An assessment of the relationship between the Darang fault and the Kazerun- Burazjan fault system and their fractures pattern

The Kazerun-Burazjan fault is an active strike slip fault with an N-S trending located in the Zagros belt whose performance causes bends and stretches in the folds axis. The obtained results from the seismic profiles of the southern parts of Fars province suggest that there is no evidence as to the continuation of Burazjan fault segment along the Mand Mountain to Persian Gulf as the end part of the Kazerun fault. Studies show that the performance of the faults such as the Mountain Front Fault (MFF) and the rotation of the blocks adjacent to the strike-slip faults caused the Burazjan fault to slip under the Khormuj and Khartang anticlines and the Bangestan Group located in the Khormuj and Siah anticlines to be placed beside the Aghajari formation in the Kaki anticline. The orientation of the long axis of the Khormuj and Namak (Jashak) salt domes with N-S trends can be considered as the activity of the segments of the Burazjan fault system. Surface and subsurface studies have introduced the Darang fault with an N-S trend and strike slip mechanism as the southern terminus of the Kazerun- Burazjan fault system which extends from the Khartng anticline to the Persian Gulf. The fractures result from the fault system performance consists of a series of transverse-shear fractures with NNE-SSW and NW-SE trends with a visible distribution around the folds axis.
