  This research focusses on the facies distribution, paleoenvironment and paleoecology of the foraminifera of the Guri Member in the northern Bandar Abbas Hinterland located in the Roydar area of southern 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

  3 - Ichnotaxonomic analysis and depositional controls on the carbonate ramp ichnological characteristics of the Deh-Sufiyan Formation (Middle Cambrian), Central Alborz, Iran

  The trace fossil assemblages from the Unit 2 of Deh-Sufiyan Formation are described for the first time from The Central Alborz Range of northern Iran,  improving the record of the assemblages in the Cambrian of the Middle East. Twenty-one ichnogenera have been identified in the Deh-Sufiyan Formation, namely Arenicolites, Bergaueria, Chondrites, Circulichnus, Cruziana, Diplichnites, Didymaulichnus, Diplocraterion, Halopoa, Helminthopsis, Gordia, Gyrophyllites, Lockeia, Monomorphichnus, Palaeophycus, Phycosiphon, Planolites, Rosselia, Rusophycus, Skolithos, and Treptichnus. Characteristics of the facies, lateral and vertical relations between these facies,  associational types of the facies and the depositional profile of the shelf transect  examined show deposition on a wave-dominated carbonate ramp. Integration of ichnologic data with sedimentologic information supports a  firm interpretation of the depositional systems and their evolution. Ethological grouping of the trace fossils resulted from the physico-chemical depositional constraints which defines the proximal-distal ichnofacies gradient pattern of the wave-dominated successions of the Deh-Sufiyan ramp. Considering the obvious deepening of the shallow marine depositional systems of wave-dominated parts of the carbonate ramp, the succession of archetypal ichnofacies can  display a bathymetric trend from deeper to shallower parts, and from lower-to-higher hydrodynamic conditions, from the  bottom to the top of the Unit 2 of the Deh-Sufiyan Formation. The identification and interpretation of the archetypal ichnofacies are  employed to further refine the sedimentary interpretations of parameters such as wave energy, substrate properties, nature of available food supply, salinity, dissolved oxygen content, and variability in sedimentation rates.

  Asmari Formation (oligo-Miocene) is the most important reservoir unit in south west of Iran oil Fields. 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
