Isotopic-geochemical pilot investigations were carried out on a limnic sediment sequence from the former Lake Aschersleben in central Germany. Radiocarbon data based on peat and lake marl material cover a time span between approximately 2,560 BP and 17,030 years BP for the drilling cores investigated. The variations in isotope levels characterize the specific lake development such as changes in the temperature regime and the water balance from stable cold climatic conditions in the Upper Glacial period to warmer Late Glacial conditions partly influenced by the influx of glacial water and the rising water level in the Early Holocene.
The organic sediments at the Cheremoshnik site (the centre of the East European Plain) have been reinvestigated by pollen and macrofossil analysis in order to gather more detailed information on vegetation dynamics during the Late Pleistocene Glacial/Interglacial transition (boundary between OIS 6 and OIS 5e). Two phases of vegetation can be determined: an earlier forest substage ("warm") and a later ("cold") substage, when the forest communities were reduced in their area. There are probably some similar features between the succession of vegetation at the end of Dnieper (Saale) cold epoch and during the Valdai (Weichselian) Late Glacial (Alleröd and Younger Dryas).
