The section between the 7 and 11 electric markers in the Aratu Stage of the Recôncavo Basin (Lower Cretaceous) has been studied in order to perform a stratigraphic analysis. This section bear reservoir rocks known as Imbé, Cambuqui and Miranga sandstones. It produces petroleum in fields like Miranga, Araçás, Taquipe, Miranga Norte and Imbé.The isopach map showed a general trend of increased subsidence for south and southeast. A series of structural lows surround the platform region known as Quiricó High. Southwestward, the Taquipe Canyon is an indication of the lake deepening in that region.In

The paleogeography of the late Pliocene is poorly studied. Meanwhile, more detailed studies of the paleogeography of the late Pliocene are of great importance for understanding the historical and geological development of the Pliocene-anthropogenic structural stage within the Southern Caspian and Eastern Azerbaijan. We have created a paleogeographic model based on the generalization of a huge amount of factual material - regional geophysical works, stratigraphic-paleontological data and complex sedimentological research.Late Upper Pliocene seas are characterized by their salinization and the d

AbstractInterpreting the deposits of ancient epeiric seas presents unique challenges because of the lack of direct modern analogs. Whereas many such seas were tectonically relatively quiescent, and successions are comparatively thin and punctuated by numerous sedimentary breaks, the Mesoproterozoic Belt Basin of western North America was structurally active and experienced dramatic and continuous subsidence and sediment accumulation. The Grinnell Formation (ca. 1.45 Ga) in the lower part of the Belt Supergroup affords an opportunity to explore the interplay between sedimentation and syndeposit

Two very different plate-tectonic models have been proposed to explain the development and emplacement of the Robert Mountains allochthon (RMA) onto the North America craton during the Late Devonian-Early Mississippian Antler Orogeny.

In the other, the eugeoclinal strata of the RMA were deposited on the continental rise of western North America within a closed back-arc basin.

Abstract The Cretaceous Ferron Sandstone is a fluvial-deltaic system that is superbly exposed along the western flank of the San Rafael Swell in east-central Utah. The Ferron consists of fluvial, near shorezone, and shallow-marine strata that were deposited along the active margin of an evolving foreland basin. The 180-m-thick (590-ft) Ferron Sandstone forms an east- to northeast-thinning clastic wedge that is bounded by marine strata and pinches out over the distance of 40 km (25 mi). Numerous local transgressive intervals further subdivide the Ferron into 10-20-m (30-60-ft) thick successions

The sedimentation rate progressively decreased throughout the deposition of the Last Chance Delta.

The opportunity to study many of these stratal units in detail on outcrop has led to the further division into numerous parasequences.
