Abstract

The QOM FORMATION (Oligo-Miocen) is the most important hydrocarbon source in central Iran. Deposition of the QOM FORMATION in Band-e-Amir section in northwest of SAVEH was studied for stratigraghy survey, FACIES analyze and environmental interpretation. The studied area was located in structural-sedimentary zone in central Iran. The QOM FORMATION has a lot of FACIES variations. At the time of transgression, gypsum and marl were deposited and at the time of regression, limestone and marl were sedimented. Therefore, in most areas, the QOM FORMATION can have alternation of marl and limestone with intercalations of gypsiferous marl and gypsum. This formation has important role as a reservoir rock, source rock and cap rock. Band e Amir Section in northwest of SAVEH have 198 meter of thickness. Assessment of thin sections of The QOM FORMATION in Band-e-Amir section led to recognition of three FACIES groups related to lagoon (A), barrier (B) and open marine environments. Lagoonal FACIES consists of packstone and wackestone textures. Reef FACIES have formed coral boundstones and barrier deposits. Open marine FACIES have shown turbidity and basinal characteristics. Lack of inertidal FACIES and abundance of talus and turbidity FACIES are the characteristics of the QOM FORMATION in the studied area. Assessment of lateral and vertical changes of FACIES show that the QOM FORMATION in Band-e-Amir section were deposited in a carbonate RIMED SHELF.
