Paleoenvironmental reconstructions on a (supra-)regional scale have gained attention in Quaternary sciences during the last decades. In terrestrial realms, loess deposits and especially intercalations of buried soils, so called loess-paleosol sequences (LPS) are important archives to unravel response e.g. climatic fluctuations reconstruct paleoenvironments Pleistocene. The analysis LPS requires knowledge several key factors, such as distribution aeolian sediments, their location relative...
Loess-paleosol sequences (LPSs) are important terrestrial archives of paleoenvironmental and paleoclimatic information. One the main obstacles for investigation interpretation these is uncertainty their age-depth relationship. In this study, four different dating techniques were applied to Late Pleistocene Holocene LPS Balta Alba Kurgan (Romania) in order achieve a robust chronology. Luminescence includes analysis grain-size fractions both quartz potassium feldspar best results obtained...
The source of aeolian sediments such as loess has been investigated since decades. Reliable knowledge on potential dust sources is crucial to understand past climatic and environmental conditions accompanying the dispersal early modern humans (EMH) into Europe. Provenance studies are usually performed small sample sets most established methods expensive time-consuming. Here, we present results high-resolution geochemical analyses five loess-palaeosol sequences from Lower Danube Basin (LDB),...
Abstract. The loess–palaeosol sequence and intercalated Palaeolithic find layers at the former brickyard of Rheindahlen are matters ongoing scientific dispute. age different palaeosols loess layers, hence their correlation with global climate cycles, timing repeated Neanderthal occupations have been hotly debated. These disagreements should be solved because exceptional sedimentary sequences provide a unique opportunity to study diachronic changes in behaviour within context past change. We...
Geo- and palaeoecological studies focusing on the late Pleistocene require a detailed knowledge of spatial distribution aeolian sediments. In Germany, existing maps are either large scales, have regional focus or show significant inaccuracies such as artificial boundaries within different geological units. To obtain more detailed, seamless map sediments their potential source areas, we combined reanalysed available geodata, using Geographical Information System. The resultant (scale: approx....
Abstract. Loess–palaeosol sequences (LPSs) of the oceanic-influenced European loess belt underwent frequent post-depositional processes induced by surface runoff or periglacial processes. The interpretation such atypical LPSs is not straightforward, and they cannot be easily used for regional to continental correlations. Within last few years, however, gained increased attention, as are valuable archives landscape dynamics. In this study, Siersdorf LPS was analysed using a multi-proxy...
Stable organic carbon and nitrogen isotopes can be used to interpret past vegetation patterns ecosystem qualities. Here we present these proxies for two loess‐palaeosol sequences from the southern Carpathian Basin reconstruct palaeoenvironment during 350 ka establish regional commonalities differences. Before now, isotopic studies on loess this region were only conducted deposits last glacial cycle. We methodological tests involving complete decalcification of samples prior stable isotope...
The Carpathian Basin is a key region for understanding modern human expansion into western Eurasia during the Late Pleistocene because of numerous early hominid fossil find spots. However, corresponding archeological record remains less understood due to paucity well dated, contextualized sites. To help rectify this, we excavated and sampled Crvenka-At (Serbia), one largest Upper Paleolithic sites in obtain radiometric ages artifacts evaluate their depositional context subsequent site...
Abstract. Archeological and geoscientific research in loess landscapes remains challenging due to erosional discordances the relocation of sediments by fluvial erosion slope wash. The Lower Rhine Embayment (LRE) can serve as a blueprint for archeological paleoenvironmental Central Europe. accumulation wind-blown dust; paleosols developed therein; artifacts preserved loess, colluvial or alluvial are evidence Pleistocene Holocene dynamics landscape. Geomorphologic processes different specific...
Loess-paleosol sequences are widely spread across central and southeastern Europe studied intensively, as they important terrestrial archives that preserve paleoenvironmental paleoclimatic information. In the Lower Danube Basin large areas covered by loess, loess derivates, sandy sand dunes (Lehmkuhl et al., 2021). The exposed deposits reach several decameters in thickness. contrast to other well-studied sites area, investigated Balta Alba Kurgan (BAK) sequence is located close forelands of...
<p>The vast Pleistocene aeolian sediments of the Lower Danube Basin are an important archive Quaternary palaeoclimate dynamics in Southeast Europe. The intercalation loess layers and fossil soils, so called loess-palaeosol sequences (LPS) interpreted as results oscillating climate phases past. However, characteristics these LPS vary quite strongly, since they influenced by various factors. Those factors mainly (palaeo-) climate, relief availability source material, which differ...
<p>Loess-paleosol sequences are in the focus of paleoenvironmental research because they offer potentially quasi-continuous terrestrial records environmental change. For on paleoenvironments, paleoclimates, and human evolution studies reliable dating approaches essential. Age models can be based different methods, e.g. proxy data correlation chronometric approaches. Urluia loess-paleosol sequence, which provides a high-resolution record covering Last Glacial Cycle Lower...
<p>Loess is an important archive of environmental change covering approximately 10% the Earth’s terrestrial surface. Numerous studies have analyzed loess deposits and in particular loess-paleosol sequences. To analyze these sequences, it to know spatial distribution aeolian sediments, their location relative potential source areas, geomorphology sink area. We investigated aspects by compiling a new map sediments Europe using highly resolved geodata from 27...
<p>The palaeoanthropological record of Western Romania is a prime archive the early modern human presence in Southeastern Europe. Regional stratified Upper Palaeolithic open-air and karstic sites enable us to infer temporal spatial patterns behaviour various geomorphological settings. However, are often prone reworking processes caused by local landscape instabilities. The pristine archaeological palaeoenvironmental stratigraphic evidence overprinted fluvial slope processes....
Modelling of the polarized cyclotron emission from magnetic cataclysmic variables (MCVs) has been a powerful technique for determining structure accretion zones on white dwarf. Until now, this achieved by constructing regions (for example arcs and spots) put in hand, order to recover emission. These models were all inferred indirectly arguments based polarization X-ray light curves. Potter, Hakala & Cropper (1998) presented (Stokes imaging) which objectively analytically region(s) MCVs....
