Alexander's Peer Review: Skarn

I would like to begin by complimenting the draft on its abundant sources and attention to the petrogensis and general geology of Skarns as there appears to be a lot of good concrete information. Additionally, it is very beneficial that you have a good understanding of the present work done on the skarn article and have described how you will integrate your work to it as opposed to deleting all the present work and adding in only research done by you. However I do believe that sentence structure could be slightly improved upon. As a reader it can be sometimes be difficult to follow and I would much prefer a "flow" to the sentences so that choppiest can be kept to a minimum. Also when it comes to finalizing your draft, adding on a diagram or image would be very beneficial to visually see how skarns are emplaced. I would also sometimmes follow up with existing ideas or topics. For example, "Skarn is formed by a variety of metasomatic processes during metamorphism between two adjacent lithologic units. Skarn can form in almost any lithology type such as shale, granite and basalt but the majority of skarns are found in lithology containing a limestone or a dolostone. It is common to find skarns near plutons, along faults and major shear zones, in shallow geothermal systems, and on the bottom of the sea floor (Meinert, 1992). The mineralogy of skarn is highly related to the protolith." The information given is very broad which is as you mention it "can form in almost any lithology" however expanding on various lithological units and comparing the differences in each geologic setting would be insightful. In general could be beneficial to focus on an idea and expand on it which would demonstrate the quality over quantity argument.

The writer does not expand on any irrelevant ideas associated with Skarns and is neutral as there does not seem to be a bias leading more particular one way. Further geological characteristics can be developed and added onto topics such as physical and mechanical properties, deposits, fluid controls, mechanisms, history. However due to the scope of the project, the length is substantial.

Current citations are good and are from reliable sources however a little out of date (there is nothing from this century!). Some key sentences do not have any intext citations, therefore some sentences require additional citations. Best to cite everything so that we know exactly where you got the information and can return to the original source and take a look at any possible irregularities in their work. Especially important if the work done is out of date.

The article's talk page I think could be more utilized as there is nothing added on. Addition of ideas could be added so that others can also have input onto what you are writing. Could be potentially useful especially during the final stages of editing your draft and expanding of points of not just the peer-reviewed aspect from classmates but from anyone. In the talk page, the article has been rated as a start page on the quality scale and of low importance on the importance scale, however I'm confident that after additional editing from Lukasz and his partner the article will be far more informative that what is currently present.

Peer Review 2
-Everything is relevant to the topic. It is especially wise to remove any information you find unnecessary, such as the "or tactites" phrase and redundant paragraphs.

-The use of multiple resources is very good, but the page could benefit from more current articles.

-Finding a photo of one of the ore deposits could add some value, possibly one of the mining sites listed.

-Under classification, it may be helpful to find or create a chart that distinguishes the different types of skarn. If this is unreasonable, a few photos of some of the examples may be useful to the reader.

-Overall you've done a great job at presenting the information in an easy to understand manner. A few charts and more recent links could go a long way.

Peer Review 3
- First thing I would like to mention is article overall is really well done. Very informative, written in a way that neutrality is clearly shown. and there are numerous sources making the article very well rounded and not bias in the slightest. - Like the first two reviewers have mentioned, the usage of more recent articles might help strengthen your article, as it helps to relate things more to the present than to the past, as you guys know information changes all the time. I did read your notice at the top about finding only summaries that are current and touch on Skarns, and possible journal articles that use the sources you guys currently. However it is possible these articles could have expanded or even discovered information on Skarn, that could have changed the understandings of it. Nonetheless, new articles are written everyday, so might not hurt check google scholar or other academic search sites for new sources. - Another point I would like to mention is have you considered grouping classification with ore deposits? As a reader, I think it would be more insightful to understand which skarns produce what metals based on their characteristics or in which deposits they form. - Same a peer review 1, I did find the sentence structure, and the set up of the draft to be confusing, those I believe that can be changed up during the expanding part of the assignment. - Just as the other peer reviewers mentioned, charts may also help make things easier to establish differences between the types of skarn, and would help people who are more visual learners to understand better.

Respond to the peer reviews

- The geological characteristics of physical and mechanical properties, deposits and mechanisms are explained in the Petrology, Formation and Ore deposits sections. The fluid controls are very broad which depends on the locality, geology and composition of fluids. For history, it is already in the original article in the Etymology section.

- The two images of skarn hand samples are added with descriptions. It is hard to find the diagrams without conflicting with the copyright rules.

- The tectonic setting, their host rocks and ore minerals of two skarn deposit types (Fe and Cu skarn deposits, which are two possible examples of many possible ore deposits associated with a tectonic setting) are added which are from the recently published papers.

- We added two recently published papers talking about specific deposits.
