Abstract
The Strike-slip faults are not linear and straight features visible on the map view and nature, as they become bent in their path. Bending causes compressional or tensional stress becomes predominant in the region. Astaneh and Firuzkuh faults are the two active strike-slip faults with ENE-WSW trend. Between these two active left-lateral faults, an imbricate fault zone with thrust component occurs. Furthermore, this zone cuts and offsets an anticline. The region is uplifted in this regime and forms a compressional horst between Chashm and Bashm faults; moreover, an additional horst is forming in the south east of the zone.
