In this research, petrographic and geochemical (major and trace elements) characteristics of siliciclastic rocks of the Mozduran Formation in the eastern Kopet-Dagh Basin have been carried out in order to reveal their provenance such as source area paleoweathering, parent rock composition and tectonic setting. Mozduran Formation is mainly composed of limestone and dolomite, with minor amounts o...

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...

The Kopet Dagh mountains in NE Iran exhibit a 7-km-thick continuous sedimentary sequence recording detritus from exposed surrounding terranes the last 175 Ma. This work presents multi-disciplinary geochronologic and provenance analysis an attempt to identify date major geologic events along northern segment of Tethys reconstruct regional tectonic history Gondwana-related rifting until Alpine or...

calcareous nannofossils in boundary of tirgan and sarcheshmeh formations at qalezo section have been studied. this section is situated in the west of kopet-dagh basin. in this study 35 nannoplankton species of 17 genera were identified. according to the first occurrence of index species and fossil assemblages two calcareous nannofossil biozones (cc7-cc8) of sissingh (1997) have been recognized....

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...

the sanganeh formation crops out throughout the kopeh-dagh basin and is mainly composed of shale and marl with interbeds of siltstone and limestone. in this study, the sanganeh formation, with 550 meter thickness, has been studied at north of the sanganeh village in eastern parts of the basin. according to distribution of organic matter content, four palynofacies types are identified. the main ...

The Kordkanlo Basin, one of the Atrak sub-basins, located in the northeastern of the Ghoochan city, the Khorasan Razavi Province; is situated in Kopet Dagh geologic zone. The overall objective of this study is to evaluate the morphotectonic effects on the drainage network of the basin, using morphometric indicators. In this research, morphometric quantitative indicators of hypsometric integral ...
