Good work! 1. On the Tectonic setting section, the first three lines could make starting statement for the section because it directly stated the reasons for relating TTG formation with tectonic origin. It can be followed with the geochemical characteristics that you started with.

2. Under the continental arc TTG section, the rock was related to subduction. Since subduction was first mention there and it is fundamental to their formation, I think you should either add an hyperlink or provide a concise definition of the term or both.

Feedback from Michelle

1. In the Non-Plate Tectonic Setting section, seems that it can be sub-divided into delamination induced TTG and underplating induced TTG. You may consider adding two sub-headings below the Non-Plate Tectonic Setting section to divide the paragraphs instead of a bulk text.

2. You have scale of depth for the Archean hot subduction hypothesis, it maybe great to have scale of depth for the diagram showing delamination and underplating.

3. Why TTG can be found in ophiolite? I think it would be great to have one to two sentences explaining this. — Preceding unsigned comment added by Myip003 (talk • contribs) 15:09, 19 November 2018 (UTC)[reply]

Modern TTG suites

TTG suites at the present day are produced within subduction systems where a spreading ridge is undergoing subduction, such as the Chile ridge and the South American subduction zone. This means an analogy between ridge/hotter than normal ocean crust and the process of Archaean tectonics can be made. ClimberDave 15:54, 17 April 2007 (UTC)[reply]

Feedback from volcanoman7

I note there has been a recent reference added to the page. The reference is - Archean continental crust formed by magma hybridization and voluminous partial melting. The paper was recently published and I wonder if it is just an author trying to insert their paper to get attention. The ideas in the paper do not strike me as anything new or distinguishing. My suggest would be to remove the reference and see how the paper gets referenced in the future. Volcanoman7 (talk) 02:38, 17 November 2022 (UTC)[reply]
