Talk:Subduction polarity reversal

Review from Jeffrey

Hi Vincent! This is Jeffrey your regional geology classmate. I really like the topic of your page and have a few suggestions for improvement of the page:

1. I suggest labeling the plate names in english and point out the occurrence of subduction reversal in the world map (it is not indicated although it was mentioned in the caption)

2. In the lithospheric break-up model, i think more explanation on how the rotation of the frontal block of overriding plate results in a new subduction direction is needed. It would make understanding the model much easier.

3. The last diagram of is a bit messed up as the words are misplaced and overlap with each other. It is probably not your problem but a problem resulting from the export of the original file. It seems to be ok in preview(but the words are too small), but messed up when click into the file to get a full view.

4. It would better for readers if the legends are shown in all the stages(diagrams) of the gifs you made, i.e. not just shown in the first stage(diagram) as one diagram only lasts for 1-2 seconds, which make us hard to read.

Cheers!

Jeffrey

Suggestions from Beth

Hi Vincent, I think your page is really interesting with great diagrams and good approach to explaining the models that make it easy to understand. There are a few things that I think you should adjust:

1) The start could be better if you say your topic and clear outline in the opening sentence, maybe you could combine the first few sentences. I read here... https://en.wikipedia.org/wiki/Wikipedia:Writing_better_articles ...that the first sentence should say what it is and give a good overview.

2) The section on Geological Distribution needs a look over the sentences. Also in other places the sentence structure could be a bit clearer.

3) For some of the models of Taiwan could you make the key and arrow last longer so people can see what is what more easily.

4) Some areas could be expanded a bit more to make it clearer. Like the model section you could say why Taiwan gives such a good overview of all the stages, in the progressive tearing section relate the Laurentian Margin example to the closure of the Iapetus ocean to help people place it in geological time and for the models section am I right in thinking that you give 3 ways in which the subduction polarity flipping occurs - maybe these could have a clearer introduction.

I liked reading it!

Review from Skylar

Hello Vincent! Skylar from your class =] I have not read much about this topic and it is attracting reading your page, especially the diagrams. Here are some comments for you.

1. Very nice diagrams and animations show clearly the cross-sections and the mechanism of models. The models become easy to understand with help of animations. The map also helps understanding the positions of each cross section very well. For animations, the legends and the labelling should appear in each slide but not only the first slide, so that readers can keep track of what is each part throughout the animation. The descripting paragraphs can be improved by adding notes stating each sentence or sentences are referring to which slide. The animations and cross-sections may need amendments on the font sizes and image sizes, since they are quite hard to read without enlarging the images. And it seems the cross-section image cannot be enlarged.

2. For the models, the parts show clearly the geometry and mechanism of the systems, but there is few explanation of the kinematics of the systems. I think explanation can be added to explain why a certain model happens in a certain place, like providing some brief descriptions on the regional tectonic, the evidence to support such models and what have happened after the flipping.

3. The flow of contents is generally easy to follow. I think the first part of the page should be moved to the Taiwan’s example part. The first of a page should be something that provide a glimpse of what subduction polarity flipping is about, like in the introduction part, rather than a paragraph for saying why the flipping is interesting. Moreover, more detailed description might be provided for explaining the geometry of the flipping, like using simple diagrams, since readers need to know what exactly is flipping before knowing the models.

Add oil =]

review from Jennifer

Hi Vincent! Here are some suggestions for minor changes:

1. Make good use of Wiki "bulleted list" function, rather than using "-" in the Examples of location of subduction polarity reversal.
2. The gifs in slab breaks off and double convergence model, it's a bit hard to follow as the lines in each frame are not in place with the previous frame. I think you can compare them to the Lithosphere break-up gif which is much easy to follow, and fix the other two.
3. Cut the blank space in gifs.
4. Seems like the Taiwan part is an example of Slab break-off model only. You might want to mention that clearly in the title/text. However, if there is any alternative interpretations of Taiwan subduction reversal (the other two models) mentioned in other papers, you might keep the title and explain a bit.

Review from Cloud

Hey Vincent, I like your use in animated diagrams in your page and I think your topic is very intriguing. Here are some suggestions for your page:

1. I think you can make the later-brought passive margin (continental crust?) a bit thicker so that it is more on scale.
2. For the second model (Double convergence model), actually I don't quite understand the accommodation of new slab, why is there a strike-slip motion? I think you can elaborate more on the strike-slip part? Is there only part of the crust being laterally moved or if the whole plate is also moving? I am really interested.
3. I agree with Jennifer that you may also want to illustrate other models with real-life sample apart from Taiwan (e.g. Eurasian - Philippine Plate subduction and Alpine and Apennine subduction )

Keep up with the good work :D.Cloudnstars (talk) 12:26, 22 November 2016 (UTC)

Review from Wayne

Hi Vincent, I have read the page. I am able to understand the basic idea of Subduction Polarity Change, which is a good thing. Yet a few things can be polished so that the page would be better.

1. The page seems used a lot of words like "people, geologist". It seems involving a lot of people but who are they actually. Who is the one suggesting the model? It might be helpful to trace the idea of that scientist if his/her name is mentioned in the article.
2. The format of the last diagram is a bit hard to follow. Might be it is the wikipedia's problem but still try to fix it so that readers can be easier to read.
3. Avoid some subjective description, as it is an informative page, try to state something factualemotional sentence should not be included.
