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 Basin, Jordan using Integrated Geoelectrical Techniques: 2D Modeling of Transient Electromagnetic Data

The Eastern Mediterranean has been the 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 center has developed to a 10 km × 10 km large hyper-saline alluvial mudflat, the Qa’ Al Azraq. In the basin center thick sequences of alluvial sediments, consisting mostly of clay and various evaporates, are deposited. We utilized the...

Geophysical field data recorded in Azraq, Jordan in 2011/2012

The central loop transient electromagnetic data were recorded in the central Azraq basin area, Jordan in two field surveys in 2011 and 2012. Two transects 5 km and 7 km long transects were investigated from the peripherie of the Azraq mudflat across its center. In total 150 soundings were recorded using either a 100x100 m transmitter loop for deep investigations down to approx. 120 m depth, or a 50x50 transmitter loop for fast transmitter turn-off times and shallow investigation. The data is processed, i.e....

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...

A geochemical approach on reconstructing Upper Pleistocene environmental conditions from wadi deposits - an example from the Wadi Sabra (Jordan) doi Spatial

Stratified Upper Pleistocene sediment sequences have been geochemically investigated in the arid environment of the Wadi Sabra (Southern Jordan). The wadi fills are associated to archaeological finds of Upper Palaeolithic to Epipalaeolithic age and intended for a reconstruction of palaeoenvironmental conditions during and after the time of the initial human occupation. As the mineralogical and sedimentological composition of the sediments is highly influenced by the nature of the local source rock, the...

Mapping the distribution of weathered Pleistocene wadi deposits in Southern Jordan using ASTER, SPOT-5 data and laboratory spectroscopic analysis doi Spatial

In the arid regions of the Levant, ancient wadi fills act as a terrestrial sedimentary archive with a high potential for preserving archaeological findings. This current study combines remote sensing with laboratory VIS-spectroscopy to investigate the spatial distribution of alluvial wadi fills in a small catchment in Southern Jordan. Due to its homogeneous sandstone geology, the composition of the alluvial sediments is highly influenced by the local bedrock whilst fluvial relocation and surface weathering...

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. ...

The Late Pleistocene Belotinac section (southern Serbia) at the southern limit of the European loess belt: Environmental and climate reconstruction using grain size and stable C and N isotopes doi Spatial

The Belontinac loess section is one of the southernmost loess-paleosol environmental archives for the Late Quaternary in Serbia. The climate at this site is intermediate between the continental and the Mediterranean realms, which makes this loess archive potentially highly sensitive to past climatic changes. This paper presents new insights into the paleoenvironmental history during the last glacial period in southern Serbia using grain size and isotope proxy data. The grain size parameters from the...

Jabrud II 4 DataSet LithicAnalysis SFB806 doi

This dataset comprises the techno-typological analysis of the lithic artefact assemblage of Yabroud rock-shelter II – Layer 4. This assemblage is part of a much larger collection of lithic artefacts and bone tools excavated at different localities in Yabroud by Alfred Rust between 1930 and 1933. The Yabroud collection is housed at the Institute of Prehistoric Archaeology of Cologne University, Germany.

Looking around Peştera Cu Oase: The beginnings of Upper Paleolithic in Romania Spatial

In contrast to the widely acknowledged anthropological finds in Oase Cave and to the key geographical position of Romanian territory for the assumed dispersion of Anatomically Modern Humans in Europe, the archaeological information regarding the emergence of the Upper Paleolithic in Romania remains poorly known to a broader scientific community. The prolonged theoretical and methodological isolation of the Romanian Paleolithic research has particularly contributed to keeping the regional archaeology out...
