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 ...

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...

Over the years, shale oil has been at leading edge of exploration and also become hotspot reserve increases for various fields. The Permian Lucaogou Formation in Jimsar Sag less extensively researched terms of, among others, lithologic interpretation fine-grained mixosedimentite, identification classification sedimentary microfacies, sweet spot evaluation. present study identifies characteristi...

In this paper, the microfacies of thin-layer sand outer front facies are described by homogeneous unit thickness classification in past, plane distribution single body and connection relationship between different types roughly understood; From two aspects vertical single-stage identification fine description sedimentary belt map applying energy microfacies, is divided into 6 9 kinds combinatio...

Fan deltas of the Lower Cretaceous area in Saihantala sag, Erlian Basin have been identified as major petroleum exploration opportunities. The sedimentary evolution is, however, still debatable, which hinders insights into its controlling factors. This research employed new core observations, thin section and grain size analyses 28 wells Saidong sub-sag, together with numerous borehole seismic ...

The Devonian to Carboniferous sinters of the Drummond Basin, Australia, are among the oldest well established examples of fossil subaerial hot springs. Numerous subaerial and subaqueous spring deposits are known from the geological record as a result of the occurrence of economic mineral deposits in many of them. Some are reported to contain fossils, but very few have been studied by paleobio...

in order to microfacies studies of the cretaceous deposits, a section called korkouh was selected in kerman province in central iran area. the korkouh is on the bidou formation with angular unconformity and underlain by paleogene conglomerates with an erosional surface. the studied section basically contains lime and dolomitic limestone with the thickness of 146 meters with new fossils such as ...

the asmari formation is a thick carbonate sequence in zagros foreland basin. it was deposited during oligocene – early miocene ages. in order to interpret the depositional environment and sequence stratigraphy, firuzabad section were compared with 4 sections of asmari formation in the zagros basin. four different sub environments were identified in the asmari formation based on microfacies anal...

In the Late Paleozoic paleogeography, the Laibin area, South China, locates in the south-eastern margin of the Laibin-Heshan isolated carbonate platform. One global stratotype section for The Guadalupian–Lopingian (G/L) (The end of the Mid-Permian) transition is located in the Tieqiao section in Laibin area, which is regarded as appropriate one for the study. Based on the analysis, seven facies...
