This paper focuses on the Frasnian reefal development in eastern border of Dinant Synclinorium. Classical sections from Durbuy–Bomal area were reevaluated for lithostratigraphy, microfacies, magnetic susceptibility (MS) and diagenesis. As regards middle succession, studied is located a transitional zone between Pont de la Folle/Philippeville Formations Moulin Liénaux/Grand Breux Formations. suc...

Purpose. The work studies Sinjar formation (upper Paleocene lower Eocene) within the Bazyan anticline in Sulaimaniyah region (northeastern Iraq). facies analysis is based on petrographic study of limestone deposits and essential to identify their nature. sediments that formed have a high content skeletal granules which include small amount red algae residues unicellular organisms-foraminifera. ...

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 bioz...

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...

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. ABSTRACT This study identifies, characterizes, and analyzes the pore systems of the Niobrara Formation, and explores the linkage between measurable rock properties and the observed pore...

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 ...

Four supergiant and numerous giant gasfields have been discovered in the Southwest Iran which produce from Permian-Triassic carbonates belong to the upper member of Dalan Formation and Kangan Formation. In this research a detailed biostratigraphic, microfacies and sequence stratigraphic study of the late Middle Permian to Triassic successions was undertaken from 850 thin sections prepared from ...

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 rock successions of the Chia Gara Formation were studied at two surface sections (Barsarin and Rania) from North-Eastern Iraq. detailed sedimentological study reveals that formation consists basically thin-bedded black limestone, dolomitic marly bituminous shales, Ammonitic limestone. petrography results showed various petrographic components as Ammonites, calcispheres, radiolarian, silicat...
