Clay mineralogy of the Jurassic-tertiary sedimentary rocks of the Kopet Dagh Basin (Northeastern Iran): Implications for paleoclimate and sedimentary environment

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...

Sedimentology, mineralogy and sedimentary geochemistry of the Late Quaternary sedimentary sequence of Gavkhoni Playa by looking at the paleoclimate

The sediments of the Playa Lake are sensitive indicators of local climates that any change in climate, hydrology, and sedimentary environment will cause changes in the physical and chemical properties of the sediments. These sediments create a valuable and important archive with high resolution to examine these changes in the past. One method of studying climate change during quaternary and oft...

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

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...

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...
