L’évolution de la vallée de la Marque dans le secteur de Bouvines (Nord, 59) depuis la fin du Pléniglacaire Weicshelien

Abstract : As part of a regional research program (UMR 8164 HALMA-IPEL, Université Lille 3) aiming at developing our knowledge of the anthroposystems of the Deûle basin, geomorphological investigations have been carried out along a stretch of the tributary valley of the Marque, in the Bouvines area. About twenty screw-auger probing excavations have enabled the stratigraphic sequence to be established for the quaternary deposits filling the bottom of the valley and to reconstruct locally their paleogeographic evolution, as their chronology could be established with more accuracy through four radiocarbon datings. The interpretation considers the deposit through the action of wind and river of an alluvial layer under the periglacial conditions attributed to the Weichselian Pleniglacial. Datings suggest that conditions in the Late-glacial and Holocene were favourable to an organic-rich silt sedimentation which drowns the bottom of the valley in the context of a river running particularly slowly.
