The purpose of this study is lithostratigraphic investigation of Oligocene–Miocene salt deposits in the SE Persian Gulf. This study is based on lithostratigraphy and biostratigraphy data, gamma ray and sonic logs of nine drilled wells along southeast Persian Gulf to Strait of Hormuz. As a result, the Oligocene–Miocene deposits of this region were subdivided into four formations (Fms) which include Pabdeh Fm (Rupelian–Chattian), Asmari Fm (Rupelian–Aquitanian), Gachsaran Fm (Aquitanian) and Mishan Fm (Burdigalian). The salt and evaporated deposits situated between the Pabdeh and Gachsaran Fms which are assigned to the Aquitanian age. Finally the stratigraphical setting and distribution of the salt deposits are cleared.
