Depositional Environment and Sequence Stratigraphy of the Oligocene-Miocene Deposits North and East of Dehdasht, Izeh Zone, Zagros Basin, Iran
In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...
متن کاملSequence stratigraphy and depositional environment of the Oligocene deposits at Firozabad section, southwest of Iran based on microfacies analysis
The Asmari Formation was deposited in the foreland basin of southwest Iran (Zagros Basin). Carbonate sequences of the Asmari Formation consist mainly of large benthic foraminifera along with other skeletal and non-skeletal components. Three assemblage zones have been recognized by distribution of these large foraminifera in the study area that indicate Oligocene age (Rupelian-Chattian). Absence...
متن کاملDepositional environment, diagenesis, sequence stratigraphy and geochemistry of Lower Cretaceous carbonate unit (K1) of Kuh-khangormas, Tuyserkan (Sanandaj-Sirjan Zone)
Abstract Lower Cretaceous carbonate units of the Kuhzation, karstification and dolomitization, studies of 40 samples of these carbonate units indicated aragonite as original mineralogy in closed to semi-closed diagenetic system.
متن کاملDepositional History and Sequence Stratigraphy of the Tirgan Formation (Barremian – Aptian) in the Zavin section, NE Iran
The Tirgan Formation (Barremian – Aptian) is exposed in the Kopet Dagh in northeast Iran. One stratigraphic section in Zavin was measured with a thickness of 110 meters. This Formation in section consists of three parts (including lower carbonate, limy shale – marl and upper carbonate rocks). Based on the study of 94 thin sections, 10 carbonate and 2 siliciclastic lithofacies have been identifi...
متن کاملAn Integrated Geophysical Approach for Porosity and Facies Determination: A Case Study of Tamag Field of Niger Delta Hydrocarbon Province
Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...
