Karst pockets of the paleoshores of the Rabat-Témara coast (Morocco) : age and mode of formation
Résumé
Karst pockets of the Rabat-Temara coastal area (northwestern Morocco) contain archeosedimentary in filling covering the entire Upper Pleistocene and Holocene. Thus, they have key role in researches focusing on North African Prehistory, due to their archaeological and palaeoenvironmental records.
These cavities are known to be caves dug by the ouljien sea in calcarenite (marine and/or eolian) of Middle Pleistocene age. In light of observations on several recent and fossil caves, we discuss the formation mechanisms as well as the chronology of the shaping process, the morphology and the evolution of cave systems. We also describe the sedimentary deposits of these coastal caves according to the different stages of deposit.
