The Fars and Hormuzgan Zones is eastern domain of the Zagros Belt which characterized by the outcrops and sub-crops of Precambrian-Cambrian Hormuz Salt. Deep-seated extensional faults played a major role in controlling the distribution and thickness variations of the Hormuz series and played important role in triggering and localizing the salt walls and diapirs This suggests that part of halokinesis could have been localized along the Precambrian-Cambrian extensional faults. Differential loading is the most probable principal mechanism for initiating and driving halokinesis in the Hormuz Salt Basin in Early Paleozoic. Therefore, it is expected that dissimilar types of the earlier salt related structures have their own influences on the geometry of present-day structures. Therefore, objective of this study is understanding role of the Hormuz Salt as basal décollement on long term sedimentation and relatively short term shortening happened by the Zagros Orogeny. Most of the folds in this study area are mainly folded on the Hormuz salt detachment with NW-SE trend and variable sizes. Almost all the asymmetric anticlines in the study area are SW verging.But there are some folds whit unconventional shape whit one or both narrow and linear plunges. We used sand box modelling technique for better understanding geometry of the hidden earlier structures which were masked by the Zagros Orogeny
