The paper presents the results of integrated studies of Quaternary deposits in the western part of Taymyr Peninsula, Russia. Composition, structure, salinity and cryogenic features, including ice-wedges and massive ground ice, are described. New data on spore and pollen and fauna analyses are presented. The Sanchugov clay has proved to have marine genesis. The Kazantsevo deposits must have formed in near-shore environment and are represented mainly by clayey sediments. The Karga (Karginsky) deposits occur only locally in the studied area. The Quaternary sequence of Western Taymyr is capped by specific ice complex deposits.
