Thread: A crazy question about the Richat structure

Just on a mad one here, but what if the Richat structure (About 11000 years ago) became an outlet for the remains of the Tethys sea? If there are or were massive aquifers underneath the Sahara - the remains of the Tethys sea, could the African humidity period have been caused by the up welling of gases from this area due to the pressure build up by the higher ground level sitting to the east?

Go easy. I'm not a geologist. (-;

The timing is off.

The Tethys Sea dates from 600 mya to 250 mya. The Richat structure has been dated to 98.2 ± 2.6 mya.

Besides which, the Tethys Sea disappeared because of plate tectonics. It was pushed aside -- not overriden by -- the African continent. There is an aquifer, the NWSAS underneath Algeria, Tunisia and Libya. However the Richat structure is in Mauritania, 2700 km SW of the North Western Sahara Aquifer System.

Richat Structure is a geological formation in the Maur Adrar Desert in the African country of Mauritania. Although it resembles an impact crater, the Richat Structure formed when a volcanic dome hardened and gradually eroded, exposing the onion-like layers of rock.

Any moron can Google then cut and paste. Try to have an original thought...
