mauddud member with the age of late albian to cenomanian is equivalent to the lower sarvak formation in the southern persian gulf and adjacent area. in this work, microfacies, depositional environment, and diagenetic processes affected the mauddud member in a field in the persian gulf are investigated. based on the studies of available cores and thin sections of 3 wells, five types of microfaci...

the badamu formation (upper toarcian-middle bajocian) mainly consists of limestone and shale and has is cropped out in east of iran. the badamu formation conformably overlays shemshak formation and is underlaid sharply by hojedk formation in kerman area and is underlaid gradually by baghamshah formation in tabas and southern khorasan areas. the aim of this work is petrographical study of rocks ...

In this research, the microbiostratigraphy and depositional environmental implications related to the Surgah Formation at the northern flank of the Kuh-e Sepid anticline in the Lorestan Basin are discussed. A study of small planktonic foraminifera from the 101-m-thick Surgah Formation led to the identification of three Turonian–Santonian biozones: (1) Helvetoglobotruncana helvitica, (2) Margino...

A mature understanding of the sandstone gas reservoir in the Xiaoheba Formation in the southeastern Sichuan Basin remains lacking. To assess the reservoir characteristics and the origin of the high-quality reservoir in the Xiaoheba Formation, this paper uses systematic field investigations, physical property analysis, thin section identification, scanning electron microscopy and electron microp...

The studied area covers two outcrops they are located within Sulaimaniya, northeastern of Iraq (Rania and Sargelu sections). Sections in village Unstable Shelf, High Folded Zone, including Surdash anticline, while Rania Sectionis city near Hanjira the Shaweri anticline. carbonates represent major microfacies constitute lime mudstone microfacies, wackestone Calcisphere-Posidonia submicrofacies, ...

The current study deals with microfacies and the depositional environment of Lower Cretaceous Sarmord Formation at selected sections in Sulaimani Erbil Governorates, northern Iraq. alternates rhythmically between yellowish grey marly limestones black marls. These lithologies are observed all studied Petrographic investigation this based on 240 thin demonstrated that carbonate constituents mainl...
