Origine du remplissage sédimentaire des grottes de Témara (Maroc) d’après l’étude des minéraux lourds et l’étude exoscopique des grains de quartz
Abstracts
Quaternary deposits of the areas of Rabat and Casablanca (Morocco) have been intensively investigated. We focus here on depositional sequences from the caves of El Mnasra (Casino), Ouled Bouchikha (Les Contrebandiers) and El Harhoura II in the area of Témara. The sequences are correlated with isotopic stages 3 and 2. Exoscopic study under ESEM (Environmental Scanning Electron Microscope) of quartz grains selected throughout the different sequences has helped to describe sediment transport processes. Sediments originating from various areas of the Moroccan Meseta and Middle Atlas, were carried by wind and river transport, and then deposited along the coastal continental shelf. They followed there a complex evolutionary process before completing their transport which ended in the Témara caves.
