CHRONOLOGY OF THE VISTULIAN (WEICHSELIAN) GLACIAL EVENTS IN THE LOWER VISTULA REGION, MIDDLE-NORTH POLAND

Abstract: Stratigraphy of the Vistulian glacial events in the southern part of the Lower Vistula region in the north Poland is presented. Lithostratigraphic units and TL dating of Vistulian deposits exposing along the Vistula valley between Toruæ and the Che‡mno Lakeland are described in detail. The obtained results indicate that the Vistulian sequences in the Lower Vistula region were deposited during five palaeogeographical episodes. Three glacial events were distinguished: the first at the beginning of the Middle Vistulian (~6570 ka) and two younger ones during the Late Vistulian. The Middle and Late Vistulian glacial events were separated by a long ice-free period, between 65 and 30 ka. Key words
