Is there a need for readjustments concerning Late Pleistocene paleoenvironmental dynamics in the northern loess distribution zone of Bavaria (Germany)?

Abstract

Loess-paleosol-sequences (LPS) represent some of the most complete records of local-scale paleoenvironmental dynamics in terrestrial environments. The Attenfeld sequence is located around 4 km north of the Danube River and within the southern extent of the Franconian Jura in Bavaria (Germany). The Danube is believed to be one of the main sediment sources of LPS in Southern Germany and further east. However, studies on LPS in this area lack actuality. Therefore, a multi-proxy approach has been applied (analyses of grain-size distribution, element composition, and sediment color attributes). Additionally, two samples were taken for dating with optically stimulated luminescence (OSL). Results show that all preserved units experienced reworking, which might be due to generally higher precipitation amounts and a larger slope angle when compared to other LPS. Unexpected luminescence age estimates are raising further questions...
