This Paper disscuses a determination and measurement of fault planes in Jihlava area in Moravian Moldanubicum and Strazek Moldanubicum. Over the 100 faults was measured during the field trips. The fault planes and striations was measured by the geological compass. The sence of movement was determined by kinematic indicators. Obtained data were processed by MARK 2006 software and they were plotted in the projection by Spheristat 2.2 software. Main normal stress directions were calculated by using orientation of fault planes and the sence of movement in MARK 2006 software. Four stress phases was determined.
