The internal structure of Paleoalpine thrusts of the Western Carpathians: A case study from the Križná thrust system

Abstract

The aim of this article is to point out the complicated internal structure of Paleoalpine thrusts of the Western Carpathians and the consequential ambiguous interpretations of the tectonic transport of these tectonic units. The example used here is that of the internal structure of the Kriźná thrust system in the area of the Demänová and Il'anová Valleys in Nízke Tatry Mountains.The form that the Kriźná thrust takes is that of three individual thrust sheets. These overthrust each other along differently oriented thrust ramps. The geometry of the ramps influences the direction of the thrust displacement of the individual thrust sheets of the Kriźná thrust.
