The Aurignacian way of life: Contextualizing early modern human adaptation in the Carpathian Basin doi Temporal

The culture and dispersal of early modern humans are top priorities of many research agendas. While the debate primarily centers on genetics, dispersal trajectories and points of earliest presence, the context (climate, landscape, demography, culture) of the colonizing process is usually considered in a coarse-grained manner or even ignored. To understand the context of human dispersal and to decipher relevant push and pull factors requires the consideration of multiple environmental proxies and the...

Millenial scale climate oscillations recorded in the Lower Danube loess over the last glacial period doi

In this study we provide a correlative age model for last glacial loess at the Rasova-Valea cu Pietre site in the Lower Danube region, based on the correlation of palaeoenvironmental proxies to independently dated palaeoclimate archives, luminescence dating and independent age control provided by the geochemically confirmed presence of the Campanian Ignimbrite (CI) tephra. The CI tephra, originating in the Phlegrean fields of southern Italy, has been dated elsewhere by 40Ar/39Ar to 39–40 ka BP, and is...

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...

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...

Danube loess stratigraphy — Towards a pan-European loess stratigraphic model. doi

The Danube River drainage basin is the second largest river catchment in Europe and contains a significant and extensive region of thick loess deposits that preserve a record of a wide variety of recent and past environments. Indeed, the Danube River and tributaries may themselves be responsible for the transportation of large volumes of silt that ultimately drive loess formation in the middle and lower reaches of this large catchment. However, this vast loess province lacks a unified stratigraphic scheme....

Influence of HCl pretreatment and organo-mineral complexes on laser diffraction measurement of loess-paleosol-sequences doi

The influence of different sample pretreatment methods on grain size distributions in particle size analysis has been subject to controversial discussions. Standard sample preparation typically comprises the disaggregation of aggregated and agglomerated particles into single primary particles, i.e., the organic binding material is oxidized by hydrogen peroxide (H2O2) and the contained carbonates are dissolved by hydrochloric acid (HCl). The aim of this study is to evaluate the effects of HCl treatment on...

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...

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...
