Some Aspects of Glacial Erosion and Deposition in North Germany

Abstract

In the marginal areas of the Pleistocene Scandinavian ice sheet in north Germany there are few signs of direct glacial erosion. Fine gravel analyses show that glacial reworking was not very important. This may be partly due to the fact that at least in the late phases of the glaciation the active parts of the ice sheet moved over dead ice and were not in direct contact with the underlying substratum. Buried tunnel valleys with a depth of more than 400m show that considerable erosion by sub glacial melt-water streams took place, at least during the Elsterian glaciation.
