Abstract

The results of geomorphological mapping of the vicinities of Konin have been verified by sedimentological, stratigraphical, radiometric and geochemical studies. The age of the maximum advance of the Vistulian ice sheet has been estimated as about 20 000 yr BP. The 14 C and TL dating is considered not only in terms of palaeogeography but also as a methodological approach. Geo-chemical analyses of tills differing in age, which occur in the vicinity of Konin, serve as a tool, by means of which the deposits can be described and allow an attempt to be made to use the resulting data for the purpose of relative dating of deposits accumulated directly by the ice sheet.
