ABSTRACT

Glaciotectonic features can be found in most of the areas that have been affected by Pleistocene continental glaciations. Glaciotectonic features result from the complex energy system determined primarily by behaviour of the ice mass together with the form and geological characteristics of the substratum. Southwestern Poland is very complex from a geological point of view. The pre-Alpine Sudete mountain range was formed during the Caledonian and the Variscan periods (although some older, Precambrian elements are also known). The abundant glaciotectonic features in southwestern Poland show both differences and similarities in horizontal and vertical extent of the deformations, in their tectonic style and direction, in deformation intensity and character of the strain, in complexity of the structural systems, in their relationship to the buried bedrock relief and the locally-dominant lithology and in age. Analysis of the distribution of glaciotectonic features in southwest Poland shows a succession of changes in the deformational environments from the north to the south.
