Depositional History of Jahrum
(Zagros) and Ziyarat (Alborz) Formations Based on Distribution of Benthic Foraminifera.
The limestone of the Jahrum Formation consists one of the reservoir intervals in the Zagros basin in Iran.
Review of the literature revealed that integrated studies (lithostratigraphy, biostratigraphy, depositional environment and sequence stratigraphy of the Jahrum Formation have not been carried out in the Bandar Abbass Area.
Finally a 3D depositional model has been proposed for the Jahrum Formation.
Review of literature indicates that many studies have been done on the Jahrum Formation of the Dezful Embayment because of oil field spreading.
