Abstract
The Hronská pahorkatina highland belongs to the particular morphostructures of the north-eastern part of Danube Basin with the typical pattern of fluvial valleys. Orientation and character of the fluvial valleys together with brittle disruptions of the Pliocene sediments has been object of the morphotectonic and structural analysis. Transversal asymmetry of the valleys and their arrangement refer to fault predisposition. The Pliocene sediments are affected by normal faulting with different orientation of the fault planes in NE–SW and NW–SE directions. Orientation of the faults corresponds to orientation of the fluvial valleys. The faults origin was connected with reorientation of the stress field during the Latest Pleistocene to the Holocene.
Key words: morphotectonics, brittle structures, neotectonics, Danube Basin, Western Carpathians
