Proposal To Start Automatively Archiving Discussions for this Talk Page - It is Getting Too Long

edit

I propose that we start automatically archiving discussions on this talk page. It is getting unwieldy and too long to have discussions on it. I would do it. However, I have never been able to set automatic archiving up the times that I tried on oethr pages. Paul H. (talk) 01:08, 20 June 2023 (UTC)Reply

Hopefully the MiszaBot setup on the page will now work, once there are more than 4 threads. – SJ + 02:00, 14 October 2023 (UTC)Reply

Richat Structure

edit

Richat Structure is an actual Structure within the geological formation known as the "Eye of Sahara", not the actual geological formation itself. Dating the soil beneath is not accurate at determining age.. Sumerians describe "Eye of Sahara" as a secondary asteroid impact(a "RicAchet" Latin O~A) before landing beside Ethiopia with both African impacts being the cause for both younger dryas sediment layers as well as glass fields in Egypt & Libya.

Looking at the sources and explanations already provided within this very article, I do believe you have been misinformed. --Licks-rocks (talk) 14:57, 24 July 2023 (UTC)Reply
In my opinion, you are flogging a dead horse because you appear to be discussing original research that lacks notability and vertifiable secondary sources. As a start, you need to get your ideas published in a reputable source such that other people, who judge them significant, can evaluate and comment on it in the scientific literature. In addition, Wikipedia is not a forum for promoting your own personal research. Paul H. (talk) 16:08, 24 July 2023 (UTC)Reply

Air burst

edit

Is there a possibility that this was formed from an air burst? If the material was fresh enough after an eruption, and an air burst happened close enough to the surface it could explain the shape, contents, and close proximity to the crater formed near by. 2603:7080:6A40:2E00:D4C6:4407:6FCA:3197 (talk) 23:26, 20 October 2024 (UTC)Reply

The original surface overlying the Richat Structure has been destroyed by erosion over many millions of years. Any crater, volcanic or otherwise, was destroyed by erosion long ago. I would not be surprise if the rocks exposed at the surface now were a kilometer more or so below the surface at the time the Richat Structure was formed. I will have to look if anyone has either conducted any geothermobarometry work at or near this structure or otherwise the burial depth of these rock. A recent, open access, paper is:
