The thesis deals with lithological, stratigraphic past by geological environment the Silesian unit on the territory of the Moravian-Silesian Beskydy and Podbeskydská upland. Specifically, it is profile on stream of Ondřejnice near to Hukvaldy in the Czech Republic. It is ascertained by analyzing collected rocks by laboratory methods.
