Západné Karpaty (pohorie) Pieniny Klippen Belt Form. Descr. články - journal articles Language English Country Germany Annotation The Pieniny Klippen Belt (PKB) and adjoining zones form a narrow, but lengthy belt that separates the Cretaceous nappe stack of the Central (Austroalpine) and the Cenozoic accretionary wedge of the External Western Carpathians (Flysch Belt). The PKB shares units and structures of both, in addition to the distinctive Oravic units, derived from a continental fragment in the Middle Penninic position. In map view, the northward-convex PKB consists of two branches—the western one striking roughly SW–NE and the eastern one oriented in the NW–SE direction. The western branch experienced a continuous NW–SE convergence and forward accretion of units derived from the foreland plate during the Late Cretaceous up to Oligocene. The developing accretionary wedge was supported by the backstop of the Central Carpathians. In contrast, the eastern branch originated by separation of PKB units and their dextral translation along the NE margin of the Central Carpathian block in the Late Eocene. During the Miocene reorganization of plate movements in the Carpathian area, the situation reversed. The eastern, formerly dextral transform margin was converted to the frontal backstop of the eastern part of the accretionary wedge. In contrast, the western, previously orthogonally convergent branch was affected by along-strike sinistral movements. Despite these considerable kinematic changes, the PKB remained fixed to both backstop edges and records deformation structures and associated sediments differentiated into several evolutionary stages.
