Abstract: Morphostructure pattern suggests rotation of the Orava block along the Orava transforming transversal fault. The shortening of the Western Carpathians during their shift to the north in a N–S direction is well known, but the press in between the Bohemian Massif and the European Platform also caused substantial shortening in a W–E direction. The crucial role for such tectonic processes was played by the transversal Orava Fault and Orava block rotation. Paleomagnetic preliminary results and geophysical data seem to confirm such a hypothesis.
