ABSTRACT: The emergent salt diapirs
of the east Zagros, Iran have been investigated by their structural positions.
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 originated 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 basin, internal
motivation forces in the salt deposits has been predominant compared to later
tectonic 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.
