Contact between the Upper Cretaceous rocks of the Subsilesian Nappe and the overthrust Lower Cretaceous rocks of the Silesian Nappe is uniquely exposed at locality Ostravice River Chanell. The deposits of the Silesian Nappe in the zone of overthrust plane that belong to the Hradiste Formation are tectonically affected. The more exact age of the mentioned rocks has never been documented earlier. The most significant stratigraphic data were obtained by the analysis of calcareous nannofossils. The sediments of the Hradiste Formation in the zone of overthrust of the Silesian Nappe belong to two partial tectonic slices. Sediments of slice on the contact between both the Nappes is, according to calcareous nannoplankton, of latest Hauterivian to Early Barremian age. In the area of the rapids, the other slice lying on it is of Late Hauterivian age. Micritic limestones occurring in the Late Hauterivian slice indicate basinal sedimentation above the carbonate dissolution level.
