| Zusammenfassung |
| Upper Pleistocene geoarchives in the Pannonian Basin are predominantly composed of loess-paleosol sequences accompanied by only few fluvial archives dating to this time frame. In 2015 a 10 m sediment core was recovered within an extensive loess area by means of vibracoring, with the recovered sedimentary succession mainly composed of limnic sediments. Coring was conducted within a depression northwest of Vrsac and east of the Banat Sands in the eastern Carpathian Basin (North-Eastern Serbia) in a region still lacking in paleoenvironmental records but which must have played a crucial role in the spread of modern human into Europe along the main rivers valley tributary to the Danube. Radiocarbon dating places the upper half of the core within the last ca. 20 ka, whereas luminescence dating is on going. Sedimentological analyses give evidence of phases of eolian sediment input within a predominantly limnic depositional environment. Aeolian sediment input has been altered, and early diagenesis is expected to have superimposed the eolian sediment. In addition, levels of carbonate precipitation can be observed in the core, some intervals being very rich in clay and decalcified; both show strong alteration of original sediment. No indications for fluvial input are apparent, suggesting a continuous sedimentation during the Upper Pleistocene and into the Holocene.
Here preliminary results are presented including core images and description, XRF scans, grain-size data and an age model in progress. Based on these findings a detailed interpretation on the sedimentary system and (paleo)environmental processes involved are given. |
