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

Porosity evolution and diagenetic history of the upper Jurassic Mozduran Formation, eastern Kopet-Dagh Basin, NE Iran

The Upper Jurassic carbonates of the eastern part of the Kopet-Dagh Basin, with thickness of 470 m, are the major gas-bearing reservoir in NE Iran. The objectives of this study are recognition of diagenetic history and estimation of porosity related to dolomitization. Based on field and laboratory study, four carbonate facies associations have been identified at the Mazdavand outcrop. Most of t...

The study of post depositional history in the Chehel Kaman formation, in the eastern regions of Kopet-Dagh, North-East Iran

The Chehel Kaman Formation of the upper Paleocene age formed from carbonate and siliciclastic sediments is located, in the Kapeh Dagh Sedimentary Basin. Two sections where considered for the purpose of research into the effective diagenetic processes of this formation. The Cheshmeh Qorban section with a thickness of 270.8m located 140km down the Mashhad – Sarakhs Highway while the Shourlog Sect...

PALYNOSTRATIGRAPHY AND PALAEOBIOGEOGRAPHY OF LOWER PALAEOZOIC STRATA IN THE GHELLI AREA, NORTHEASTERN ALBORZ RANGE OF IRAN (KOPET-DAGH REGION)

Lower Tithonian ammonites from the Chaman Bid Formation in northeastern Iran, Koppeh-Dagh Basin

The type section of the Middle and Upper Jurassic Chaman Bid Formation is in the western Koppeh Dagh Basin (Northeast Iran). It is unusually thick and contains a rather rich ammonite fauna, ranging from Bathonian to Tithonian. The ammonites described here come from a 134-m-thick interval in the upper part of member (D) in the middle part of the formation, consisting of an alternation of grey li...

Petrography and Geochemistry of the Upper Jurassic Siliciclastic Rocks Equivalent to the Mozduran Gas Reservoir in the Eastern Kopet-Dagh Basin, NE Iran

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...
