Mauritania: More is known about what the Richat Structure is not rather than what it is. It is not an impact crater, it has no raised central peak and no presence of shock-altered minerals. The approximately 50 km diameter circular feature did not form from a volcanic eruption because there is no presence of igneous rocks. The Richat Structure is thought to have been caused by uplift and its appearance is due to erosion from wind and water.
