Richat Structure in Mauritania

The Richat Struc­ture in Mau­ri­ta­nia. Through vol­canic ac­tiv­i­ty, sed­i­ment lay­ers from the primeval ocean were pushed to the sur­face in the Maur Adrar Desert. Sa­ha­ran winds erod­ed these over time, trans­form­ing the dif­fer­ent lay­ers of hard rock in­tru­sions in­to con­cen­tric rings and dips. The dis­tinc­tive for­ma­tion is a land­mark for as­tro­nauts.

The Richat Structure in Mauritania. Through volcanic activity, sediment layers from the primeval ocean were pushed to the surface in the Maur Adrar Desert. Saharan winds eroded these over time, transforming the different layers of hard rock intrusions into concentric rings and dips. The distinctive formation is a landmark for astronauts.
