Osady biogeniczne pradoliny warszawsko-berlińskiej w rejonie Łęczycy i błonia (środkowa Polska) jako wskaźnik zmian środowiska
Biogenic sediments of the Warsaw-Berlin ice-marginal spillway in the area of Łęczyca and Błonie (Central Poland) as an indicator of environmental changes

Summary/Abstract: The belt of peatland covering the floor of the Warsaw–Berlin ice-marginal spillway in the area of Łęczyca is the larg-est wetland in central Poland. The deposit of biogenic sediments has a variable thickness. It is composed of lake sedimentslying on the floor in the form of isolated patches, and the main part consists of moss-herbaceous peats. The accumulation ofbiogenic sediments began in the Late Vistulian. Research work was undertaken to reconstruct the course of environmentalchanges in the Late Vistulian and Holocene, in relation to habitat changes, as well as to record the role of this landform forhuman activity in prehistory and the modern economy.
