The carbonate and terrigenous sedimentary sequence of the Padeha and Bahram formations (late Givetian- late Frasnian) with a total thickness of 126 m have a gradational and conformable contact at Baghin region of W Kerman in Central Iran. The terrigenous facies are mainly consisting of sandstone and shale deposited in the beach environment. The carbonate rocks including dolomite and limestone have tidal flat, lagoon and barrier (shoal) facies. Based on the index conodonts and brachiopods the late Givetian- late Frasnian age is suggested for this studied section. The conclusions of petrographical studies indicated a shallow carbonate platform of ramp type for these sediments. The stratigraphical study of the Bahram formation at the studied area resulted in identifying 3 sedimentary sequences of the third order, which according to the microfacies and conodonts consist of the following items. The first sequence begins with transgression at the base of the Lower falsiovalis – Upper falsiovalis zone (TST), with continuation of transgression, it reaches the maximum flooding level (mfs) indicated by the coral bindstone facies in a shoal environment and then is followed by the relevant HST parasequences. The second sequence begins at transitans – punctata zone, and finally the TST parasequences with ooid grainstone in a shoal environment reaches the maximum flooding level (mfs) at the Lower rhenana zone and ceases, and then is followed by the HST parasequences. The third sedimentary sequence begins at the base of Upper rhenana-? linguiformis zone, its maximum flooding surface (mfs) is in the middle of the Upper rhenana -?linguiformis zone and is identified by the spiculate wackestone facies in an open sea environment, and it is followed by the HST parasequences. These sequences are limited by the sequential boundaries of SB1 and SB2 types.
