Lake sediments ofthe northern Mologa-Sheksna Lowland were for the first time studied using high-resolution x-ray fluorescence scanning and AMS dating, supplemented with x-ray diffraction, total organic carbon, grain-size and magnetic susceptibility measurements. The combined results revealed sedimentation type changes during the Late Glacial and Early Holocene, which were associated with the proportions of allogenic and authigenic material in the deposits. Short-lived periods of low allogenic activity were registered ~14.0 cal. ka BP and~ 13.0 cal. ka BP, interrupted by episodes ofenhanced minerogenic input and low organic accumulation ~13.7, ~13.l and ~11.5 cal. ka BP. The outlined intervals correspond with the Late-Glacial climatostratigraphic units ofthe North Atlantic region. The beginning ofthe organic sedimentation~11.7 cal. ka BP indicates climatic warming of the Early Holocene. During the Younger Dryas and Early Holocene, until ~11.0 cal. ka BP, the sedimentation was furthermore influenced by the lake-level changes.
