  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 Biostratigraphy and Paleoecology and depositional environments of Asmari Formation were studied in oil field of Pazanan (well No.121) .On base of studied done, the thickness of Asmari Formation is 334 meter and based on associated index benthic foraminifera three biozones have been selected that indicating a Late Oligocene (Chattian) to Early Miocene (Burdigalian ) age for the Asmari Formation in the studied area. In this section ,9 Microfacies were identified with different sub-environments(Open sea ,Enclosed Lagoon, Semi-enclosed Lagoon , Barrier)which were found to be deposited in a shallow marine carbonate platform in the form of a homoclinal ramp. Based on paleoecology , the lower Asmari Formation (age:chattian) by the occurrence of hyaline benthic foraminifera under normal salinity (psu35-40) in an environment ranging from aphotic to oligophotic under oligotrophic to mezotrophic condition and the middle and upper Asmari Formation by the occurrence of porcellanous benthic foraminifera ,under hypersalinity (psu45-50و more than 50 psu) in euphotic zone under eutrophic to hypertrophic conditions has been deposited in a shallow marine carbonate platform in the form of a homoclinal ramp.
