Detailed organic petrography analysis were conducted on drill core and cutting samples from the Nahr Umr (Middle Albian), Burgan (Lower Albian) and Ratawi (Hauterivian) formations on the Soroosh and Nowrooz fields, NW part of the Iranian sector of the Persian Gulf. The thermal maturity of the Middle Albian Nahr Umr Formation appears to have reached the top of the oil window. The underlying Burg...

three well - known source rocks of the zagros basin and the persian gulf are mesozoic in age.the jurassic sargelu, albian kazhdumi and neocomian-coniacian garau formations have charged the cretaceous reservoirs of this area. the northwest part of the persian gulf is strongly influenced by two major n-s trending paleohighs (hendijan- bahregansar-regesafid-izeh and kharge- mish) and surrounding p...

Many key aspects of early angiosperms are poorly known, including their ecophysiology and associated habitats. Evidence for fast-growing, weedy angiosperms comes from the Early Cretaceous Potomac Group, where angiosperm fossils, some of them putative herbs, are found in riparian depositional settings. However, inferences of growth rate from sedimentology and growth habit are somewhat indirect; ...

BACKGROUND Australia's dinosaurian fossil record is exceptionally poor compared to that of other similar-sized continents. Most taxa are known from fragmentary isolated remains with uncertain taxonomic and phylogenetic placement. A better understanding of the Australian dinosaurian record is crucial to understanding the global palaeobiogeography of dinosaurian groups, including groups previousl...

Pedogenic carbonate samples collected from three Lower Cretaceous (Aptian–Albian) fossil localities in Texas and Oklahoma were analyzed to develop paleoatmospheric pCO2 estimates by measuring the stable carbon isotopes of pedogenic calcite their co-existing occluded organic matter. Calcite ?13C values ranged ?10.9‰ ?4.4‰ while matter ?27.3‰ ?21.1‰. These isotope measurements combined with tempe...

Using semi-quantitative methods, the distribution of deep-water agglutinated foraminifera (DW AF) was analyzed within Latest Albian-earliest Turonian pelagic limestones famous Bottaccione standard section. The characteristic bathyal communities include forms purely "flysch-lype" assemblages and elements which are typical Upper Cretaceous abyssal environments North Atlantic. Well-established pla...

This article presents a numerical modeling application using the code TOUGHREACT of a leakage scenario occurring during a CO2 geological storage performed in the Jurassic Dogger formation in the Paris Basin. This geological formation has been intensively used for geothermal purposes and is now under consideration as a site for the French national program of reducing greenhouse gas emissions and...
