Abstract: The aim of this study is to describe tectono-depositional structures resultant of Cretaceous, Tertiary and Miocene tectonic activities in offshore area of Strait of Hormuz (Eastern part of Persian Gulf) using various seismic interpretation and palinspastic restoration techniques. High quality 3D-seismic data from the offshore area of Strait of Hormuz display complex structural imaging of that found at the Northeastern margin of Arabian plate. Seismic profiles show presence of two main unconformity surfaces; the lowermost is at the base of upper Cretaceous that is called Turonian Unconformity or top Bangestan group and the upper one is at base of Miocene and is named Guri Unconformity. The overlying structures of these unconformities seem to have been exposed to compressional and extensional tectonic events; one during late Cretaceous is Oman Orogeny and the other during Oligocene-Miocene epoch is Zagros Orogeny. These events had a significant role in triggering Cambrian Hormuz Salt and formation salt diapirs. Furthermore, the tectonic activities and sea level variations have played an effective role in creation of the turbidities and mass transport complexes intra Mid Miocene Mishan Formation which are considered good places of gathering hydrocarbon due to having reservoir properties.
