The Richat Dome is a huge circular, slightly elliptical depression (~ 40 km in diameter) in the Proterozoic to Cambro-Ordovician sedimentary series of the NE part of the Mauritanian Taoudeni basin. This structure consists of a central zone that corre

In northwestern Meseta, the Sidi-Said Maâchou volcanic complex includes dykes, sills and basaltic flows. This volcanism is synchronous with a Paradoxides schist deposit. Most of the rocks have been affected by post-magmatic alteration processes, whi
