Penultimate period of deglaciation in the Grudziądz Basin, Lower Vistula River Valley: An interstadial-like interval of the middle Wiirm
Geographia Polonica (1975) vol. 31, pp. 213-235
In the present paper an attempt has been made to reconstruct the processes of down-wasting of the penultimate ice sheet of the Last (Baltic, North Polish, Wiirm) Glaciation in the area of the Grudziądz Basin based on the analysis of the deposits and fossil landforms observed in three exposed profiles, including first radiocarbon dating. These profiles, selected from several ones which have been studied in the Lower Vistula Valley (E. Drozdowski, 1974), indicate quite well the type and succession of the deglaciation processes; in consequence they present a general picture of palaeogeographical conditions and make it possible to correlate them with definite evolutionary stages of the Last Glaciation observed in other areas.
