Les formations fluviatiles quaternaires de la plaine de Doukkala (Méséta occidentale marocaine), Sédimentologie et nouvelles données chronostratigraphiques

Abstract

Key words: Quaternary; Meseta; Sedimentology; Chronostratigraphy. The Quaternary fluvial formations of the Doukkala plain are, until now, slightly studied. Our study has allowed to precise that the fluvial terraces of the oued "the Oum Rbia oued", are clearly distinguished from the secondary oueds terraces by the dynamic deposit of the alluvial materials. Moreover, the mammal fossils recolted from some of these terraces allow to review the ages attributed by Gigout (1951).
