Description
Summary:The cross-instrumental dating of the Quaternary deposits in the Sambia (Kaliningrad) Peninsula has made it possible to obtain a time series that indicates the formation of a sequence overlapping the Last Glaciation deposits in the Late Holocene under subaerial conditions with active aeolian accumulation starting from 450–400 BP. The earlier established fluvioglacial genesis and Late Glacial age of the surface deposits need to be revised. Greater aeolian activity is presumably related to climate changes during the Little Ice Age. OSL dating of very young (Late Holocene) subaerial deposits demonstrates the reliable results supported by agreement with the radiocarbon analysis data and the stratigraphic position of the dated sequences.
