Mystery of the Giant Eye - Richat Structure AFRIC

The so-called 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 some theorized that it formed due to an asteroid strike, but this theory has been ridiculed and suggested that the actual reason behind the formation of the Richat Structure is a volcanic eruption. And due to the lack of evidence of any igneous rock in that place, this theory too didn't seem to work Tenoumer and Temimichat. As noted in Woolley (2001)'s summary and review of its geology, various previous studies have found exposed igneous dikes and carbonatite necks, which are incompatible with an impact origin but perfectly compatible with an underlying igneous intrusion having formed this structure, cutting across the strata of the Richat Dome
