Abstract [en]

The Pomeranian ice margin is one of the most prominent ice-marginal features of the Weichselian glaciation innorthern Europe. Previous results of surface-exposure dating (SED) of this ice margin disagree with establishedchronologies and ice retreat patterns, i.e. are much younger than previously expected. We crosscheck the age of thePomeranian ice-marginal position in northeastern Germany using single-grain quartz Optically Stimulated Luminescence(OSL) dating of glaciofluvial sediments. OSL dating indicates an active ice margin between 20.11.6 kaand 19.42.4 ka forming outwash plains attributed to the Pomeranian ice-marginal position. On the basis of theseresults, we suggest a critical reassessment of previous SED data available for the Pomeranian ice-marginal positionwithin their respective regional geomorphological contexts. From a process-based point of view, SED ages derivedfrom glacigenic boulders document the stabilization of the landscape after melting of dead ice and landscapetransformation under periglacial conditions rather than the presence of an ice margin. SED indicates a firstphase of boulder stabilization at around 16.40.7 ka, followed by landscape stabilization within the area attributedto the recessional Gerswalder subphase around 15.20.5 ka. A final phase of accumulation of glaciolacustrine andglaciofluvial sediments at around 14.71.0 ka documents the melting of buried dead ice at that time.
