Croûtes calcaires quaternaires du piémont nord des Aurès (Algérie)

Abstract : Two Quaternary pediments on marl, that of Moulouyan age (Lower Quaternary) and that of Amirian age (Middle Quaternary) are capped by calcretes of different types. Thin slide observation evidentiates : - their palustrine-lacustrine genesis, which is a sign of subsident basins, say a topography different from the actual one, - the existence of arid phases with aeolian activity at the end of respectively the Moulouyan and the Amirian
