The project is aimed at recognizing genesis of cover sand deposits on top of the sediments of ice-dammed basins that evolved in the foreland of the Scandinavian Ice Sheet (SIS) during different glacial episodes in its southeastern sector (from Poland to Estonia and Russia).The so called European sand belt stretches from the United Kingdom through the Netherlands, Belgium and Germany to Poland, from where it splits into northern (Baltic) and southern (Belarusian) belts. The aeolian, fluvial and lacustrine redistribution of fine-grained glacial sediments during the last deglaciation was strongly controlled by paleoclimatic parameters. Periglacial conditions with limited plant-cover favoured the activity of aeolian processes during and immediately after the glaciations. This makes the distribution and age of the coversand deposits of interest with respect to research into paleoclimate and climatic fluctuations. Therefore, it is assumed that the cover sand deposits’ lithology reflects their genesis which in turn allows reconstructing environmental conditions (wind activity, soil moisture, periglacial phenomena, availability of fine-grained sediments, loess formation). Dating of coversands enables reconstructing periods of drying up ice-dammed lakes, duration of periglacial conditions, possible re-activation of drift sands, and in wider context – verifying “upper time-limit” of existing age-models of the last deglaciation, and decay of large glaciolacustrine basins. Aeolian cover sands are particularly suitable for OSL/TL dating, and as such their age is potentially very valuable for additional verification of deglaciation chronologies. Outcomes of the project have primarily of scientific importance, but may well lead to practice-oriented conclusions (aeolian reactivation of sand massifs due to global climate trends, development of surface-water networks).
