The indexed microfacies are carefully determined through studying of 230 thin sections.This research shows that the indexed microfacies are mudstone, wackestone, packstone, prainstone and the amount of microfacies elements such as bioclasts, pellets, extraclasts and intraclasts. They are varied in different parts of the studied sections and the total amount of bioclasts in the section is more than other elements. The abundance of benthic bioclasts represents the regression of the basin from the open sea into the sub tidal and intertidal zone. Manuscript profile -

11 - Paleoecology of Early to Middle Miocene Deposits (Guri Member) and Sedimentary Environment, SE Zagros Zone, Roydar, Iran

The Guri Member is 570 meters thick and composed of limestone, argillaceous limestone and marl. The distribution of the foraminifera in the study area indicates the existence of three biozones ranging from early to middle Miocene in age. Based on petrographical studies, depositional textures and fauna, eight microfacies were identified. The paleoecology, lithology and environmental interpretations were characterized by an open marine environment with an upward, gradually shallowing trend. Additionally, three distinct depositional settings were identified: tidal flat, inner ramp and middle ramp. Microfacies (MF) 1, representing a distal middle ramp setting, was characterized by the occurrence of hyaline, benthic and planktonic foraminifera. MF2 and MF3 were characterized by the occurrence of Miogypsina, Elphidium and red algae. They represent a deeper low energy in the wave base of a middle ramp setting. MF4 was characterized by an abundance of rotaliids and red algae representing a proximal middle ramp environment. MF5 and MF6 were identified by the occurrence of large and small porcelaneous benthic foraminifera representing a shallow-water inner ramp setting. MF7 and MF8 were characterized by the occurrence of gastropods and bivalves in a shallow-water setting of tidal flats influenced by both wave and tidal processes. Palaeolatitudinal reconstructions based on skeletal grains suggest that the Guri Member existed in tropical waters within a carbonate ramp. Manuscript profile -

The Rage-Safid oil field is one of them. This field is located in Dezful Embayment. In several studies, there are still someuncertainty about microfacieses and depositional environment of the Asmari formation in Rag-e-safid oil field.There for according to petrographical study of thin sections supplied of cores and cutting samples (2138 thinsections with 7 wells) and comparison of associated constituent facieses with standard microfacies types ofcarbonate ramps of Flugel (Flugel, 2004) and facies belts of Buxton and Pedley (Buxton and Pedley, 1989), 13carbonate microfacieses and 2 non carbonate microfacieses is investigated. The microfacieses are in five groupfacieses (depositional sub environment) that consist of open marine (group O), shoal or bar (group B), lagoon(group L), intertidal (group I) and supratidal (group S). The sub environment ascribed to a carbonate platformramp. Manuscript profile -

Its lower contact (section a) is abrupt andmild unconformity with lower red formation. Its upper contact (section f) is gradual and concordant with upperred formation. Besides sampling, lithology changes, stratigraphy, geomorphology of stone units was examined.The results led to drawn the stratigraphy log of Qom Formation in the studied area. Petrography and microfaciesstudies together with field evidences led to recognition of eight carbonated microfacies in different parts of QomFormation. This microfacies lied on the tidal, barrier, lagoon and open marine environments. The study of faciesand their succession in the mentioned area and compare with modern and old sedimentary environment showsthat Qom Formation was deposited in a warm marine environment. Also, the facies of Qom Formation in thestudied area was deposited in a carbonated ramp environment Manuscript profile -

The studied area is located at the Birg Mountain, south of Saryan city,Southern Khorasan province.The thickness of the studied sequence is 188m which mostly consists of spong spicule-bearing bioclasticwackestone, intraclastic/oolitic wackestone, peloidal packstone, intraclastic packstone, intraclastic/bioclasticwackestone and algal wackestone. According to the petrographic studies, skeletal fragments of Ghaleh DokhtarFormation consist shell fragment, brachiopod, spong spicule, .algae, corals, and foraminifera and also peloids,intraclasts and oncoids as non skeletal particles. Totally, seven microfacies belts were recognized which could bereferred to open marine, barrier and lagoon belts of a rimmed-shelf carbonate platform. Manuscript profile -

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 -
