  The Dariyan Formation (Aptian- Albian) is one of the important hydrocarbon reservoirs in theSW of Iran. In this investigation, microfacies, depositional environment and sequence stratigraphyof the Dariyan Formation have been studied in the Sivand and Dashtak anticlines in the north ofShiraz. The thickness of the Dariyan Formation in the Sivand section is 330 meters and in theDashtak section is 263 meters. It mainly consists of limestone and shale interbeds. The lowercontact of the Dariyan Formation with the Gadvan Formation is gradational and the upper contactwith the Kazhdumi Formation is disconformity. Field and microscopic studies of the DariyanFormation have led to recognition of 3 groups and 11 microfacies related to open marine, barrierand lagoon environments. These facies groups were formed in a rimmed shelf carbonate platform.Vertical facies variations indicate the presence of one 3rd sequence. The lower part of TST is in theGadvan Formation and the upper boundary of HST with Kazhdumi Formation is SB1 Manuscript profile

  Abstract In the study of the Dariyan Formation (Shoaiba Fm.) in one of the southeastern fields of the Persian Gulf, the sedimentary environment and biostratigraphy of these deposits were investigated on the cores which obtained from this formation. In the studies of the sedimentary environment, seven carbonate microfacies and one mixed carbonate-clastic microfacies were identified, which represent the deposition of the Dariyan Formation in four facies belts, including the inner ramp, middle ramp, outer ramp and deep basin. Also, uniform facies changes, the absence of rudists forming large reefs and the replacement of Lithocodium algae with them indicate the homoclinal carbonate ramp environment. In biostratigraphic studies based on foraminifera and calcareous algae, five biozones were identified, which represent the Aptian age for this formation. By combining the geological studies, the results obtained from the routine analysis of the cores and the evaluation of petrophysical logs, the reservoir quality of this formation was also studied, which indicated the good reservoir quality in parts of these deposits and especially the layers bearing Lithocodium algae. Based on these studies, the Dariyan Formation is one of the important reservoir formations in the east of the Persian Gulf. Manuscript profile
