The main aim of this paper is to understand the tectonic activity of the Central Slovak Fault System during Late Eocene to Miocene period. During this time the strike-slip faults influenced the structure of the Western Carpathians. Both regional fault patterns and their kinematics are a result of the regional stress field. The fault analysis along the Central Slovak Fault System enables to reconstruct the distribution of paleostresses. NE-SW (Late? Paleocene–Middle Miocene) as well as NW-SE distensions (Middle–Late Miocene) have been identified.
