In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...

this study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the kalat formation (upper maastrichtian) in the central kopeh- dagh basin (ne iran), dareh-gaz section. field studies and petrography of these deposits led to recognize four lithofacies and nine subfacies that formed in the tidal flat (lithofacies a), lagoon (lit...

The Campo section in the Spanish Pyrenees is classical for shallow-water Paleocene-Eocene Thermal Maximum (PETM) studies. Despite extensive work last decades, stratigraphic location of onset negative carbon isotope excursion (CIE), and hence Paleocene/Eocene (P/E) boundary, remains a matter considerable debate section. Here we present new biostratigraphic, sedimentological carbon-isotopic data ...

The present study focuses on facies analysis and the reservoir characteristics of the Asmari Formation in the Aghajari oilfield (located in the Zagros fold-thrust belt, southwest Iran), and how they are linked to depositional environments and reservoir characteristics. This formation consists of about 380 m carbonates with some siliciclastic intercalations. Based on the integration of 1200 m of...

The Raduha section represents a continuation of the research Anisian Strelovec Formation in Kamnik-Savinja Alps. was deposited during on drowned Serla Dolomite carbonate platform restricted probably outer ramp environment associated with an intraplatform basin. base is represented by dolostone breccia containing angular lithoclasts shallow-marine origin. This followed alternations laminated and...

The middle Santonian-lower Campanian carbonate-mud dominated succession deposited in the northeastern margin of South Iberian Ramp (La Cañadilla Fm, NE Spain) shows a complex set interfingered facies developed low-energy and low-gradient shallow-marine to coastal environment. Three belts characterize environment reconstructed this work: (1) shallow marine lagoon by radiolitid rudist limestones ...

The Sa’adi Formation is a part of the late Cretaceous period in Santonian-Campanian stage that represents potential hydrocarbon-bearing reservoir across many oilfields Mesopotamian Basin, South Iraq. was divided into two main parts as stratigraphy sequence. It consists chalky limestone with argillaceous upper and marly lower part. considered an important stratigraphic unit marked by petroleum s...

Abstract In the central-eastern Sirt Basin, enigmatic Intisar domal structures host significant hydrocarbon accumulations. These have been commonly interpreted as pinnacle reefs/bioherms occurring in open-marine basinal environment. Generally, are mainly characterized by situ carbonates. The current study challenges reef/bioherm model examining one of terms biostratigraphy, microfacies and depo...
