Source and diagenesis of Middle Jurassic marine mudstones, Kopet-Dagh Basin, NE Iran
Middle Jurassic fluvio-deltaic and turbiditic mudstones of the Kashafrud Formation, are important hydrocarbon sources in the gas-rich Kopet-Dagh Basin, northeast Iran. Clay mineral assemblages are important for interpretation of sediment provenance and for understanding burial diagenetic cementation in sandstones. The clay mineral assemblages in mudrocks in two areas, Saleh-Abad and Senjedak, w...

Sequence 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 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 کاملanalysis of middle jurassic course grain deposits, in the east of kopet-dagh basin, iran
kashafrud formation, siliciclastic strata, middle jurassic in age, commences with basal fluvio conglomerates. the strata are described in terms of 3 facies association (conglomerate, sandstone and mudstone), which were deposited in a fluvio-deltaic and turbities environments. the basal kashafrud strata at 2 areas (8 sections), in the eastern kopet-dagh basin, consist predominantly of boulder to...
