We are pleased to inform about another scientific publication of Dr hab. Paweł Zieliński, prof. UMCS (Department of Geomorphology and Palaeogeography, UMCS), published in Quaternary International:

Moska P., Sokołowski R.J., Jary Z., Zieliński P., Raczyk J., Szymak A., Krawczyk M., Skurzyński J., Poręba G., Łopuch M., Tudyka K., 2021. Stratigraphy of the Late Glacial and Holocene aeolian series in different sedimentary zones related to the Last Glacial Maximum in Poland. Quaternary International, doi.org/10.1016/j.quaint.2021.04.004.

Lateglacial and Holocene sandy aeolian sequences with palaeosol horizons located in different sedimentary zones in western-central Poland were analysed in order to establish their regional stratigraphical and palaeoenvironmental significance. Results of sedimentological, geomorphological and absolute dating methods from 3 representative profiles from an extraglacial zone (Leszczyca site), a glaciomarginal zone (Barczygłów site) and a glaciated zone (Godzięba site) are presented. A compilation of 31 luminescence dates from aeolian sands and 7 14C-dates from palaeosols formed the basement for establishing the stratigraphic position of the analysed deposits. The obtained results were correlated with reference to Greenland ice-core chronology, which has the best resolution for the Northern Hemisphere. In the extraglacial zone, aeolian deposition started in the Oldest Dryas and continued throughout the Older Dryas (main phase of dune built) with limited deposition in the Younger Dryas and finished in Preboreal. Aeolian deposition was interrupted by pedogenic processes in the Bølling and Allerød interstadials as well as in the Younger Dryas-Preboreal transition. Whereas in the glaciomarginal zone aeolian deposition started in the Younger Dryas and continued to the Early Boreal with a weakly expressed pedogenic process in the Early Preboreal. In the glaciated zone, aeolian deposition took place in the Younger Dryas. At the Barczygłów and Godzięba sites palaeosols of the Roman Period and 19th century were detected, covered by aeolian sands. The Subatlantic aeolian episodes were induced by human activity and registered forest fires. Identified periods of aeolian activity and pedogenic processes were correlated with other profiles from central and western Europe.

This publication was prepared within the NCN grant (2018/30/E/ST10/00616) entitled. "Multiscale studies and advanced methods for determining the numerical time scale in reconstructing the evolution of inland dunes in Poland during the end of the last glaciation" directed by Dr hab. Piotr Moska(Silesian University of Technology in Gliwice). MORE ABOUT THE PROJECT
