Shapes and timing of structures in Hormuz salt in the Zagros basin

     More than ۲۰۰ salt plugs are known in the ZFTB and its foreland but when and why they began to rise and their times of subsequent episodes of growth are not clear. Isopach maps of the Zagros cover sediments were used to extend forward the times that salt structures grew. We also consider the current shapes of the ۱۶۰ emergent structures now known to develop an evolutionary model for structures of Hormuz salt. Then, ۴۹ possible additions to the ۶۶ already known blind structures were suggested on the basis of structural contours drawn of the top Jurassic. The results demonstrate a clear relationship between episodic activity of the salt and the reactivation of olds faults in the basement both before and after the ZFTB began propagating to the SW and S in Eocene times.
