the study area is located in the northeast of iran. miankuhi formation is 500m thick and comprises homogeneous shales, brown granular sandstone and siltstone. in this study, 45 samples were taken from miankuhi shales and sandstones in order to determine their tectonic origin by using a polarizing microscope. samples were analysed by x-ray fluorescence (xrf) method to determine their chemical co...

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 basin extended in the north and north east of iran and consists of marine strata from middle jurassic to paleogene time. abtalkh formation is one of the thickest lithostratigraphic units of cretaceous in the kopet-dagh basin and is composed of light gray, green to bluish marl and silty marl. the abtalkh formation conformably overlies the marls and chalky limestones of the abderaz...
