The Orlovat loess-paleosol section - link between lowland loess plateaus and upland hills slope loess sediments in the Pannonian Basin

Carpathian (Pannonian) Basin presents an important part of dispersal of the anatomically modern human (Homo Sapiens Sapiens sp.) corridor from Africa to Central Europe. This area currently lies at the border between Atlantic, Continental and Mediterranean climate zones and therefore is potentially extraordinarily sensitive to past and present climate change. During Quaternary, huge amount of loess deposits have been accumulated over Carpathian Basin. In frame of the CRC 806 “Our Way to Europe” project, we...

Löß-Stratigraphie: Möglichkeiten, Probleme und Perspektiven


Environmental change indicated by grain-size variations and trace elements: examples from two different sections - the sandy-loess sediments from the Doroshivtsy site (Ukraine) and the loess section Semlac (Romania)


Middle to upper pleniglacial transition recorded in the loess profile of Krems-Wachtberg East Spatial

Loess research in Lower Austria has a long tradition and came back into focus of Quaternary research with new methodological approaches. Detailed paleoenvironmental information of the middle to upper pleniglacial transition is recorded in the Upper Paleolithic sites of Willendorf, Stratzing, Stillfried B, Grub and Krems-Wachtberg. The latter attracted international interest because of its unique infant burials. In the collaboration with archeologists, loess researchers profit from the integration of...

Investigating physical and chemical properties of last Glacial loess in the central Balkan region

The central Balkan region and the Carpathian/Pannonian Basin presents an important area for the dispersal of the anatomically modern human (Homo Sapiens Sapiens sp.) corridor from Africa to Central Europe. Last glacial loess and loess like deposits cover large parts of this region. In spite of widespread distribution of loess and loess-like deposits in the central Balkan and Carpathian Basin, information about the anatomically modern human occupation of these landscapes are rare. However, information about...

Analysis of Migration Processes due to Environmental Conditions between 40,000 and 14,000 a BP in the Eastern Mediterranean and Balkan region, Luminescence Dating

Integrated within the collaborative research centre 806 “Our way to Europe” this presentation focuses on the “eastern trajectory” of modern human migration to Europe. This route links the region with the earliest fossils of Homo sapiens sapiens (so far known) in the Middle East, Anatolia, the Balkans and the Northwestern Black Sea. The research emphasis of this project lies on the exact timing of the environmental conditions. To gain an understanding of past environmental conditions and variations, a...

Sedimentologische und geochemische Analysen des Sandlössprofils Doroshivtsi (West Urkaine)

The concerning sandy loess sequence, that extends to 9 meters, is situated on a slip-off slope of the Dnie-ster near Doroshivtsi in the south-west of the Ukraine. Since 2007, the section is investigated archaeolog-ically. This section is situated on the second terrace in the slope deposits. It is a remarkable sequence of seven consecutive achaeological layers, that are dated to the upper paleolithic. The area of the middle course of the Dniester was one of the most inhabited territories during the...

Environmental change indicated by grain-size variations and trace elements: An example from the sandy-loess sediments from the Doroshivtsy site (Ukraine) Spatial

The recently discovered loess section of Doroshivtsy became famous due to archeological findings of the Gravettian. The profile represents a about 9 m sequence of sandy loess, intercalated by more humic horizons. It is situated in a flat gully and at an undercut slope of the Dniester River close to the village Doroshivtsy in the south-western Ukraine. Radiocarbon dating and luminescence ages are conclusive within the expected age range of the Gravettian period (22-28 ka). The loess section is composed...

Geoarchäologische Untersuchungen in Ságvár (Ungarn) Spatial

Im Rahmen des SFB806 ‘Our way to Europe’ wurden im Herbst 2013 nahe der jungpaläolithischen archäologischen Stätte ‚Ságvár‘ (Ungarn) zwei Löss-Sequenzen beprobt. Die Profile befinden sich auf einer Hügekette südöstlich des Balaton in ca. 228 m Höhe an einem Hohlweg. Das erste Profil befindet sich auf einer Hügelkuppe, das zweite ca. 30 m hangabwärts. An den Sedimentproben wurden Korngrößenanalysen mittels Laserbeugung und geochemische Analysen mittels RFA Spektroskopie durchgeführt. Die...

Influence of HCl pretreatment on laser diffraction measurements

Sample pretreatment methods in grain size (GS) analyses differ and their influence on GS distributions has been subject of controversial discussions. The standard sample preparation usually comprises the disaggregation into single primary particles. The organic binding material is oxidized by hydrogen peroxide (H2O2) and the containing carbonates are dissolved by hydrochloric acid (HCl). However, laser diffraction measurements of calcified sediment sequences or sediments with high contents of organic matter...

Loess and loess-like sediments from the foothills of the Banat Mountains, Romania – Examples from loess sections and Paleolithic sites

New investigations from loess and loess-like sediments in the Western Plain of Romania provide evidences for a deeper insight and connection between long loess sections of the lowlands (Semlac) and short sections from the Carpathian foothills (Romanesti and Cosava). While the long loess sections provide evidence concerning climatic and environmental change since the middle Pleistocene the short sequences from the foothills include Paleolithic sites give information especially for the interstadial of the...

Aeolian dynamics at the Orlovat loess-paleosol sequence, northern Serbia, based on detailed textural and geochemical evidence doi Spatial

Previous investigations showed that the Orlovat loess–paleosol section, northern Serbia, is characterized by irregularities in sedimentological properties, magnetic susceptibility and color of the sediment. Here, we applied granulometric analysis and X-ray fluorescence (XRF) analyses to study how the sedimentation at the Orlovat site was conditioned by specific geomorphological or climatic conditions. Grain-size analysis is an established method and one of the most frequently used paleoenvironmental proxies...
