Lateglacial to Holocene pedogenesis and formation of colluvial deposits in a loess landscape of Central Europe (Wetterau, Germany) Spatial

Loess areas in Central Europe have been settled since ancient times and are therefore predestined to archive information about both the paleoenvironment with and without human activities. In gentle rolling loess-landscapes distinct short and shallow valleys, so-called dells, are prominent landscape elements that act as sediment traps. The loess-paleosol-colluvium (LPC) sequence of Gambach (Wetterau, Germany) can be regarded as an exceptional sequence for Lateglacial-Holocene pedogenesis and human impact in...

Palaeoclimate Reconstruction in the Levant and on the Balkans Spatial Temporal

For an understanding of the climate system’s variability, knowledge of the past climate is essential. Continuous observations are not available for longer than the last 100 years, a period that is insufficient to understand the variability and sensitivity of the climate system. Since information of both is necessary to build good climate models, the reconstruction of the past climate is fundamental. With palaeoclimate reconstructions it is possible to get information about the past climate and the climate...

LumReader R package

A series of functions to estimate the detection windows of a luminescence reader based on the filters and the photomultiplier (PMT) selected. These functions also allow to simulate a luminescence experiment based on the thermoluminesce (TL) or the optically stimulated luminescence (OSL) properties of a material.

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...

Neolithic transition and lithic technology: The Epipalaeolithic and Early Neolithic assemblages of Ifri Oudadane, NE-Morocco Temporal

Ifri Oudadane represents one of the few recently excavated sites in NW-Africa which permits a study of the Neolithic transition. The site is dated by 23 radiocarbon ages suggesting an occupation between 11.0 and 5.7 ka calBP. The well-documented Neolithic transition occurred at about 7.6 ka calBP. This transition is marked by the appearance of pottery, cereals and legumes. Furthermore, geochemistry and micromorphology indicate several changes in the sedimentation milieu. One of the most interesting...

Megabiome changes over the last 120kyr (HadCM3) SFB806 doi Spatial Temporal PaleoMaps

This geospatial dataset contains climate data from 120 ka to 0 ka in 1000 to 4000 year steps as raster data. The variable shows biomes representing nine different climate conditions modeled with the HadCM3 - general circulation model. The source data from Hoogakker et al. (2016) was imported from the original published NetCDF file and translated to multiple GEOTIFFs with GDAL. The raster data has been converted to single GeoTIFFs with GDAL’s gdal translate and gdalwarp tool. The dataset has a resolution of...

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 Temporal

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 Temporal

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...
