Bergen Island or Viking/Bergen Island? "Viking Bergen Island" strikes me as orthographically incorrect, and even the article is internally inconsistent about the use of the hyphen. Unfortunately, few sources appear to use the term (with or without "island") at all, so I can't determine any preponderance of spellings. Which also raises the issue whether the term is even established or a Wikipedian neologism, more or less. --Florian Blaschke (talk) 19:10, 31 October 2014 (UTC)


 * The term is barely used at all and doesn't generally include island, other than as a description of what it is (as far as I can tell), so just Viking Bergen would seem most correct based on the limited sources, as they were apparently hills before they became an island, according to the maps in Coles' 2000 paper. Mikenorton (talk) 23:57, 31 October 2014 (UTC)


 * I just realised a stupid mistake of mine. Somehow I had assumed that Bergen refers to the Norwegian city here and for that reason suggested the dash or slash. But Viking Bergen really means "the Viking mountain/hill" or "Mount Viking" in Norwegian, right? Then, of course, Viking Bergen is indeed the most appropriate title. --Florian Blaschke (talk) 16:08, 1 November 2014 (UTC)


 * Not quite, the Viking and Bergen Banks are two separate but related shallow water areas in the North Sea e.g. here. Viking Bank gives its name to the marine forecast area 'Viking', just as the Dogger Bank gives its name to 'Dogger', so Bergen Bank would likely be named after the Norwegian city. File:North Sea map-en.png shows the location of Viking Bank, perhaps the Bergen Bank is the slightly smaller bank to the southwest of that. However, this all goes to show that it is a compound name, a shortening of Viking and Bergen, which is why it's sometimes hyphenated and sometimes with a slash. I hope that helps in understanding where the names come from, not sure it proves anything as far as the article title is concerned. Mikenorton (talk) 19:01, 1 November 2014 (UTC)


 * Ah, OK. Then I got it right initially after all, and I affirm my initial suggestion. Now the remaining question I have is whether to move the article to Viking–Bergen Island, Viking–Bergen island (probably not) or simply Viking–Bergen. --Florian Blaschke (talk) 20:55, 1 November 2014 (UTC)


 * A possibility would be to use Viking-Bergen Banks as the title, allowing the article to cover the full history, including their use as fishing grounds today. Mikenorton (talk) 22:15, 1 November 2014 (UTC)


 * That would clearly be the optimal solution, but unfortunately that would mean the content of the article (which is now focussed on the island) would have to be changed. I'm not up to a rewrite because oceanography is very far from my field of expertise. --Florian Blaschke (talk) 00:38, 2 November 2014 (UTC)


 * I've opened a discussion on the article talk page, proposing a page move to that title. Mikenorton (talk) 10:38, 2 November 2014 (UTC)

Capitalization of divisions of geological time
The USGS guide here capitalizes all words in time divisions such as "Mesozoic Era", "Jurassic Period", "Late Jurassic Epoch" – a style I've always used in writing about fossil plants in Wikipedia. Recently there have been some editors keen on de-capitalizing, resulting in, e.g., "Mesozoic era", "Jurassic period", "late Devonian". Is there an agreed style for use in the English Wikipedia? Peter coxhead (talk) 10:04, 10 November 2014 (UTC)


 * I agree: part of a formal name. USGS and International Commission on Stratigraphy are good refs. --Chris.urs-o (talk) 17:53, 11 November 2014 (UTC)


 * The examples above are correct ("Mesozoic Era", etc.), but there are some exceptions to capitalization. To quote from a commentary taken from the Journal of Sedimentary Petrology: "All words in formal units are capitalized. Only the geographically derived name in informal units is generally capitalized." See Tables 2 and 3 for examples. RockMagnetist(talk) 18:35, 11 November 2014 (UTC)


 * Thanks for your responses. It would be really useful for non-geologists who need to use geological time divisions to have some style guide available within Wikipedia. Peter coxhead (talk) 19:38, 11 November 2014 (UTC)


 * The agreed style in wikipedia is as specified in MOS:CAPS: Wikipedia avoids unnecessary capitalization. Most capitalization is for proper names or for acronyms. Wikipedia relies on sources to determine what is a proper name; words and phrases that are consistently capitalized in sources are treated as proper names and capitalized in Wikipedia.  Recently some specialist editors have been changing to capitalize according to the specialist guides like that of the ICS or USGS.  See WP:SSF.  I think we should follow our own MOS instead.  Sources written for general audiences mostly do not capitalize these terms.  See for example .  Dicklyon (talk) 04:38, 15 November 2014 (UTC)


 * I don't understand your argument, Dick. Isn't "Mesozoic Era" a proper noun? It refers to a unique time period (there are not two "Mesozoic Eras"). It's analogous to capitalizing the name of a historical period, like "High Middle Ages". —hike395 (talk) 06:25, 15 November 2014 (UTC)


 * There seem to be two different capitalization issues.
 * Capitalizing the noun which determines the type of the time span (i.e. "Era", "Period", etc) in expressions like "Mesozoic Era" or "Jurassic Period". I don't think decapitalizing matters as much in such cases since the meaning is generally the same, although it does seem to me that grammatically and semantically "Mesozoic Era" is the same as "Bronze Age" or "Iron Age", so I can't see any grounds for decapitalizing the one and not the other.
 * Capitalizing qualifiers (e.g. "Late Jurassic", "Middle Ordovician"). Here it matters considerably: the "Late Jurassic" is a specific internationally defined time period; "late Jurassic" often means "somewhere late in the Jurassic".
 * The problem with Google ngrams is that we should only be considering sources of an standard written for a general audience, i.e. sources that care about the precise and careful writing essential in an encyclopedia. Peter coxhead (talk) 17:46, 15 November 2014 (UTC)
 * Excellent comments, Peter. Thank you. Assuming that the USGS standards are largely consistent with other authorities, I would say there is a good case for capitalization. However, as Dick noted, there is WP:SSF, which basically says that WP:MOS rules, and there are editors for whom capitals are anathema, and who will de-capitalize every case not explicitly allowed by the MOS. There is an obvious solution: let's expand the MOS to cover geological terms. ~ J. Johnson (JJ) (talk) 20:07, 16 November 2014 (UTC)
 * That sounds like a good plan. A quick scan through various British Geological Survey publications in my possession shows the strong preference of this UK body for capitals, certainly in material published in recent decades. Go back to the 1960's and you'll find 'era' and 'period' rather than 'Era' and 'Period' following the specific names. I guess we're looking at similar treatment of 'Stage', 'System', 'Series' too. cheers Geopersona (talk) 19:03, 17 November 2014 (UTC)


 * Some useful guides to the usage of stratigraphic nomenclature are:


 * Owen, D. L., 2009, How to use stratigraphic terminology in papers, illustrations, and talks. Stratigraphy, vol. 6, no. 2, pp. 106-116.


 * Owen, D. L., 1987, Commentary: usage of stratigraphic terminology in papers, illustrations, and talks. Journal of Sedimentary petrology, vol. 57, no. 2, pp. 363-372.


 * "North America Stratigraphic Code" Paul H. (talk) 18:52, 2 December 2014 (UTC)


 * I think it is simple enough to harmonize the specialist style guides with the MOS. In the phrase quoted by, the key phrase is "proper names". If a term like "Late Jurassic" refers to an internationally defined time period, a unique entity, it is a proper name.  SSF (which is an essay, not a guideline or policy) argues that specialists are not authorities on style. True, but they are authorities on the difference between "Late Jurassic" (proper name) and "late Jurassic" (an approximate time frame). RockMagnetist(talk) 20:50, 2 December 2014 (UTC)


 * The specialist guides, such as the those linked above, that suggest capitalizing "formal" terms are not suggesting that these are proper names. And I am told that the MOS:CAPS phrase about "proper names" is also not very sensibly based, since a lot of what get capitalized are not names at all.  In any case, the question becomes how should WP's general style principle of avoiding unnecessary capitalization be applied in these cases.  Does the existence of specialized recommendations to capitalize mean that we interpret caps as "necessary" in such cases?  In some broad discussions (e.g. birds) we have decided not.  In others (e.g. comets) we still do, even though things like "Halley's comet" are commonly not capitalized in non-specialist sources.  I don't know the answer, but I favor avoiding caps when they're not really necessary.  Dicklyon (talk) 23:09, 2 December 2014 (UTC)

Request for help
Hello. Since September, I have been editing the article on Sleaford, a town in Lincolnshire in England. I have recently put it up for Peer Review and one of issues raised is that it could do with a description of the town's/area's geology. However, I know very little about geology and I am unsure even where to start or what sources to use. I do intend to nominate the article for GA (as it seems to be complete enough in every other aspect), and so any assistance or advice on this matter would be greatly appreciated. Many thanks, —Noswall59 (talk) 19:23, 31 January 2015 (UTC).


 * The overall geology of the Sleaford area is simple enough to describe, a sequence of easterly dipping Jurassic strata, which can be seen from the British Geological Survey's mapviewer (just zoom in to the Sleaford area). There is a source which explains about the Lincolnshire limestone, the main aquifer used for groundwater extraction in the Sleaford area, and another, which looks at mineral resources in Lincolnshire, describing a little about the sands and gravels around Sleaford. This report (pages 11-5 & 11-6), looking at a road scheme near Sleaford, suggests that there is little remarkable about the local geology. Mikenorton (talk) 11:50, 1 February 2015 (UTC)

Requesting eyes on Matthias Kuhle (Tibet glaciation hypothesis)
Last month there was a thread at NPOVN concerning Matthias Kuhle and related articles. (See thread here). Several SPAs seem to be interested in promoting Kuhle's work, and from what I can tell it looks like they're editing articles to state his ideas more matter-of-factly than perhaps they should. One of the SPAs added a number of sources, I tagged the article, and frankly haven't looked back since. Now another SPA is edit warring over removing the tags without improvements in the meantime. I can deal with edit warring well enough, but this article could really use some more knowledgeable editors taking a closer look. I'm not feeling well equipped to assess WP:WEIGHT on this subject, for example. For that reason I'm cross-posting this as WikiProjects Geography, Geology, and Glaciers (to members of more than one of the three: sorry for the spam). --&mdash;  Rhododendrites talk  \\ 16:12, 18 February 2015 (UTC)

 * Tough one. The author has clearly put in quite a bit of effort, but I'd say "Stone laterite Borneo" as not notable as it stands. Presumably the intent is "Stone Laterites of Borneo".

Need to upgrade importance of Coastal erosion in southeast Louisiana article
For the life of me, I cannot understand why low importance is being placed on the Coastal erosion in Southeast Louisiana article, as indicated in the template, when so much is at stake for the survival of my region. Sorry folks, but that that is unacceptable. How would you feel if your state lost the equivalent of 30 football fields of land a day? I'm sure that if it happened to any other state, it would get a higher level of importance. The Louisiana wetlands serve as a critical barrier against storm surges during hurricanes and tie into the ecosystem of the whole nation. Keep in mind that New Orleans sits at a crucial strategic point the mouth of the largest river of commerce in the world and has a tri-axial port: 1) sea port 2) North-South river port, and 3) an east-west port, the Intercostal waterway, which runs East and West. What do you think Jefferson had in mind when he bought Louisiana?  In his writings he said that the primary reason was to gain access to the port of New Orleans.  But, our region is threated and needs more than this kind of lackluster response.  Upgrade the article's importance please! Garagepunk66 (talk) 01:30, 7 September 2015 (UTC)
 * The importance is on the talk page, and does not say that the problem described in the article is of low importance. What it means is that someone thought that the page was of low importance to this project.  If you find that there are thousands of page views per day, than that may justify boosting that value. 03:08, 7 September 2015 (UTC)Garagepunk66 (talk) 15:29, 7 September 2015 (UTC)
 * in your description of the importance of this article, you mention ecology, weather, infrastructure and history, but I don't see a single word related to geology. This article is at best marginally relevant to our project, hence the importance rating. However, you have done a fine job with the article. If you were to tighten the prose a bit and add more links, I'd be happy to nominate it for a DYK. RockMagnetist(talk) 15:23, 7 September 2015 (UTC)

Graphical Timelines e.g Template:Cenozoic graphical timeline
I noticed that not all graphical timelines don't have a same format. For example Template:Cenozoic graphical timeline is different then all other era graphical timelines, because it is the only era graphical timelines showing epochs. It is a problem to include epochs because the Proterozoic does not have epochs. The Carboniferous timeline shows epochs but most Phanerozoic period templates don't. The Silurian timeline is missing stages/ages.

Which articles should have a geological time navbox?
User:Look2See1 has been adding the Geological history navigation box to many articles, including Hawaiian volcanoes (such as Hualālai), and articles on various extinct taxa (such as Parendotherium). This has been controversial (see User talk:Look2See1).

I'd like to get community consensus -- what sort of articles should use this navbox? What do editors think?

Pinging involved/experienced editors:

—hike395 (talk) 13:42, 30 September 2015 (UTC)


 * Seems there has been massive overuse of the template. The addition to categories such as Category:Neogene Cuba (where it is at the top) is rather absurd. The addition to formation substubs such as Peters Hill Limestone adds nothing except distracting color to a woefully inadequate stub. Rather than adding such a template, a much more productive use of editing talent would be to actually improve and add actual references to such stubs (which appear to have been created by a bot). But its much easier to add distracting templates rather than actually improving an article. Sorry, I'm in a rather grumpy mood this morning :) Vsmith (talk) 14:17, 30 September 2015 (UTC)


 * I dont see the point of adding the template to extinct taxa articles that should have a mini timeline with age in the taxobox already. As an example, it wold make no sense to me to add the template to Yantaromyrmex, given that ages are already linked in the taxobox, the lead, AND the distribution sections.  The template was added to Parendotherium which, though a stub, already has the age linked twice and referenced three times.-- Kev  min  § 14:43, 30 September 2015 (UTC)


 * I agree that including the geologic time scale template on articles not about units of geologic time is excessive. Abyssal (talk) 17:13, 30 September 2015 (UTC)


 * I don't think this template should even exist. Consider this quote from Navigation templates:
 * "The goal is not to cram as many related articles as possible into one space. Ask yourself, does this help the reader in reading up on related topics? Take any two articles in the template. Would a reader really want to go from A to B?"


 * If someone is looking at Zanclean (5.3 - 3.6 Mya), will they suddenly have the urge to go to Rhyacian (2300 - 2050 Mya)? Or even Danian (61.6-66.0 Mya)? Zanclean already has two much more sensible navboxes: Neogene graphical timeline and Neogene Footer (it probably doesn't need both). Going up the scale, Neogene has the same two navboxes and also shares Phanerozoic eon with Cenozoic. Cenozoic also has Cenozoic graphical timeline; in principle, this could also be shared with Neogene. And Phanerozoic has Eons graphical timeline. I don't think there is any article where this template would be useful - not even the main article, Geologic time scale, where there already are tables of time divisions. RockMagnetist(talk) 17:29, 30 September 2015 (UTC)

OK, it seems that the use of this template is quite disfavored in general. Boiling down the choices, we can either:
 * Summary (as of 1 October)
 * 1) Go to WP:TfD and propose deletion of the template (per RockMagnetist), or
 * 2) Put a guideline the template documentation that it should be used on geologic time articles, only. (per Abyssal)

Which path should we take? —hike395 (talk) 11:01, 1 October 2015 (UTC)
 * My choice would be option one, since its redundant to a number of different templates and has no real use.-- Kev min  § 15:46, 1 October 2015 (UTC)
 * I agree; option 1. DanHobley (talk) 16:32, 1 October 2015 (UTC)


 * Sounds like there is a consensus for deletion. you eloquently outlined a case for deletion. Would you make the same argument over at WP:TfD?, ,  what do you think of deletion? —hike395 (talk) 06:18, 3 October 2015 (UTC)
 * I'd be happy to. I'll give the others a little more time to respond, though. RockMagnetist(talk) 06:22, 3 October 2015 (UTC)
 * I call for the template to be deleted.  Volcano guy  09:06, 3 October 2015 (UTC)
 * As it stands, I oppose deletion. I think the template is fine, just over-used. Abyssal (talk) 10:20, 3 October 2015 (UTC)
 * We need a clear criterion for over-use. Would you support removing it from any article that it doesn't link to? RockMagnetist(talk) 15:38, 3 October 2015 (UTC)
 * Basically, or at least geologic time-scale related articles generally. Certainly not random units or in the category namespace. Abyssal (talk) 00:53, 4 October 2015 (UTC)
 * What articles would benefit from it though, all of the articles that are on geologic ages have the larger template in the infobox, all the taxa articles should have the mini timeline in the taxobox, and geologic formations/mountains/etc should also have it in the infobox.-- Kev min  § 15:44, 3 October 2015 (UTC)
 * I think it's appropriate in articles about units of geologic time. Abyssal (talk) 00:53, 4 October 2015 (UTC)

O.k., I think we have consensus for removing the template from pages that are not about time units. We can start with that while we think about the rest. RockMagnetist(talk) 01:00, 4 October 2015 (UTC)
 * I'm working through the articles. This editor even added the time templates to a category! RockMagnetist(talk) 01:22, 4 October 2015 (UTC)

While we're at it, I would say that the same should go for templates such as Phanerozoic eon nav (e.g., in Burgess shale, where the infobox at the top already has a time scale). This same editor has been adding it to a lot of articles. RockMagnetist(talk) 01:03, 4 October 2015 (UTC)
 * I think that deserves a separate discussion -- let's hold off on removing those. —hike395 (talk) 07:25, 4 October 2015 (UTC)
 * I agree in general, but I don't think there is any need to discuss removing article navboxes from category pages. RockMagnetist(talk) 21:13, 4 October 2015 (UTC)

This user has been adding article navboxes to a host of categories - over 750 of them - as well as some redundant information. I could use some help cleaning this up. RockMagnetist(talk) 02:36, 4 October 2015 (UTC)


 * I just used WP:AWB to remove ~400 instances of the template from articles, mostly rock formations and extinct taxa. There's about 1000 left to do (including categories). I'm doing it in batches, so it's less tiring for me and we can check for any further community response to the removal. —hike395 (talk) 07:25, 4 October 2015 (UTC)
 * Thanks for doing that - a much more sensible approach than doing it by hand! RockMagnetist(talk) 21:13, 4 October 2015 (UTC)
 * No problem. I'm done: there are only ~200 transclusions for the template left, all geological time spans (I left the template in about 10-20 categories about geological time spans, just to be conservative). I also updated the documentation for Geological history to reflect our consensus on limiting this template usage. Feel free to edit, if you think I didn't capture the consensus correctly.
 * I would suggest any further discussion on deleting the template take place at WP:TfD, to get wide community involvement. —hike395 (talk) 04:16, 5 October 2015 (UTC)

Navboxes in categories
In all the documentation on navboxes, they are presented as aids to navigation between articles (my emphasis) and alternatives to categories. I can't find any guideline saying they shouldn't be added to category pages, but it doesn't make much sense. I have never seen this done before; it seems to be the idea of one editor. Should we remove the Geology navboxes from all category pages? RockMagnetist(talk) 21:56, 5 October 2015 (UTC)


 * I think that the relevant guideline is WP:BIDIRECTIONAL:
 * Every article that transcludes a given navbox should normally also be included as a link in the navbox so that the navigation is bidirectional.
 * Navboxes are for navigating between a group of related articles. If the category is not in that group, it should (generally) not have that navbox. I'm not proposing adding the categories to each navbox, because a category cannot be an article in a group, nor can it have a See Also section.
 * However, as an exception, I have seen between-category navboxes, e.g., Years in century used in Category:20th century. Phanerozoic eon nav looks like it was designed to be a navbox between categories, but it could be improved for that specific task. —hike395 (talk) 10:57, 6 October 2015 (UTC)


 * Thanks for finding WP:BIDIRECTIONAL; some of the guidelines seemed to imply it, but I wasn't able to find an explicit statement. I don't think Phanerozoic eon nav was intended for navigation between categories; it links to articles while Years in century links to categories and is in Category:Category namespace templates. You created it, what was your intention? RockMagnetist(talk) 14:54, 6 October 2015 (UTC)
 * I made the Phanerozoic eon nav for categories. Abyssal (talk) 14:56, 6 October 2015 (UTC)
 * Right, it does link categories. It seems I managed to persuade myself I'd checked without actually checking. Time for another coffee! So this nav should not be transcluded on article pages. RockMagnetist(talk) 15:48, 6 October 2015 (UTC)
 * If that's the consensus, I can certainly remove Phanerozoic eon nav from articles using AWB. What do other editors think? ( ?) —hike395 (talk) 05:22, 10 October 2015 (UTC)

Apparently there are no objections. I'd do it myself, but installing AWB on my Mac has proved to be very difficult. RockMagnetist(talk) 22:10, 7 November 2015 (UTC)
 * I tend to be conservative about using AWB. Are there any other editors other than myself and RockMagnetist who would support mass removal of Phanerozoic eon nav from article space? ? Bueller? Anyone? —hike395 (talk) 01:27, 8 November 2015 (UTC)
 * I support the removal from article space totally and category space where its not directly relevant.-- Kev min  § 02:14, 8 November 2015 (UTC)
 * Phanerozoic eon nav was the actually useful template. " " was the most widely used irrelevant one. Abyssal (talk) 02:26, 8 November 2015 (UTC)
 * I'm not sure what that answer implies for the question Hike395 asked. RockMagnetist(talk) 02:28, 8 November 2015 (UTC)
 * Oops. Misread it. Yeah, that template only belongs in categories and should be removed elsewhere. Abyssal (talk) 03:09, 8 November 2015 (UTC)
 * ✅ All instances of Phanerozoic eon nav have been removed from article space: the template is now only used for category navigation. —hike395 (talk) 05:23, 8 November 2015 (UTC)

Help with an AfC draft?
I'm going to cut/paste this to three boards, so it'll be the same on each. Long story short, there's an article at AfC entitled Draft:Geophysical signal analysis. It was previously declined as reading like a report/essay, so it could use some help from someone familiar with the topic. It looks like it should be a notable topic, so I just want someone experienced with the topic to ensure that everything is in order (since I am not familiar with this at all). Tokyogirl79 (｡◕‿◕｡)  09:45, 14 November 2015 (UTC)


 * Looks like quite a good chunk of information in there, but it does have a lot of bits that sound like an essay. Encyclopedia's tend to tell you stuff rather than lead you through the though process of getting there. I'm going to carry on on your talk page otherwise this will get very big. EdwardLane (talk) 08:35, 15 November 2015 (UTC)

More time unit templates
Geological period allows users to provide information on periods such as mean atmospheric oxygen and carbon dioxide content, mean surface temperature, and sea level. To see how well this works, check out Cambrian, where the table uses links to Wikipedia files as citations. After looking at those images, particularly File:Sauerstoffgehalt-1000mj.svg, it's hard to see what use an average would be. Is there more appropriate information that could be put in these tables, or are they just a waste of space? RockMagnetist(talk) 18:09, 16 November 2015 (UTC)

Borneo
I just found an orphan Kutai basin which has a good section on the Geology of Borneo - but it could do with some references, and all the sites I hit for sediment thickness or similar seem to be pay walled. I presume some people here already have access to some of these so might be able to supply references? EdwardLane (talk) 06:45, 16 November 2015 (UTC)


 * I've added full access urls for most of the existing refs and I have access to the others. From Chambers et al. 2004 "Rose and Hartono (1978) proposed a sediment thickness of more than 13 km in the Mahakam Delta depocenter, whereas Duval et al. (1992) proposed a maximum thickness of 12 km. Regional gravity modeling (Chambers and Daley, 1995) suggests that 15 km may be a more likely maximum figure for sediment thickness in parts of the basin".

Geologic Ages Inline
The template Geologic Ages Inline is potentially useful for keeping stratigraphic dates up to date, but it has a serious problem: It gives the start of each time unit, not the range. This works for List of Global Boundary Stratotype Sections and Points, but leads to absurdities in articles like Phanerozoic where the lead says "It covers 541.0 ± 1.0 million years". This needs to be fixed right away! Given the name of the template, I'm thinking that it should provide ranges; and if someone wants to do boundaries, there should be a template like Geological boundaries inline. RockMagnetist(talk) 17:34, 16 November 2015 (UTC)

Actually, more intuitive templates, Period start and Period end, exist, so this template is redundant. I'm going to start replacing it. RockMagnetist(talk) 17:39, 16 November 2015 (UTC)

The only thing that might be worth saving/transferring is the Reference field. RockMagnetist(talk) 17:54, 16 November 2015 (UTC)

It has occurred to me that the lead in Phanerozoic can be interpreted in a different way, and my confusion is due to the wording, not the template. My other point stands, though - Geologic Ages Inline is redundant to a better designed template. I am going to list it at TfD. RockMagnetist(talk) 17:12, 17 November 2015 (UTC)

Someone more knowledgeable about WP:BIO can probably do a better job here though. DanHobley (talk) 17:09, 4 December 2015 (UTC)

Globalize tag on Geomorphology
Hi all. There's a globalise tag on this article now.

Load cast

By the way, I created Casting (geology) and Cast (geology) and for the time being, redirected them to Fossil and marked with R with possibilities (and fixed the glossary entry).

Informed opinion needed on Continental drip
Hi all. I'm pretty sure, but not positive, that the subject of Continental drip is a light-hearted joke among geologists and cartographers, not a phenomenon taken seriously.

Impact Field Studies Group
Please check out this article. It seems woefully outdated, the database linked was last touched in 2010 and there is no hint, that the group existed after 2009. I don't find any evidence, that the group ever did scientific work beyond some loose connection between geologists with interest in impacts that were open to look beyond the strict formalities of the Earth Impact Database. They have made some excursions to relevant sites, but I did not find any publications where the group is mentioned. So they might have been mostly educated tourists. Please decide whether this really was a "sicentific organization" and is notable enough for an article. --h-stt !?  16:01, 4 February 2016 (UTC)
 * Share your concern that the group has disbanded, though some poking around confirms it was a legitimate academic grouping until at least ~2010. Broken websites are never a good sign.

Seeking geological information
I was recently in Antarctica and photographed this piece of ice. It was explained to me that it was created in a high-density environment and may be quite "old", based on the details of the ridges (at 100% magnification) and the clarity. Can anyone offer any additional information, or recommend where I might go to find out more? Many thanks in advance.--Godot13 (talk) 04:59, 4 February 2016 (UTC)
 * Not really my expertise, but that looks like a chunk of blue ice, i.e., glacial ice. The bubbles all appear to have annealed out. I suspect this is the main reason for suspecting it's "old" (it's been all the way through the deeper parts of a glacier). Not sure whether "fingerprint" ablation textures really tell you much about age. Sure, it hasn't been pulled out of the ice yesterday, but I don't think you can date with those. The patterning is very reminiscent of a suncup ice ablation texture - which is a classic self-formed pattern in ice and snow, but I think fairly poorly understood in terms of formation mechanism.
 * You also might want to swing by the Blue ice (glacial) page and ask the same question, and also offer this image for their page! It's nice. DanHobley (talk) 19:03, 4 February 2016 (UTC)
 * Many thanks!--Godot13 (talk) 20:11, 4 February 2016 (UTC)

Qattara Depression
An IP has queried the statement in the article Qattara Depression that "The depression was formed by salt weathering and wind erosion working together. First, the salts crumble the depression floor, then the wind blows away the resulting sands." Looking at the source for this statement, it seems to me that the article has followed the source, although the latter did contrast the different processes involved in the western and eastern parts of the depression. Cwmhiraeth (talk) 09:31, 9 February 2016 (UTC)


 * I've modified the text somewhat, mentioning that the depression was initiated by other processes and that the combined salt/wind erosion mechanism is less effective to the east. Mikenorton (talk) 10:18, 9 February 2016 (UTC)

Junction Fault
I've removed this fault from the list of fault zones after failing to find any information about it at all.

Before I propose its deletion, however, I wondered if anyone out there knows more about this? Mikenorton (talk) 10:06, 29 February 2016 (UTC)

Orographic precipitation
I've just discovered we have some issues around orographic precipitation. Small sections discussing it are at Precipitation and Precipitation types, but fuller statements are at Orographic lift (which is a broader topic than just precip, but still) and Orography. Looks to me like the material at Orography is most complete - though under-referenced. However, this is problematic, as the relevant material on that page only kicks in halfway down, and is very easy to miss (and, moreover, in my experience "orography" is a dead term, so it's doubly off-putting to have relevant material at the bottom of a page about a basically obsolete research term).

I think I'd advocate building an actual page for Orographic precipitation, which at present is just a redirect, using the material out of these four pages together. We could then strip it out of Orography entirely, and put actual See Alsos on the relevant subsections elsewhere. I think this would be the clearest way, but wanted a second opinion. I also may not have time to do this any time soon, so if someone else does, have at it. DanHobley (talk) 05:14, 21 March 2016 (UTC)

Addition of stages to Template:Geological History
added more detail to Geological history, see diff. Given our previous discussion about this template, I think the additional details made the template much too crowded. I reverted the additions. I'm bringing it up here to get community input. Comments? Thanks! —hike395 (talk) 02:38, 5 April 2016 (UTC)
 * I agree, the addition made the template massive and beyond use. I still think its a bit too big, and fully redundant to taxobox/geobox templates plus article prose anyway. -- Kev  min  § 03:00, 5 April 2016 (UTC)
 * I second all of the above comments. Of course, I was pushing for deletion in that previous discussion, but was willing to compromise as long as the template was slimmed down a lot. RockMagnetist(talk) 03:23, 5 April 2016 (UTC)
 * Thank you for the above comments - FWIW - viewing a more complete geological history in a single view seems worthy imo - if interested, a more developed version of the "proof of concept"(?) template is "HERE" - in any regards - "my earlier shorter version" seems more accurate - and perhaps more useful - than the "present version" I would think - Comments on this "shorter version" Welcome as well - in any case - Enjoy! :) Drbogdan (talk) 03:36, 5 April 2016 (UTC)
 * Drbogdan, if the purpose of a table of this size is to see geological history in a single view, it shouldn't be a navbox. Navboxes are for navigating between articles. Most readers probably don't even realize they are there, unless they are cluttering up the page. They aren't even displayed on mobile web sites. Those readers who do find the navboxes will be put off by complexity; as the Google search page illustrates, simpler is better. Have a look at the navbox guidelines. RockMagnetist(talk) 04:20, 5 April 2016 (UTC)
 * As has already noted, the point of a navbox is to facilitate moving between related articles.  As I have already noted, with rare exceptions the Geological history template is redundant to taxobox/geobox templates plus article prose anyway, both of which have the benefit of showing in mobile versions of pages.-- Kev  min  § 11:39, 5 April 2016 (UTC)

 * Yes - Thank You *very much* for your comments - they're *greatly* appreciated - my efforts re the "Geological history" templates were fun for me (regardless of their eventual use) - and a learning opportunity (you can learn a lot by editing an encyclopedia) - I've had similar experiences with some of "my earlier mega-templates" (some were eventually used, like the "", "" and "" templates; but others were not used (at least for now), like the "Beethoven" and "Mozart" mega-templates) - in any case - Thanks again for your comments - and - Enjoy! :) Drbogdan (talk) 16:39, 6 April 2016 (UTC)

Category:Categories by geological period
I could use some help renaming this category and its subcats. It is a mess at the moment as "geological period" is being used like it refers to the entire geochronological spectrum when in reality it only refers to a subdivison of an era. What would be the correct title?  Volcano guy  05:56, 29 April 2016 (UTC)


 * The problem is the word period is probably meant to connote span of time but, as you note, it is also a name in the formal geochronological system. Maybe Category:Categories by geological time span That would allow flexibility as needed. Then the subcats would be Category:Impact craters on Earth by geological time span, Category:Prehistoric life by geological time span, and (for consistency) Category:Volcanism by geological time span. And you or someone else can probably come up with something less clunky than time span. Just plain time? Age? — Gorthian (talk) 20:10, 29 April 2016 (UTC)

So far I've set up the draft as a summary of the stratigraphy of the country and a brief section on mining, which obviously needs to be expanded. Roger (Dodger67) (talk) 19:44, 2 May 2016 (UTC)


 * BTW - When describing the stratigraphy do I start at the bottom or the top? Roger (Dodger67) (talk) 06:48, 3 May 2016 (UTC)


 * It would be normal to begin with the oldest. Mikenorton (talk) 07:28, 3 May 2016 (UTC)


 * Thanks Mikenorton, would you mind taking a look at the draft to check that I'm on the right track. Roger (Dodger67) (talk) 11:36, 5 May 2016 (UTC)


 * I will be away from home and with only very intermittent internet access for the next week (I'm not comfortable with doing much editing just from my smartphone), but I will try to take a look once I get back. Mikenorton (talk) 23:45, 5 May 2016 (UTC)


 * I think we need draft page Geology of Continent. There should be some system in making pages of different geology of Continet. Continental crust pieces are formed at one point→ Craton formation and since then they have additions through orogens and then they are broken and rifted apart. They maybe dont grow in total, but their history has been growing last 4,5 Ma. So because every continent has craton, every continent has these rocks in it's "core". Craton made of TTG's special rocks which are actually the oldest rocks on earth, they formed only in early history of earth. I will reference that.... I have been lucky to hear lecture from prof Steve Foley who is one of the leading scientist in field. Have even lecture ppt with all the reference and pictures.... So geology of the continet is in my view history of continetal crust piece.... I unfortunately cant help with stratigraphy.  By the way impressive work! and sorry I am kind of tired, this sis not draft for Geology Of Africa but south Africa, but still there should be craton (: Obradow (talk) 14:35, 27 May 2016 (UTC)

Tufa
You do not appear to have a peer review for photos so forgive me for posting this here. Etan J. Tal recently asked this question on Ref Desk: Reference desk/Archives/Science/2016 April 30. I think its probably tufa. If so, he has asked me me on my talk page as to what would be a proper description with which to caption his photograph? Tufa is quite common if one only looks – so he and I'm thinking it might be a worthy example to include on the tufa article. Any thoughts?--Aspro (talk) 14:53, 3 May 2016 (UTC)


 * I am far from being an expert, but "tar-like consistency" would imply to me that the stuff is still forming; it hasn't yet become tufa (which, though often soft or fragile, is a rock). Perhaps in the lithification process, the blackness would leach out of it, since black tufa would be pretty unusual. That's a striking picture—I definitely would not want to wade in it! ;-) — Gorthian (talk) 01:39, 6 May 2016 (UTC)
 * Aspro, I edited your link so that the discussion can be found now that it's in the archives.


 * Yes, I have to agree with Gorthian that it not tufa yet. To use you to bounce-ideas-off again.  I don't think proto-tufa is a recognized term, yet this black stuff may have the potential to become it. This why I can't think of a geological caption for the photograph. Perhaps after the existing caption of  A spring stream near Arakhveti, Road E117 / S3 (Georgian Military Highway) (Georgia (country)) . Orange colour is caused possibly by iron, this could be added Note: The black calcite deposits around the margin of this  spring, which may  lead to the formation of tufa if it becomes cemented over time. We are going from a photograph here,  and so  it is only my guess that this  is calcite deposits. But on the balance of probabilities I can't think of a better explanation. So I think at the moment it seem a good example of how tufa forms but am at a loss to know how to correctly describe the photograph. I think it would be useful for the tufa article because around the margins of tufa lakes this black stuff can be seen just as Etan J. Tal describes it.--Aspro (talk) 12:59, 6 May 2016 (UTC)


 * It a appears that from a photograph alone, no one is willing to guess at it (which I half expected, and  why I posted it here, in the hope of  more informed  opinions). The black goo could equally be the result of bacteria sequestering  manganese out of the water. As the clumps of such bacteria are not strong enough to resist flowing water they  won't appear in the main flow of the spring. If however, manganese is the culprit, it would create rarer black tuffa. Without an analysis, I think the closest we can get to can this transform into tuffa  is: perhaps and maybe. Still think though, it is a good image of contemporary geology in the making and in the flux of change but I will leave the image description as it is.--Aspro (talk) 19:34, 29 May 2016 (UTC)
