Abstract :
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.
