Die Umgestaltung des glazigenen Reliefs der norddeutschen Altmoränengebiete am Beispiel des Uelzener Beckens

Abstract. The study deals with the influence of the Weichselian periglacial shaping on the modification of older moraine areas; the basin of Uelzen, which is part of the North German lowland, has been taken as an example. It was by the inland-ice of the Warthe-period that this area was fundamentally formed, and during the Weichselian period it was subject to periglacial processes.

Two examples of a small-scale relief inversion caused by fluvial and soliflual processes are demonstrated. A calculation of the dimension of denudation in the basin itself, which has taken place 1.) since the retreat of the Warthe-glaciers and 2.) since the Eem interglacial stage, is possible; it is based 1.) upon the inversion of the drainage after the shrinkage of the ice and 2.) on the altitude of Eem interglacial sediments above the present basin bottom. According to these data an average degradation of the basin bottom of about 20 metres since the late Warthe period must be assumed; about 10 metres of this account are due to the Weichselian denudation exclusively.
