Abstract [en]

Quaternary deposits in the overdeepened Wehntal, Switzerland, were investigated using both seismicprofiling and the analysis of 93.6 m long drill core using sedimentology, geochemistry, palynology,magnetic properties, and luminescence dating. The sediments reveal evidence for two glacial advancesthat reached the area during Marine Isotope Stage (MIS) 6. The first advance (w185 ka) may have carvedout the basin or at least removed the entire previous Quaternary sediment filling. This first advance likelyreached far beyond the limit of the maximum of the Last Glaciation. The second advance (w140 ka) wasof smaller extent, possibly of cold-based nature, and likely reached only slightly beyond the limits of theLast Glaciation.
