Les paléo-rivages des formations littorales atlantiques du Pléistocène moyen - supérieur de Rabat-Témara (Maroc)

The lithological and sequential analysis of the deposits constituting the second coastal ridge of the Rabat-Témara shows that the second coastal ridge is polycyclic and composed of three superimposed or nested regressive sequences. A detailed discussion of the age of these sequences and their relation to eustatic variations is based on radiometric dating on this second ridge as well as on the first ridge and on the prehistoric caves infilling. The identified sequences reflect a progradation of a coastal prism, with evolution of deposits from a marine context towards a continental context. The first sequence is formed during the isotopic stages MIS9 to MIS11. The second sequence is deposited during the isotopic stage MIS7 and the edification of its summit could continue during the MIS6. The third and final sequence is formed during the MIS5.
