Timing of the Late Vistulian (Weichselian) glacial phases in Poland

The Lower Vistula Region in northern Poland is a stratotype area for the Vistulian (Weichselian) glaciation and during Last Glacial Maximum (LGM) the southernmost extension of the Scandinavian ice sheet occurred in western Poland and in eastern Germany. Reinterpretation of the available geochronological data (radiocarbon, Cl-36 and Be-10 ages), supplied with new field geological evidence, mostly for the Late Vistulian ice sheet limits and movement directions, was focused in three key regions in Poland. During the late Middle Vistulian there was one or two ice sheet advances in the Lower Vistula region. The Late Vistulian maximum ice sheet limit in Poland was time-transgressive and occurred at 24-19 kyrs BP (generally, the younger to the east). Ice sheet limits during the Leszno Phase occurred at 24 cal/Be-10/Cl-36 kyrs, the Poznan Phase ice sheet limit was dated to 19 Be-10/Cl-36 kyrs and the Pomeranian Phase ice sheet limit about 16-17 Be-10/Cl-36 kyrs. Every Late Vistulian glacial phase in Poland was preceded by an ice sheet retreat. (c) 2010 Elsevier Ltd. All rights reserved.
