Abstract
OUTLINE OF GEOLOGICAL EVOLUTION OF THE PIENINY KLIPPEN BELT, CARPATHIANS
Summary
The Pieniny Klippen Belt represents trace of a major axial suture in the Carpathian fold belt, about 600 km long but only from a few hundred meters to about 20 km wide. it is a heterogenous structure consisting of the Klippen successions proper and their sedimentary cover, of inner Carpathian (Manin etc.) and Outer Carpathian (Magura) units incorporated in the Belt during its long deformational history.
Nine distinctive stages of structural evolution of the Pieniny Klippen Belt have been distinguished: (A) Initial stage of basin formation as a result of extensional faulting close to the Triassic - Jurassic boundary; (B) Initial expansion stage due to oceanic-type rifting and ocean- floor spreading (Triassic - Jurassic boundary and Early Jurassic); (C) Pelagic stage (Jurassic- Early Cretaceous); (D) Initial compression stage (Early Cretaceous) related to partial subduction of the Pieniny Klippen Belt Basin under southern Exotic Cordillera (Andrusov Cordillera); (E) Main Late Cretaceous - Early Tertiary compression stage, including three successive deformation phases related to subduction in the central and northern furrows of oceanic basement under the Exotic Cordillera (southern = Andrusov Cordillera) and the Czorsztyn Ridge (northern), respectively; (F) Palaeogene expansion stage; (G) Early Miocene (Savian) compression stage - the result of collision between the European Plate and the Central Carpathian-Pannonian Microplate; (H) Early Miocene (late Savian) transpression stage due to rotation of Inner Carpathians respective to Outer Carpathians along the Pieniny Klippen Belt, with the formation of longitudinal strike-slip faults; (J) Mid-Miocene (Styrian) compression stage expressed in the Pieniny Klippen Belt as transversal strike-slip faults.
