Pradolina warszawsko-berlińska w rejonie Łęczycy: budowa geologiczna, rzeźba terenu i ewolucja
The Warsaw-Berlin ice-marginal spillway near Łęczyca; geology, landforms and their evolution

Summary/Abstract: The problem of the functioning of the Warsaw-Berlin ice-marginal spillway presented in the article results fromthe morphological features of the area and its watershed position. The analysis of the geological structure and identification ofthe lithology of the sediments filling the buried valley of the bottom of the ice-marginal spillway near Łęczyca were aimedat demonstrating their deposition during the Vistula Glaciation and connections with the activity of proglacial waters andthe conditions prevailing in the foreland of the ice sheet. The filling of this fossil form consists of the Vistulian mineral series,which is sandy-muddy, and covered by organic-mineral deposits of the Late Vistulian and Holocene.
