Main parallel structures of study area such as Chatroud, Pasib, Dehoo, Bondar faults and Cahroud syncline have NW-SE trend. Other two trends of structures are N-S (South Hikoh fault) and NE-SW (Kordehghan fault). Chatroud syncline is one of the main folds, that have E-W axial surface trace in SE part. Field investigations showed S-SW dipping Dehoo, Bondar, Pasib faults that have main component of reverse mechanism and have been cut by young NE dipping Chatroud reverse fault. Geometry and mechanism of these faults is comparable with Forethrusts and Backthrusts. Also, main structures based on field investigations and using satellite images have been introduced, then results have been compared with structures in experimental and analogue modeling of Sokoutis (2000) and Bonini (2003). In this model effect of lateral difference in adjacent crustal blocks has been favored.
