Geological characterisation of the Krynica Subunit in the vicinity of Krościenko on the Dunajec river (Magura Nappe, Outer Flysch Carpathians)

The aim of this work is to the present geological structure of the Krynica Subunit of the Magura Nappe in southern part of the Gorce and Beskid S1decki Mountains and along the Pieniny Klippen Belt (PKB). Formal lithostratigraphic units were distinguished on the basis of mapping. The lithostratigraphic units are the age of Middle Paleocene – Middle Eocene age. Flysch deposits were classified as the Szczawnica Formation with the yczanow Member, Zarzecze Formation and Piwniczna Member of the Magura Formation in the investigated area. Strike-slip faults and faulted formations complicate the geological structure of the described region. The creation some of these faults is connected with andesite intrusions. Strong faulted strata occurs in the southern part of the region along the overthrust of the Pieniny Klippen Belt on the Magura Nappe. The contact line between the Pieniny Klippen Belt and Paleogene of the Magura Nappe is heterogeneous. The evidences of it are outcrops of klippen, which occur within the Szczawnica Formation and the Zarzecze Formation.
