Depositional history of the North Taymyr ice‐marginal zone, Siberia—a landsystem approach
Abstract The sediment–landform associations of the northern Taymyr Peninsula in Arctic Siberia tell a tale of ice sheets advancing from the Kara Sea shelf and inundating the peninsula, probably three times during the Weichselian. In each case the ice sheet had a margin frozen to its bed and an inter...
