The study area is including of Zagros orogeny belt and Persian Gulf that both of them have been formed on northeastern part of Arabian plate. There are 84 emergent salt diapirs that origi- nated from Hormuz formation with Infra-Cambrian to Cambrian age. Based on location, shape and orientation of the emergent salt domes in the east Zagros hinterland and Persian Gulf foreland ba- sin, internal motivation forces in the salt deposits has been predominant compared to later tec- tonic forces. In the other words, most of the emergent salt diapirs are pre-orogenic diapirs and they had got prominent role as pines in determining the shape and location of next structures during to the Zagros orogeny. Finally, Neogene continental collision has a supplementary role to diapirism and salt reactivation. However there are an evidence to syn-orogenic emergent diapirs that they have got an important role in the progressive deformation. Keywords Emergent, Diapirs, Tectonics, Zagros, Iran 1. Introduction Investigation of emergent salt diapirs in the east Zagros region in Iran (Figure 1), is the main purpose of this re- search. Dominant structural trend in the study area is E-W. From tectonics point of view, it contains the overth- rusted and simple folded belts of Zagros that formed on the northeastern part of Arabian plate’s passive margin [1]-[3]. Zagros Mountains have been continued to East Taurus Mountains in Turkey and have named Za- gros-East Taurus hinterland. Zagros-East Taurus hinterland is an external platform (fold and thrust belt) in north * Corresponding author.
