Faghan fault system, constrain on the late Cenozoic kinematics of the Northern Lut Block, Central Iran

The E-W trending Faghan fault system with >180 km in length located in the northern part of the Lut Block and south of the Dorouneh Fault in central Iran. The fault cut through basement rocks and all other younger units from Cambrian to Cenozoic. Kinematic and dynamic analyses of the Faghan fault system is crucial for understanding the tectonic framework of the northern part of the Lut Block. These field based investigation analyses of the Faghan fault system indicates the E-W trending dextral strike- slip shear kinematics for the fault system and as Principal Deformation Zone (PDZ) along which minor sinistral, dextral and dip slip faults have also formed as second order riedel shears. Therefore, like the Kuh-e-Sarhangi fault zone, the Faghan fault system is considered as one of the fundamental fault zone in the north of the Lut Block caused the deformation partitioning in the block during Late Cenozoic. Accordingly, the Faghan fault system  divorces  the Bardacan-Kashmar and Gonabad micro-blocks from each other and transfers the deformation from the main Lut Block into its northern micro-blocks by Intraplate escaping tectonics.
