Abstract

The importance of glacial till occurrence in loess type sections of Poland and Ukraine.S u m m a r y. The presence of glacial tills in eight loess type sections documenting, in most cases, a complete rhythm of climatic changes during the last 780 ka (Brunhes epoch) in Poland and Ukraine, allows to precisely establish the age of these tills. The oldest till in Odonów, Kolonia Zadębce, and Bojanice represents the Sanian 2 (Elsterian 2, Okanian) Glaciation. The younger till (in Wąchock, Gradińsk, and Wjazowok) corresponds to the ice-sheet extent during the Krznanian (Saalian 2, Dnie per 1) Glaciation, and the youngest till (in Wąchock, Bugaiwka, and Stajki) to the ice-sheet extent during the Odranian (Saalian 3, Dnie per 2) Glaciation. The occurrence of these glacial tills in the discussed loess sections is crucial for the corrlation of glacial and extraglacial stratigraphic schemes for the Pleistocene of Europe.
