“…Because of the large thickness of this unit, 14 samples were collected for luminescence dating (Tysz_8 -Tysz_21), and 28 luminescence ages were obtained. It is very characteristic that according to luminescence results, the loess cover in the L1L1 unit was created during a 3-5 ka period, which means that the calculated loess sedimentation rate for this unit is more than 3 mm per year which seem to be very high compared to about 1 mm per year calculated for different European loess profiles (Frechen et al, 2003;Antoine et al, 2009). For most samples, the results for the polymineral fraction agree within error limits with the results obtained using quartz.…”

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.

“…In Europe, the following periods of loess accumulation are correlated with OIS 3: 50-40 ka and 36-33 ka in Belgium, 65-35 ka in France, >40 ka and 40-25 ka in Germany, 55-40 ka in Czech Republic, 35-25 ka in Hungary (Frechen, 1999;Frechen et al, 1997Frechen et al, , 1999Frechen et al, , 2001Frechen et al, and 2003. Similar results (42-28 ka) were also obtained for samples from NW Ukraine (Nawrocki et al, 2003).…”

“…Loess material in Europe is considered to be of local origin so it was probably transported by surface winds from a short distance of up to several tens of kilometres (Dolecki and Łanczont, 1995;Maruszczak, 1986;Frechen et al, 1999;Chlebowski et al, 2003). Very extensive comparative studies on TL and IRSL methods applied to silt deposits from Hungary, Czech Republic, Germany, Belgium, and France (Frechen, 1992 andFrechen et al, 1997Frechen et al, , 1999Frechen et al, , 2001Frechen et al, and 2003 reveal that the total-bleach method applied to those silts, which are defined in literature as reworked loess, slope wash deposit, deluvial and solifluction loess, gives overestimated results, adequately to insufficient bleaching of TL signal. However, the results of IRSL and TL dating of typical/proper loesses are usually consistent with geologic interpretation so it is confirmed that the total-bleach method can be used for dating of Aeolian silt deposits.…”

Loesses cover a large area in SE Poland so their exploration is an important part of the palaeogeographical studies on Pleistocene. The research involves stratigraphic problems. At present, luminescence dating provides the greatest number of chronostratigraphic data concerning loesses. In this work we report TL ages of loesses from the last two glacial cycles in SE Poland, obtained in the TL Laboratory of the Department of Physical Geography and Palaeogeography, Maria CurieSkłodowska University in Lublin after 1993. Samples for TL dating were collected in 11 loess profiles (2-9 samples in each site) in order to obtain additional information for stratigraphic interpretations deduced from paleopedological, lithological, structural, and other data. Basing on the comparison of 54 TL ages, we can determine age intervals, in which the dating results of similar values assemble, and then get general information about the periods of intensified Aeolian accumulation related to defined stratigraphic units. The TL ages of all samples were obtained using the total-bleach method (TB) for the determination of the equivalent dose.

“…The best loess sequences, owing to their high sedimentation rate that can reach 0.5-2 m/ka during the 35-to 17-ka time interval (13,14), are indeed well-suited to study millennialtimescale environmental changes. High-resolution stratigraphy, paleopedology, grain size, magnetic properties, malacology, and organic and isotopic geochemistry can be used to reconstruct rapid variations of aeolian dynamics, relative temperatures, paleoprecipitation, and vegetation cover during the Last Glacial (15).…”

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
