Palaeogene flysch deposits of the Oravska Lesna area, portion of the proximal zone of the Magura accretionary wedge formed in front of the West Carpathians, indicates the NW-SE shortening as the oldest tectonic event. This shortening of the Palaeocene–Late Badenian age, is responsible for the most dominant currently present structures of this area including: NE-SW striking folds and thrust planes, steep to overturned bedding planes of the same strike, slump bodies, and W-E and N-S striking strike-slip faults which accommodated inhomogeneous thrusting as lateral ramps. Younger tectonic event, N-S shortening of the Late Badenian age, reactivated pre-existing fault plane pattern, including the continuation of the roughly N-S striking Zazriva sigmoide-large strike-slip fault zone which started to act as the dextral strike-slip fault for the first time. Pre-existing NE-SW striking dip-slip reverse faults were reactivated as oblique-slip reverse faults. The youngest, the Late Badenian–Late Sarmatian tectonic event, controlled by the stress field with the NE-SW oriented maximum principal stress axis, reactivated original reverse fault pattern as strike- and/or oblique-slip faults. This faulting accommodated the NE-ward lateral motion of the rock mass which occurs in outcrops of the Oravska Lesna area.
