Abstract

This study is intended to open the criticism of views so far held of the origin deformations of sedimentary bodies in glaciated areas. "True" tectonics just as glaciotectonics preferred in the recent past lose their justification for numerous deformations of Pleistocene successions of beds. In Pleistocene and older successions a sharp lithological change of sedimentary bodies in vertical succession, inversion of density and unequal loads of a plastic substratum widely or to deformations. Permafrost and mollisol initiate, or favour, the origin of gravitational deformations in loose sediments with a "high componental mobility". Like rock melts and salts, clays just as lignite and chalk are particularly suited to react plastically under imposed loadmakes it necessary to interpret again the majority of umsetted moraines, furthermore the eskers, oare kames, and kettle holes. The thus resulting bedding forms correspond to the style of deformation of germanotype in the Saxonian zone. The results of these investigations are of consequence to all problems connected with the exploration of raw materials in the Pleistocene glaciated area of North and Central Europe.
