Lössverbreitung im Pannonischen Becken - Problematik grenzüberschreitender Geodaten und Lösungsansätze mit GIS für eine Beispielregion (Grenzregion Ungarn-Rumänien) Spatial

To create a map showing the distribution of loess sediments in the Pannonian Basin in the border region of Hungary and Romania several different cross-border spatial data had to be used. Particularly there were problems because of the thematically content of the underlying international geodata, but also because of geodetical basics like projections and lingual barriers, respectively. To solve these identified problems some solutions were made e.g. by using the EU-INSPIRE-directive. However, the most...

Impacts of climate and humans on the vegetation in northwestern Turkey: palynological insights from Lake Iznik since the Last Glacial doi Spatial

The Marmara region in northwestern Turkey provides a unique opportunity for studying the vegetation history in response to climate changes and anthropogenic impacts because of its location between different climate and vegetation zones and its long settlement history. Geochemical and mineralogical investigations of the largest lake in the region, Lake Iznik, already registered climate-related changes of the lake level and the lake mixing. However, a palynological investigation encompassing the Late...

Paleoenvironmental reconstruction of loess-paleosol sequences in Serbia and Hungary - first luminescence data Spatial

Paleoenvironmental conditions in southeastern Europe may be important for modern human migration investigated within the CRC 806 “Our way to Europe”. Results of a multi-proxy approach on loess-paleosol sequences is presented.

Danube loess – paleoenvironmental record and potential eastern European corridor for the dispersal of modern humans Spatial

An international and interdisciplinary team is working on different proxy data for the paleoenvironmental reconstruction of the last glacial cycle as recorded by loess and similar terrestrial deposits. Our group focuses on loess sections, archaeological open air sites and cave sediments. The major topic is the environmental background of migration pathways of Anatomically Modern Humans (AMH) from Africa into Europe. We focus on Early Upper Palaeolithic sites in selected morphological positions....

Sedimentological dynamics of the Orlovat loess-paleosol sequence (Northern Serbia) show both local and regional paleoenvironmental fluctuations Spatial

The last glacial cycle as recorded in the Orlovat loess section (Northern Serbia) gives insight into both local and regional paleoenvironmental conditions. The Orlovat section is a unique section in the Carpathian Basin and it is characterized by irregularities in sedimentology, magnetic susceptibility, geochemistry and other paleoproxies. Therefore the local conditions need to be understood before making claims on a regional scale. Especially the grain size distribution indicates that the Orlovat site was...

Paleoenvironmental change as derived from loess sediment properties: Examples of last glacial loess sites from the Carpathian Basin Spatial

The project B1 within the CRC 806 “Our way to Europe” focuses on the "Eastern Trajectory" of modern human migration from Africa into Europe. The Middle East, and SE Europe constitute the principal areas to be investigated. SE Europe has become a special research focus since two early Homo sapiens individuals have been found at Oase Cave in the southern Banat. The fossils lack any stratigraphic context; cultural and environmental circumstances of these findings have remained unclear. In the...

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...

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...

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...

Quaternary climate change and Heinrich events in the southern Balkans: Lake Prespa diatom palaeolimnology from the last interglacial to present doi Spatial

Lake Prespa, in the Balkans, contains an important palaeo-archive in a key location for understanding Quaternary climate variability in the transition between Mediterranean and central European climate zones. Previous palaeoenvironmental research on sediment cores indicates that the lake is highly sensitive to climate change and that diatoms are likely to be strong palaeohydrological proxies. Here, we present new results from diatom analysis of a ca. 91 ka sequence, core Co1215, which spans the time from...

Paleolimnology of Lake Iznik (NW Turkey) during the past ~ 31 ka cal BP Spatial

Lake Iznik, situated in the Marmara region (NW Turkey), is an alkaline lake with about 300 km2 surface area, inserted in an area of typical Mediterranean climate. During the dry summer season, carbonates are precipitating from the water column. The endogen carbonate accumulation, e.g. aragonite, is expected to hold past climate information. A detailed understanding of the limnological system is required to differentiate site specific signals and responses to climatic forcing. Geochemical and mineralogical...
