Deep-seated gravitational slope deformations in the highest parts of the Czech Flysch Carpathians: evolutionary model based on kinematic analysis, electrical imaging and trenching

Popis výsledku v původním jazyce

Deep-seated gravitational slope deformations (DSGSDs) played an important role during the evolution of mountain ridges of the Outer Western Carpathians. Four DSGSD-affected ridges in the highest part of the Czech sector of the OWC have been subjected tomultidisciplinary investigation. All the studied DSGSDs are strongly predisposed by regional structural fabric. The area of a single DSGSD can be affected by various types of slope movements. Electrical imaging and trenching revealed that besides these mechanisms, anisotropic flysch massifs formed by thick-bedded sandstones are strongly exposed to subsurface opening of air-filled voids related to widened crevices. Such a process is driven by deep-seated creep and translational sliding of sandstone bedsupon plastic claystones whose strength has been reduced to residual values. Performed dating revealed that some of the studied DSGSDs originated in the Holocene period, particularly in the Atlantic and Subboreal chronozones.
