“…On the other hand, we think that very low dose rate for the oldest sample and the obtained equivalent dose of about 185 Gy for the oldest samples should not be underestimated. The ages obtained in this study, are also simi- lar to those obtained from equivalent units in Dolni Vestonice (Czech Republic, Antoine et al, 2013), Korshiv (Ukraine; Fedorowicz et al, 2013) and Saxony (Germany, Meszner et al, 2013).…”

Abstract:The presented work concerns a loess profile located in Tyszowce, in the eastern part of Poland on the Volyn Upland, close to the Ukrainian border. The investigated loess formation is well preserved and is characterised by clear stratigraphic units providing an opportunity to refine the loess chronostratigraphy in Poland. In the paper, we present luminescence ages of loess from the last glacial cycle in SE Poland (up to about 100 ka) together with seven radiocarbon ages. Twenty-one samples were collected and dated using infrared (post-IR IRSL) and blue light stimulated luminescence dating. Two fractions were used, namely polymineral fine grains (4-11 µm) and medium sized quartz grains (45-63 µm). The obtained luminescence ages show very good agreement of both methods in relation to loess deposits, however for the fossil soil units the post-IR IRSL method yields older ages. Radiocarbon dates also confirm luminescence chronostratigraphy for younger units. Moreover, the luminescence results are supported by detailed analyses of grain size distribution, carbonate content and magnetic susceptibility variations allowing to create a comprehensive picture of chronological evolution of this site.

“…This result is also about 20% higher than for quartz grains and OSL method (Moska et al, 2015). The obtained results are similar to those obtained for this region, Biały Kościół (Moska et al, 2012) and Dolni Vestonice in the Czech Republic ; also Fedorowicz et al (2013) report similar results for Korshiv (Ukraine) loess profile and Meszner et al (2013) for Saxony in Germany. Alluvial loam which is located just below the S1 unit was deposited probably during MIS6, during the final phase of penultimate glaciations.…”

Luminescence chronostratigraphy for the loess deposits in Złota, Poland

Loess formations in Poland display a close relationship with cooling and warming trends of the Northern Hemisphere during the Pleistocene. Loess sequences sensitively record regional palaeoclimatic and palaeoecological changes. The Złota loess profile (21°39'E, 50°39'N) provides a unique opportunity to reconstruct climate conditions in the past in this part of Poland. This continuous sequence of loess and palaeosol deposits allows to distinguish between warmer and more humid climate which is favourable for soil development and much colder and dry periods which are conducive to loess accumulation. The silty and sandy aeolian material originates mainly from weathered rock surfaces affected by frost shattering or from glaciofluvial/fluvial deposits of river flood plains. In Poland, loess and loess-like formations occur in the southern part of the country, mostly in the south polish uplands, i.e. in the Lublin, Sandomierz, and Cracow Uplands. We used different techniques to establish a chronological framework for this site. 21 samples for luminescence dating were collected from the investigated loess profile in Złota. Infrared post-IR IRSL dating method was applied to the polymineral fine grains (4-11µm). The dating results are accompanied by detailed analyses of the geochemical composition, organic carbon and carbonate. Also, analysis of magnetic susceptibility and grain-size distribution were investigated. Based on such a large stratigraphic dataset an age-depth model using OxCal has also been constructed for this site.

“…This configuration induced a widening of deflation areas on the continental shelves of the North Sea and Channel and in large river valleys and a very strong increase in detrital particles available for Aeolian deflation and transport, enabling the deposition of markedly thicker loess units over Europe (35). A second marker level, observed around 23 ka at the top of tundra gley G7, is characterized by a sharp decrease in the GSI, an almost complete disappearance of the rich mollusk fauna of Nussloch (17), a shift from finely laminated to homogeneous loess in Western and Central Europe (26,27,30), and a significant increase in the sand content in Eastern Europe (28,29). This marker level at ∼23 ka, also recorded across the European Loess Belt, indicates a shift to markedly more arid conditions between 23 and 20 ka contemporaneous with maxima in ice sheet extension and volume.…”

The characterization of Last Glacial millennial-timescale warming phases, known as interstadials or Dansgaard-Oeschger events, requires precise chronologies for the study of paleoclimate records. On the European continent, such chronologies are only available for several Last Glacial pollen and rare speleothem archives principally located in the Mediterranean domain. Farther north, in continental lowlands, numerous high-resolution records of loess and paleosols sequences show a consistent environmental response to stadial-interstadial cycles. However, the limited precision and accuracy of luminescence dating methods commonly used in loess deposits preclude exact correlations of paleosol horizons with Greenland interstadials. To overcome this problem, a radiocarbon dating protocol has been developed to date earthworm calcite granules from the reference loess sequence of Nussloch (Germany). Its application yields a consistent radiocarbon chronology of all soil horizons formed between 47 and 20 ka and unambiguously shows the correlation of every Greenland interstadial identified in isotope records with specific soil horizons. Furthermore, eight additional minor soil horizons dated between 27.5 and 21 ka only correlate with minor decreases in Greenland dust records. This dating strategy reveals the high sensitivity of loess paleoenvironments to Northern Hemisphere climate changes. A connection between loess sedimentation rate, Fennoscandian ice sheet dynamics, and sea level changes is proposed. The chronological improvements enabled by the radiocarbon "earthworm clock" thus strongly enhance our understanding of loess records to a better perception of the impact of Last Glacial climate changes on European paleoenvironments
