Paleostress analysis in Bozqush Mountains، northwest Iran

Knowledge of the local stress field in a region is important in the structural and affecting factors on structural kinematics studies. Therefore¡ in this paper after describing the basic theoretical principles of stress inversion method from slickensides¡ it was used field measured heterogeneous fault –slips as raw data to determine the average state of the principal stress axes in order to analyze the regional geodynamic situation of this area. The results of the reduced stress tensor from fault-slip measured data¡ show 21/156¡ 64/012 and 14/251 states for σ1¡ σ2 and σ3 axes respectively. The results of analysis of these data show substantial agreement between the determined principal stress axes and recent tectonic research in this region.
