Palynofacies-based sequence stratigraphy of the Upper Cretaceous strata (Abderaz Formation) in east of Koppeh-Dagh Basin, Northeast of Iran
The Upper Cretaceous strata were studied in a composite stratigraphic section named here Padeha-Baghak section in east of Koppeh-Dagh basin, north east of Iran. In this study, palynostratigraphy, palynofacies and depositional environment history of Abderaz Formation were integrated with sequence stratigraphy. Determination of sea level history and sequence units of the Abderaz Formation using s...
متن کاملfacies and sequence stratigraphy of tirgan formation in abgarm and sirzar sections, northeastern kopet-dagh basin
tirgan formation with lower cretaceous age (barremian-aptian) in the kopet-dagh basin consists of carbonate and siliciclastic rocks (calcareous shale and sandstone) which conformably lay between siliciclastic rocks of shurijeh formation below, and marly sarcheshmeh formation at the top. in this study, tirgan formation in two stratigraphic sections of abgarm (77 m in thickness) and sirzar (46 m ...
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...

15 صفحه اولUpper Miocene Salt Layer in the Western Mediterranean Basin
THE problem of salt deposits in a present deep-sea basin has been discussed recently in the case of the Atlantic Oceanl. In this article we present new data on the salt layer in the Western Mediterranean Basin. In the Balearic Basin and the Ligurian Sea, anticline structures and dornes disturbing the upper part of the sedimentary cover have been reported by Alinat and Cousteauz, Menard et aL3, ...
