facies and sequence stratigraphy of tirgan formation in abgarm and sirzar sections, northeastern kopet-dagh basin

Late Barremian-Early Aptian Ammonites from the Tirgan Formation, Kopet-Dagh Sedimentary Basin, NE Iran

During the recent field research on the Tirgan Formation in the west of Kopet-Dagh sedimentary basin, ammonite assemblages were obtained from the carbonate strata of this formation. This new finding is important for stratigraphical purpose. In this research, 3 genera belong to Heteroceras, Deshayesites and Cheloniceras? as well as one uncertain genus belongs to Turkmeniceras are determined. The...

DEPOSITIONAL HISTORY AND PALEOGEOGRAPHY OF THE LOWER PALEOCENE REDBEDS IN EASTERN KOPET-DAGH BASIN NORTHEASTERN IRAN

depositional environment and sequence stratigraphy of mixed siliciclastic-carbonate deposits of aitamir formation (bazangan area- east of kopet dagh basin)

the aitamir formation (albian- cenomanian) in the kopet- dagh basin consists of fine to medium grained sandstone, siltstone, shale and limestone. its lower contact with the sanganeh formation is gradual and its upper contact with the abderaz formation is unconformable. field and petrographic studies of the aitamir formation in artenj and ghorghoreh sections, located in bazangan area- east of ko...

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...

depositional environment and provenance of the shurijeh formation sandstones (neocomian) in the abgarm village, east of kopet-dagh basin

in this study, depositional environment and provenance of sandstones of the surijeh formation (lower cretaceous) in the abgarm section in the kopet-dagh basin are investigated. analysis of sedimentary facies in this section shows that there are two clastic (continental and coastal plain) and two carbonate (coastal plain) facies associations are present. the results of modal analysis and geochem...

Significance of ichnofossils in high resolution sequence stratigraphy: Upper Maastrichtian, Kopeh- Dagh Basin, NE Iran

This study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the Kalat Formation (Upper Maastrichtian) in the Central Kopeh- Dagh Basin (NE Iran), Dareh-Gaz section. Field studies and petrography of these deposits led to recognize four lithofacies and nine subfacies that formed in the tidal flat (lithofacies A), lagoon (lit...
