Geology of the Magura Nappe, south-western Gorce Mountains (Outer Carpathians, Poland)

Abstract

The studied area, located in the south-western part of the Gorce Mountains, is built of flysch deposits representing the Krynica and Bystrica Subunits of the Magura Nappe. Here, in the Late Cretaceous–Early Miocene part of the lithostratigraphic succession of the Krynica Subunit, four formations containing several members were distinguished, whereas in the Bystrica Subunit, only one Middle Eocene–Oligocene formation was identified. The Turbacz and Kudłoń Thrust Sheets in the tectonic structure of the Krynica Subunit and the southernmost fragment of the Tobołów Thrust Sheet in the Bystrica Subunit are prominent. Several folds occur in the studied area. Numerous transverse and oblique faults are also present. The result of the present geological investigations in the study area was the creation of a geological map of the Magura Nappe deposits in the Gorce Mountains. In general, a high-resolution digital elevation model contributed significantly to the progress of this geological research.
