2009 m. Nr. 3-4 Sedimentary succession in Berezno in the Volhynia Polesie (Ukraine) as an example of depositional environment changes in the periglacial zone at the turn of the Vistulian and the Holocene
This paper reports the results of investigations in the eastern part of the European sand belt. The lithological variability of alluvia as well as overlying aeolian sands and silts was determined in the Berezno site (Western Ukraine) located on the right-bank, higher terrace of the Slutcha River. Based on the described deposit succession, using the results of lithofacial, granulometric, morphoscopic, and TL analyses, the primary deposition environments were reconstructed. Periglacial structures were also characterized and interpreted. The dependence of the deposition conditions and rate on the transformation of Plenivistulian and Late Vistulian severe climate was shown. An attempt was also made to define the influence of local factors on fluvial, fluvio-aeolian, and aeolian deposition. Alimentation areas for aeolian deposits and dominant wind directions were also indicated. Keywords: periglacial zone, fluvio-aeolian and aeolian deposition Berezno site |
