   This paper investigates the tectonic history and describes the paleostress evolution of the Hronov-Porici Fault Zone in the northeastern part of the Bohemian Massif A detailed structural research has been carried out in 50 localities. Faults and fractures have been investigated and measured. An analysis of the fault-slip data within the studied area resulted in the identification of four tectonic phases. The maximum principal stress was observed to be acting NE-SW during the first and youngest phase. The trend of the horizontal compression runs at 223 degrees in the horizontal plane perpendicular to the reverse faults occurring in this phase, as well as to the studied fault zone. The minimum principal stress was found to be subvertical dipping at 87 degrees and trending at 358 degrees. Both the brittle tectonic investigations and paleostress analysis have documented that, at present, the Hronov-Porici Fault Zone is under compressive regime with dextral component.
