Late Quaternary landscape evolution in the Wadi Sabra (Jordan) based on sedimentological and geochemical investigations Spatial

This Ph.D.-thesis focuses on the Levant as a potential main corridor of human dispersal from Africa to Europe during the Upper Pleistocene. For the related palaeoenvironmental research in the Eastern Mediterranean region, significant and reliable climate proxies as well as Palaeolithic in-situ sites are scarce. Consequently, the investigation of environmental interactions and migration pathways of ancient human cultures requires advances in the prospection of archaeological sites and associated...

Technological and Typological Change at the Middle to Upper Palaeolithic Boundary in Lebanon Spatial

The dissertation is based on the study of lithics in order to explore cultural-historic connections across the Middle to Upper Palaeolithic boundary in Lebanon between 50-35,000 years ago on one hand, and between different regions in the Levant on the other. Besides the study of some 10 assemblages from Lebanon, additional data was acquired through published literature. For the first time, it could be testified that so called transitional industries in Lebanon are not connected to the preceding Middle...

Upper Paleolithic of Middle Dniester: Doroshivtsi III site Spatial

As a result of excavations of the Doroshivtsi III open-air site in the Middle Dniester region, seven Upper Paleolithic cultural levels were discovered in the 12 m thick loess profile. With the exception of level 1 with very few artifacts, all other cultural levels could be determined as Gravettian. The richest collections belong to level 3 and 6. Level 6 is dated to 22,330 ± 100 BP, and represents an original UP industry with shouldered points, a small amount of burins, and numerous backed tools made mainly...

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. ...
