Les conglomérats du P III (Néoprotérozoïque supérieur) de l'Anti Atlas (Sud du Maroc): molasses panafricaines, ou marqueurs d'un rifting fini-protérozoïque?
Abstract
By their petrographic and sedimentary characters, the detrital rocks of the PIII (Late Proterozoic) studied in the Anti Atlas (southern Morocco) suggest that their deposition was controlled by normal faults. These faults were active several tens of My after the Moroccan Panafrican deformation. They are the markers of a rifting episode that is indicated on the other hand by magnatic activity, calkaline, theolitic then alkaline, at the Proterozoic-Cambrian limit.
