OSL data of the Balta Alba Kurgan loess-paleosol sequence, Romania SFB806 doi Spatial Temporal

This is the DRAC file (cf. Durcan et al., 2015) used for age calculation of the optically stimulated luminescence (OSL) dating data from the Balta Alba Kurgan loess-paleosol sequence in Romania. This dataset corresponds to the luminescence age data published in Scheidt et al. (2020). The sample names in the first column are encoded as follows: Profile-number_sample-number_protocol. So for example sample BAK1_1_IR50 gives the results of conventional IRSL at 50°C measurements for sample no. 1 in profile BAK1....

Spatial loess distribution in the eastern Carpathian Basin: a novel approach based on geoscientific maps and data doi

Geo- and palaeoecological studies in the Carpathian Basin require a detailed knowledge of the distribution of aeolian sediments. Existing maps are not detailed enough and erroneous as a result of the basic input data and scale used. Here we present a map showing the detailed distribution of loess sediments in the Carpathian Basin at the border of Hungary and Romania using a Geographic Information System and the vectorized, statistically analysed geological map of Hungary (scale 1:300,000) and the Romanian...

Long thin blade production and Late Gravettian hunter-gatherer mobility in Eastern Central Europe doi

The regular and systematic production of long blades (>120 mm) that maintain a thickness (<10 mm) of regular blades (<120 mm) is a particular phenomenon of the Upper Palaeolithic (40–10 ka BP) archaeological record of Eastern Central Europe. However, the mechanical underpinnings of manufacturing these long blades are still not fully understood. This paper presents experimental research that used heavy (∼800 g) and light (∼570 g) antler percussors to test the effect of percussor weight on the manufacture of...

Tracing the Influence of Mediterranean Climate on Southeast Europe during the past 350,000 years doi

Loess-palaeosol sequences are valuable archives of past environmental changes. Although regional palaeoclimatic trends and conditions in Southeastern Europe have been inferred from loess sequences, large scale forcing mechanisms responsible for their formation have yet to be determined. Southeastern Europe is a climatically sensitive region, existing under the strong influence of both Mediterranean and continental climates. Establishment of the spatial and temporal evolution and interaction of these...

Three climatic cycles recorded in a loess-paleosol sequence at Semlac (Romania) – implications for dust accumulation in south-eastern Europe doi Spatial

Recent investigations of the Semlac loess section in the south-eastern Carpathian Basin, which is situated at an undercut slope position on the right bank of the Mureş River in its lower reaches (Banat region, western Romanian), are presented and discussed. Dating back to marine isotope stage (MIS) 10, the more than 10 m thick loess sequence includes four fossil soil-complexes developed in homogenous and relatively fine silty loess. Because of the good preservation of the sediment, Semlac is regarded as a...

Digital image analysis of outcropping sediments: Comparison to photospectrometric data from Quaternary loess deposits at Şanoviţa (Romania) and Achenheim (France) doi

The possibility to use colour data, as extracted from two selected loess-paleosol sequences, is discussed here. Colour data are a fast and inexpensive method of proxy data generation. We compare the outcome from analysing outcrop images taken by digital cameras in the field and spectral colour data as determined under controlled laboratory conditions. By nature, differences can be expected due to variations in illumination, moisture, and sample preparation. Outcrop inclination may be an issue for...

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) doi

Loess sequences provide important and at least a partial continuous record of Quaternary palaeoenvironmental change; some of the sequences even bury archaeological remains. In addition, loess-palaeosol sequences provide valuable information concerning environmental change and climate evolution. In this study, we compare two sections: (1) The Middle to Late Pleistocene loesspaleosol section of Semlac in western Romania (MIS 10 – 1), and (2) the sandy-loess section of Doroshivtsy in western Ukraine (MIS...

Testing feldspar against quartz luminescence dating of the sandy loess sediments from the Doroshivtsy site (Ukraine) doi

Post-infrared infrared stimulated luminescence (pIRIR) dating has reactivated the use of feldspar minerals to date Pleistocene deposits. We compared pIRIR stimulation measured at 290 °C (pIRIR290) of coarse grain feldspar (100–200 μm) and optically stimulated luminescence (OSL) of coarse grain quartz (100–150 μm) with radiocarbon dating. The samples were taken from the lower part of the Doroshivtsy sandy loess sequence, which contains Gravettian artefact layers. The site is one of the very few sections in...

A resistivity-depth model of the central Azraq basin area, Jordan: 2D forward and inverse modeling of time domain electromagnetic data

The focus of this thesis is the geophysical exploration of the central part of the Azraq basin in the northeastern desert of Jordan. In addition to common 1D inversion techniques, further 2D forward modeling strategies and a rarely used 2D inverse modeling scheme are applied to transient electromagnetic data. The Azraq area is of potential interest for palaeoclimatical and archaeological research in the frame of the interdisciplinary Collaborative Research Centre 806, entitled "Our Way to Europe" (CRC 806)....

Investigation of the Azraq sedimentary basin, Jordan using integrated geoelectrical and electromagnetic techniques doi

The Eastern Mediterranean has been used as a passageway for human migration from Africa to the Middle East, the Balkans and Europe. The Azraq basin in the eastern desert of Jordan has been a major spot for human settlements since the middle Pleistocene. The former lake in the basin centre has developed to a hyper-saline alluvial mudflat, the Qa’ Al Azraq. In the mudflat thick sequences of alluvial sediments are deposited. Such sediment successions are promising archives used for reconstructing a...

Environmental dynamics and luminescence chronology from the Orlovat loess-paleosol sequence (Vojvodina, northern Serbia) doi Spatial

The Carpathian Basin contains some of the best preserved loess deposits in Europe, including some of the continent's longest and best resolved climate records. Large areas of the basin have been intensively investigated in recent years, although deposits in the east remain largely unstudied, despite considerable regional variation in climate records. Here we discuss the sedimentary record exposed in the Orlovat brickyard using detailed litho- and pedo-stratigraphic, enviromagnetic parameters and...
