Morphogenèse et préhistoire dans les Aurès (Algérie)

Abstract : Recent researching in the Aurès mountains has allowed the discovery of 43 new prehistoric sites; from this, different stages of quaternary morphogenesis may be dated with greater precision. Thus, level VI (Morocco Moulouyan ?) slightly successed Lower Acheulean and pediment III (Morocco Tensiftian ?) is prior to Upper Paleolithic. Terrace I came after Capsien; in particular, its summit is constituted by deposits derived from a post-Neolithic soil erosion. The study of prehistoric tools shows that efficient eolisation and gelifraction occured between Upper Paleolithic and Epipaleolithic. Since Middle Paleolithic, the formation of calcareous crusts moves northwards. On the other hand, the southern cortex enriched with metallic oxides and the northern cacholong went on forming at least as far as Neolithic.
