Die hochwürmzeitlichen Rückzugsphasen des Rhein-Vorlandgletschers und der erste alpine Eisrandkomplex im Spätglazial

Abstract

The Upper Pleistocene Wurm Glaciation Recessional Stades of the Alpine foreland glaciers of the Rhine area, and the first Alpine boundary complex of the Late Pleistocene. In the Rhine area of the Wurm glaciation, the recessional Stades can be morphologically subdivided by means of glacial boundary complexes. The Würm-Stem-on-the-Rhine complex is evidence for an upper Wurm readvance of the foreland glaciers after an intensive melting period (± 16 000 y BP?). The first Late Pleistocene readvance of the local northern Alpine glaciers appears as the Würm-Weissbad complex (± 14 000 y BP?), while in the main network of the glaciation no reaction is recognizable. In the Upper Pleistocene of the Wurm, the equilibrium line of the Rhine glacier was at an elevation of 1000 m. The first readvance of local glaciers in the Late Pleistocene took place at an elevation of about 1500 m.
