Clay-mineral fingerprints from modern and fossil lake sediments from Lake Donggi Cona, situated on the north-eastern Tibetan Plateau were studied to determine changes in sediment provenance and environmental development since the late Glacial. To infer the source areas of the lake sediments, characteristic facies units (cover sediments and soils) from the catchment of the lake were studied concerning...
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...
Most studies on landscape evolution on the Tibetan Plateau during the late Quaternary have mainly focused on using lacustrine records. However, mantles of sandy silt and paleosols also provide valuable archives for reconstructing Holocene paleoenvironmental change. Yet little is known about the distribution and timing of these late Quaternary aeolian sediments. To enhance understanding and knowledge...
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...
Geomorphological and sedimentological investigations in the lower reaches of the Orkhon River in northern Mongolia provide evidence for Late Pleistocene terraces, Holocene soil development, aeolian accumulation, soil erosion and slope wash. Optically stimulated luminescence (OSL) and radiocarbon dating of aeolian and colluvial sediments including paleosols show different sedimentation and soil formation...
Mantles of silt- and sand-size particles, paleosols and fluvial deposits preserve valuable information on Holocene environmental change. These archives were used to reconstruct the landscape history in the upper Orkhon Valley close to the former capitals of the Uighurs (Kharbalgasin Tuur) and the Mongolian Empire (Karakorum) near the recent town of Kharkhorin, Central Mongolia. A holistic approach...
