Tektonika północno-zachodniej części fliszu podhalańskiego

Leonard Mastella, Wojciech Ozimkowski, Ryszard Szczęsny



In the northwestern part of the Podhale flysch area, along the contact zone with the Pieniny Klippen Belt, there is a zone with tectonic deformations resulting from uplifting of this klippen belt. This contact is a dislocation of reverse fault type in the west and of normal one in the east of the analysed area (Figs. 1, 2). It is cut by numerous faults, some of which with azimuths of 15-40° are the Riedel shears R' (Fig. 1). They indicate sinistral displacements along the contact of the Podhale flysch and the klippen belt. In the eastern part of the analysed area and to the south of the peri-contact deformation zone, there is the peri-Pieniny flexure (Figs. 1, 3). Its origin is to be referred to the probable reverse fault in the substrate •with a southern downthrow. Probably structures of the klippen belt extent in the flysch substrate as far as this fault line.
Large fault zones with azimuths of NNE - SSW cut the Podhale flysch and the klippen belt (Fig. 1). They are mainly normal or vertical faults with poorly indicated sinistral component. The eastern side was thrown down along the largest fault zone (Biały Dunajec zone) what resulted in considerable lowering of the klippen belt structures in the eastern part of the analysed area.
