Kinematic Analysis of Fault Structures in Eghlid Area, Margin of High Zagros

The study area, located in the east of Eghlid town, between the northeast of the Abadeh Fault and southwest of the Zagros Main Fault, consists of the highly deformed rocks, which have been emerging clearly in tectonic crashed zone. Kinematic analysis carried out for determining the paleostress directions and deformation history of the area. Thus, the geometry of the fault plan/fault zone brittle structures and other kinematic indicators were measured based on the field observations and analysis carried out via data analysis inversion method and statistical models. The geological evidences provided necessary data for determining formation ages of the structures based on the relative time scale. According to the results, it can be concluded that three different faulting phases were efficacious in formation of the analyzed faults. During the faulting phases, three reverse fault systems developed respectively; imbricate fans thrust system, hinterland dipping duplex and inverted normal faults.
