The Upper Bajocian- Lower Bathonian succession in the Kopet-Dagh Basin of NE Iran represents fluvio-deltaic to turbidite deposits. The Kashafrud Formation provides an excellent opportunity to study the interplay between deep-water sedimentation and syndepositional tectonic subsidence (or uplift) in the region. The effects of these processes caused sea-level changes, variation in depositional se...

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...

kashafrud formation, siliciclastic strata, middle jurassic in age, commences with basal fluvio conglomerates. the strata are described in terms of 3 facies association (conglomerate, sandstone and mudstone), which were deposited in a fluvio-deltaic and turbities environments. the basal kashafrud strata at 2 areas (8 sections), in the eastern kopet-dagh basin, consist predominantly of boulder to...
