Variations de l'environnement et industries préhistoriques au Pléistocène supérieur terminal au Maghreb oriental pré-saharien

Abstract : Compiling of bibliographic data has been completed with unpublished data and personal field research. They tend towards the evidence that Upper Pleistocene climatic fluctuations in Lower Sahara are contemporary with the temperate Europe ones and having the same characteristics. Pleniglacial (22 000 B.P. - 14 000 B.P.) is very arid, more arid that at the present time. Deflation dug into the Tunisian Grands Chotts. Then aeolian sands accumulated (Gafsa and Bir Ou Ali region, Matmata plateau, El-Haouita, Bou Saâda, Grand Erg Oriental third generation) even on the seaside (Tlêt formation) where a main marine regression occured. Bladelets industry makers settled down in some of these eolian accumulations. During Late Glacial (14 000 B.P. - 10 000 B.P.), temperate Europe type climatic fluctuations very probably occured. Bladelets industries persist up to about 10 000 B.P. while first Capsian industries are appearing.
