Abstract

The evolution of the Oued es Seffaia alluvial fan during the last 50,000 years is analyzed in the light of chronometric data deived from AMS radiocarbon and optical dating techniques. These ages have enabled the temporal constraint of the distalward progression of the intersection point (the upper limit of the locus of deposition) which has resulted in the telescopic segmentation of the fan. The data provide some evidence to suggest that fan incision and formation of telescopic segments occurs in response to changes from arid to less arid conditions
