L’enregistrement tardiglaciaire de Dourges (Nord de la France, bassin de la Deûle) : évolution d’une zone lacustre et gisements archéologiques associés

Abstract : A dip in the Deûle valley, bottom the chalky slope of the Gohelle country (Lens mining basin), has yielded Late Glacial deposits with palaeontological remains and archaeological artifacts. The nature of the deposits appears linked to humidity variations. A lacustrine episode dated from the Bølling is characterized by the development of an aquatic biocoenosis (fish and mollusks). A fragment of a Magdalenian harpoon and the remains of a large wild ox were discovered in the lacustrine tufa. The Older Dryas corresponds to dry conditions and a stratigraphic hiatus. After a new increase in hydrological conditions (short floodings), the area turns marshy again during the Allerød. FEDERMESSER hunters are represented by assegai, barbed bone points and arrow points. The end of the Allerød corresponds to a return to dry conditions and the formation of humic soil. During the Younger Dryas the cooling provokes slope erosion and the filling up of the hollow by silt colluvium. An elk skull was discovered at the base of this last deposit.
