Cechy teksturalne osadów jako źródło informacji o warunkach środowiska sedymentacji, na przykładzie osadów plejstoceńskich z profilu Glinojeck (Równina Raciąska)

Abstract

Texture features of Pleistocene deposits as a source of information on sedimentary environment conditions; a case study of Glinojeck borehole (Raciąż Plain).Summary. Analysis of the texture of sediments from the Glinojeck borehole (sheet Sochocin) allowed to better understand conditions of their accumulation environment. Sandy sediments were divided into fluvioglacial, fluvioperiglacial and fluvial units. Rate and duration of the accumulation processes were determined. The analysis also allowed to distinguish between thick units of glacial till. No sediments representing climatic optimum of any interglacial were found in the borehole since the sediments must have been accumulated in harsh environmental conditions (sparse vegetation and intensive aeolian processes during the Małopolanian and Great Interglacials).
