Talk:Optically stimulated luminescence thermochronometry

My Personal Feedback
1. I did a general rewriting of the entire page after receiving feedback from the first draft. The feedback helped me to improved the page.

2. To Mitchell, thanks for your observations, I actually provided a simplified OSL detective system sketch but most likely that Graeme removed it. When I checked the image in my folder, I discovered a slight label error. May be this is a reason for that. I have corrected this and hope to contact Graeme before adding it back to the page.BlessingAdeoti (talk) 00:30, 20 November 2018 (UTC)

1. The structures are clear and the concepts are clearly explained. It would be great to have a photo showing the experimental apparatus for OSL dating (if any), or a simple schematic diagram to show the OSL signal detection system.

2. For the sentence “where Nis number of accumulated electrons, pis the filling rate, tis the time (a)”, you may add spacing after each variable.

3. In the last sentence of the sample preparation section, “…..that can contaminate OSL signal are removed by etching in HF”, you may use the word hydrofluoric acid instead of HF. — Preceding unsigned comment added by Myip003 (talk • contribs) 14:28, 19 November 2018 (UTC)

This version is much better than the last one! Here are my further suggestions: — Preceding unsigned comment added by Adayding (talk • contribs) 04:19, 21 November 2018 (UTC)

1. "As they cool, they trap electron charges, which are accommodated within crystallographic defects or vacancies in their crystal lattices until the closure temperature is attained." Probably trap electrons after they pass the closure temperature?

2. In the OSL age determination section, it will be better if you tell the audience how to calculate the age first, and then demonstrate the dose and dose rate determination.

3. In term of the dose rate determination, do we neglect the radiation emitted by other mineral grains in the bulk rock?

= Feedback from Giovanni = Well structured page. Some suggestions:

1. Break down your section text into short paragraphs, too long and this may cause the reader to lose interest.

2. Application section could be expanded and better represented.

3. Dose rate equation could be explained by simply showing it in the formula, this way you can visualize it instead of using additional text.

= Feedback from Jupiter =

Here are some suggestions for your page:

1. Your paragraphs are long, and each section only has one long paragraph. You may want to break them into shorter paragraphs.

2. Enlarge your diagrams. The text in your first one about tectonic and erosion of overlying rock unit is unreadable on the page.

3. Also, for the first diagram about tectonic and erosion of overlying rock unit, why is the mantle layer and the layer above the detachment fault sharing the same colour? It may be better to use a different colour for different parts.

Hi Blessing, these are some suggestions for your page:


 * This page is well organized, but It's a little hard to understand for me because there are many physics’ concepts within one long sentence.


 * In the first equation, "saturation age" is represented as "As", but it is "Aa" in the explanation, are they the same?

Feedback from Anyang
Hi Blessing, here are my suggestions:

1. In the first graph, you try to illustrate that surface erosion (of the orange part) aids exhumation (of the grey part), which means that the second figure in this graph should be earlier in time. I suppose that it will be easier to understand if you change the order of the two figures in this graph.

2. By saying "a low temperature-dependent process", do you mean a SLOW temperature-dependent process? The word "low" is misleading.

3. The physics of the processes and the mechanism of the method are well demonstrated in the page "Luminescence dating" and "Optically stimulated luminescence (physics)". I supposed your page should focus more on geological aspects, e.g. in which situations we can use the method and what can be inferred from the results. Solid examples of geological applications may serve your demonstration better.

4. The assumptions on dose rate correspondent to different geological scenarios should vary. E.g. Dose rate of fluvial sediments is different from that of aeolian deposits or minerals in rocks. The dose rate used in studies thus may influence the resulting age to a large extent. You may want to discuss it more.

Hope you find them useful.

It has a good structure that covers basically every aspects of this topic. The concepts in this article are understandable for the audience who might be interested in this kind of topic.

There are several grammar and phrasing problems in this article. For example, in the last section, there are two paragraphs that have the first three sentences identical; also in the last section, there is an typo like "t(10km he". Similar errors ocurr in the other places, make this article although well structured, but needs more editing in sentences.

The last image is a cross-sectional evolutionary diagram trying to explain the application of OSL. I found this image cannot serve this purpose well enough because it lacks the geothermal gradient that should represent the closure temperatures of OSL dating methods, such that the audience cannot figure out which part of the cross section can be applied with OSL dating, and what are the potential results. A way to update this figure is following the style of thermochronology excercises.

It is a good knowledge acquiring and updating process for me while trying to communicate the topic to the rest of the world - of much particular interest, the Earth Sciences. Also having to keep my communication as simple and meaningful without distorting the true meaning of the subject matter is an act I appreciate in doing this task - But I guess I have not really done it pretty good yet.

To a great extent, having to apply the basic skills in the Regional Geology Course has opened up my need to always conceptualize every points, hypotheses and conclusions made in any journal or scientific papers. The Regional Geology class is extra productive - particularly the incorporation of Wikipedia project into it. It gives the students the skills needed in solving diverse regional geological problems. At the same time, these skills are almost immediately encouraged to service a voluntary educational cause. Although it is demanding but I really love the idea. — Preceding unsigned comment added by BlessingAdeoti (talk • contribs) 03:46, 23 October 2018 (UTC)
