Abstract: | This paper reports on results from survey and preliminary test excavations at MSA and LSA sites along the Songwe River in the Lake Rukwa Rift Valley of southwestern Tanzania. At IdIu22, a continuous, extensive archaeological deposit was revealed which may have both Pleistocene and Holocene components. The lithic material here shows a gradual transformation from a flake based LSA assemblage to one employing microburin techniques.Cet article discute la recherche préhistorique aux environs de la rivière Songwe, dans le vallée rift de Lac Rukwa en la sud-ouest de Tanzanie. Au gisement IdIu22, un sequence de l'âge de la pierre finale (LSA) a été découverte avec possible niveaux du Pleistocene et Holocène. Les assemblages lithiques changent graduellement dès un LSA avec outils sur les éclats, vers un LSA employant la téchnique microburin. |
