oa Verification of structural relationships in the Kazerun-Borazjan Fault Zone

The Zagros Fold-Thrust Belt of southern Iran is a Neogene orogen that resulted from the collision between the Arabian Plate and Iranian terranes in the Eurasian Plate. In this mountain belt a set of N-trending faults that are, basement structures disrupt the NW-trending longitudinal Zagros folds. One of these faults, the Kazerun-Borazjan Fault Zone, stretches from the eastern termination of the Recent Zagros Main Suture, in the north, to the Iranian Coastline in the south. This zone is associated with anticlines and folds, and at the surface, it is delineated by two NS-trending linear structures that correspond to major dextral strike-slip faults. These faults are clearly evident on satellite images and seismic sections. In the vicinity of the Kazerun–Borazjan Fault Zone, joints that strike preferentially N-S are interpreted as shear-type features related to present-day tectonism. In addition, many minor strike-slip faults have affected the morphology of this area. One of the major effects caused by the strike-slip faults is the anti-clockwise rotation of Gisakan Block.
