Summary:
The structure of the Carpathians geosystem contains information on the litho-facial, sedimentological, geodynamic, tectonic, paleogeographic history of the region development and those processes that took place during the Meso-Cenozoic. The main factors in the formation of shift-hazardous zones are related to the processes of geological reorganization in Early and Late Cretaceous, on the boundary of the Cretaceous and Paleogene, in Paleocene, Eocene, Oligocene and Neogene. Olisthostromes, mudflows, and landslides widely developed at the different stratigraphic levels. Considering diversity of the processes that led to the formation of the modern landscape, including shift-hazardous zones, a comprehensive systemic analysis was carried out. The stratigraphy serves as a basis for detection of landslide hazardous zones. Analysis of the events and processes is a key for determining the event-stratigraphic criteria of geological evolution.
