Abstract The basic structure of reservoir models is strongly affected by the stratigraphic interpretation and properties rock. estimation volume hydrocarbon accumulation will depend on accuracy predicting distributing quality. Biostratigraphic sedimentary petrologic results provide geological information to clarify stratigraphy rocks eastern margin Cuu Long delta plain trough. On basis correlat...

mammalian faunas. This model is a modified form of Vrba’s turnover-pulse hypothesis, which posits that changes in the physical environment drive speciation, extinction, and local faunal turnover (Vrba 1995a). Model 2 emphasizes the dominance of species with large population sizes and large geographic ranges through intervals of environmental change. This model arises from the literature about m...

The study of a rich Middle Oxfordian arnrnonite succession from Kachchh CW India) supplies new evidence to support the open biogeographic connections between Submediterranean and lndo - East-African Provinces. studied assemblage is precisely dated as Upper Transversarium Zone, (Middle Oxfordian), on basis representatives Perisphinctes Larche­ria , this finding being first record West-Europe...

The Pampean Region contains sedimentary sequences with abundant mammal fossil records, which constitute the chronological outline of Plio–Pleistocene South America. These classic localities have been used for more than a century to correlate other American regions. Throughout this time, series misinterpretations appeared. To understand stratigraphic significance these and geochronological situa...

New data on the distribution of fossil fish together with floral and tetrapod evidence are used to develop an internal correlation of the strata of the early Mesozoic Newark Supergroup of eastern North America. Within the Newark, we recognize five informal biostratigraphic zones, each characterized by a particular fish fauna. These fish zones are then related to other Mesozoic freshwater deposi...

As for most geological period boundaries, the Triassic–Jurassic (T–J) transition, ∼200 million years ago, was a critical juncture in Earth history during which profound biotic and environmental changes took place. Early comparisons with the end-Cretaceous extinction and the involvement of extraterrestrial impact have now largely, although not entirely, given way to more Earthbound explanations ...

Changes in sedimentary profiles and stratigraphic architecture over time lake basins are shown to be relevant markers of climate changes terrestrial palaeoenvironments. The the Priabonian (late Eocene)–early Rupelian (early Oligocene) Alès–Saint-Chaptes–Issirac saline system has been reconstructed from sedimentological, biostratigraphic magnetostratigraphic analysis outcrops well cores. As a fu...
