Abstract
The Hormoz Formation of InfraCambrian age is the oldest unit recognized in southern Iran. It consists mainly of salt, other evaporites and débris of basement rocks. Some huge blocks of the uppermost PreCambrian and Lower Cambrian layered rocks were lifted to the surface by uprising Hormoz salt.A detailed field investigation within three major salt diapirs located in the SE segment of the Zagros Fold Belt was carried out. Some lithologic‐stratigraphic correlations between three formations within selected salt domes on the western part of the Zagros crush zone, and the equivalent units on the eastern part, are established.The Permian transgressive sea deposited basinal clastics unconformably on the Devonian in central Iran, and overstepped the basement rocks in central Arabia. The Pecten species of the Lower Jurassic Neyriz Formation of the Zagros Fold Belt can be correlated with the Nayband Formation of central Iran. The Tertiary evaporites of SSW Iran are correlated with the Tertiary evaporites of central Iran.Evidence discussed indicates the presence of a single tectonic entity with no geologic break between SW Iran and the plateau of Iran in the NE.
