Abstract


A NEW APPROACH TO THE STRATIGRAPHY OF NEOPLEISTOCENE PALAEOLAKE AND GLACIAL DEPOSITS IN PIŁA

Abstract. A section of organic and mineral sediments at Piła was studied by means of geological, petrographical and palynological methods. The present paper presents a reconstruction of the development of vegetation during the Eemian Interglacial, as revealed by pollen analyses of lacustrine deposits in the Pił/2 section. It also discusses stratigraphic problems of the adjacent glacial deposits in the Piła area. The peat and organic silt sediments show a complete sequence of plant communities and climatic changes during the Eemian Interglacial. Six regional pollen assemblage zones (E 1 and E 3-E 7) have been distinguished. Litho-petrographical studies allowed us to recognise two glacial tills in the section considered. The Eemian Interglacial sediments are underlain by till representing the Wartanian Glaciation, and overlain by a Vistulian Glaciation till.
