LUMINESCENCE DATING OF LOESS DEPOSITS FROM THE REMAGEN-SCHWALBENBERG SITE, WESTERN GERMANY doi

This study describes the luminescence characteristics of quartz of Upper Pleistocene loess of the Middle Rhine area. The loess/palaeosol sequence of the Schwalbenberg near Remagen comprises a multitude of interstadial soils and soil sediments that have been dedicated to the Marine Isotope Stage 3 (MIS 3). These weak calcaric cambisols and their derivates are underlain by loess and soil sediments of MIS 4 to MIS 5 and covered by loess sediments and intercalated gelic gleysols of MIS 2. We applied...

Optical dating of sediments in Wadi Sabra (SW Jordan) doi

At Wadi Sabra (SW Jordan) human occupation dates back to the Palaeolithic and Epipalaeolithic. Although there is stratigraphic correlation based on archaeological finds of Ahmarian origin, numerical age estimates are lacking. We applied single-aliquot optical dating of coarse grained quartz of wadi deposits and investigated the luminescence properties in detail to achieve more accurate age information about the time of human occupation. Weak luminescence signals and scattered dose distributions characterise...

Environmental change indicated by a site-specific grain size ratio - the example of the Semlac loess-paleosol sequence (Romania)

Loess sequences provide important and at least a partial continuous record of Quaternary palaeoenvironmental change. In addition, loess-palaeosol sequences provide valuable information concerning environmental change and climate evolution. It is customary to reconstruct such changes by means of grain sizes ratios. In this study, we calculated an site-specific grain size (GS) ratio (Schulte et al. in review) and compare this ratio with the common U-ratio (Vandenberghe et al.1985) and, in addition, with...

Climatological and environmental change as derived from physical and geochemical loess sediment properties: Examples of last glacial loess sites from the Pannonian Basin doi

The Project B1 within the CRC 806 “Our way to Europe” is focused on the "Eastern Trajectory" of modern human migration from Africa into Europe. The Middle East, Anatolia, Balkans and Southeastern Europe constitute the principal areas to be investigated. Within these larger regions key areas were selected for combined archaeological and geoarchaeological research, fieldwork having delivered case studies for initial Modern Human adaptational systems, yet to be fully...

Environmental Conditions on the corridor of human migration between 40,000 and 14,000 a BP in Balkan region. A multi-proxy approach on loess-paleosol profiles doi

This contribution focuses on two PhD projects, which are integrated within the collaborative research centre 806 “Our way to Europe” at the University of Cologne and the RWTH Aachen University (Germany). The main research focus is the migration of anatomical modern human (AMH) to Europe. We concentrate on the paleoenvironmental conditions on the route through southeastern Europe. This links the region with the earliest fossils of Homo sapiens sapiens (so far known) in the Middle East, Anatolia, the...

Multiple environmental change at the time of the Modern Human passage through the Middle East – First results from geoarchaeological investigations on Upper Pleistocene sediments in the Wadi Sabra (Jordan) doi Temporal

Upper Pleistocene sediments at Wadi Sabra (Ma’an District, Jordan) were geoarcheologically investigated from 2008–2010. The Wadi Sabra valley system, situated east of the Dead Sea Rift and south of the ancient Nabataean capital of Petra, has preserved sedimentary deposits which are connected with several Upper Paleolithic sites. First results from sedimentological and geochemical analysis supported by archeological and radiometric dating provide evidence of fluvial and fluvio-eolian sedimentation during...

Culture Change and Continuity in the Eastern Mediterranean during Rapid Climate Change: Assessing the Vulnerability of Neolithic Communities to a Little Ice Age in the Seventh Millennium calBC

In the past several years there has been increasing interest in a short interval of abrupt climate change known to have occurred towards the end of the 7th millennium calBC, most often referred to as the 8.2 ka calBP event. Growing numbers of studies have discussed the role of this interval in coincident Neolithic culture change in the region of the Eastern Mediterranean, albeit lacking a true comprehension of 1) the superordinate climate mechanism, and 2) further-reaching implications, e.g. the early...

Reconstructing fire regimes from geochemical proxies in Late Quaternary soils Spatial

Changes in ecosystems and land use frequently went along with regional burning events, but how fires accompanied human development, the onset of agriculture and changes in climate has eluded researchers. I hypothesised that information on past burning events may be reconstructed from the geochemical analyses of black carbon (BC), the residue of incomplete combustion. To test this hypothesis, it was the aim of my theses i) to elucidate the quantitative and qualitative characteristics of BC produced by...

Late Neanderthals at Jarama VI (Central Iberia)? doi

Previous geochronological and archaeological studies on the rock shelter Jarama VI suggested a late survival of Neanderthals in central Iberia and the presence of lithic assemblages of Early Upper Paleolithic affinity. New data on granulometry, mineralogical composition, geochemical fingerprints and micromorphology of the sequence corroborate the previous notion that the archaeological units JVI.2.1 to JVI.2.3 are slackwater deposits of superfloods, which did not experience significant post-depositional...

Genesis of loess-like sediments and soils at the foothills of the Banat Mountains, Romania - Examples from the Paleolithic sites Romanesti and Cosava doi Spatial

The Paleolithic sites Romanesti and Cosava, situated at the foothills of the Banat Mountains in Romania, provide an important testament of life of the first European modern humans (Homo sapiens sapiens) during the Middle Pleniglacial. Even though these sites have been extensively excavated, little is known about the site formation of related loess-like sediments and soils. First luminescence data at the two investigated sections confirm sediments from the penultimate glacial period to the Holocene. ...

Tephrostratigraphic studies on a sediment core from Lake Prespa in the Balkans doi Spatial

A detailed tephrostratigraphic record, which dates back to Marine Isotope Stage (MIS) 5b (ca. 91 kyr), has been established from a 17.76 m long core (Co1215) from Lake Prespa (Macedonia, Albania and Greece). A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11) were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the...
