Abstract

Evolution and regional climate changes during the Late Glacial/Holocene transition were studied using organic and inorganic geochemical proxies and pollen data from Lake Khotavets (NW Russia). Palaeoclimatic and palaeosedimentation sequence was described for the time slices 13.5 – 12.9, 12.9 – 11.8 and 11.8 – 11.1 cal. ka BP, attributed to the Allerød, Younger Dryas and Preboreal, respectively. Rapid organic accumulation, decrease of minerogenic input and woods expansion ~11.8 cal. ka BP were associated with the Holocene warming. The presented reconstruction determines scientific justification for specific geodiversity conservation.
