Quartzite crests in Paleoproterozoic granites (Anti-Atlas, Morocco); a hint to Pan-African deformation of the West African Craton margin

South of the Pan-African suture zone of the Anti-Atlas, the Agadir Melloul inlier exhibits several crests of nearly vertical conglomeratic quartzite beds inserted in Paleoproterozoic granites. These enigmatic rocky walls have been considered as Early Neoproterozoic platform sediments pinched within the 2.03 Ga-old granites during brittle faulting events at ca. 570 Ma. The data presented here contradict this interpretation. The quartzite crests...
