Abstract
ABSTRACT Alain Person, Nour E. Saoudi, Sylvie Amblard The preliminary results of a field campaign performed in January-February 1994 on the environment of the archaeological settlements in the Dhars Tichitt and Oualata region (South-eastern Mauritania) are presented here from a methodological point of view. The sedimentary faciès are interpreted mainly in terms of climatic changes linked to the human settlements. It seems that the most important phase of peopling is not correlated to a climatic optimum. On the contrary, this phase is contemporaneous to the most precarious period. Indeed, at this time, the exceptional morphological features of the Dhars offered a refuge area in the Southern Sahara between 2,500 and 3,500 B.P.
