PALEOCLIMATE DURING DEPOSITION OF THE GREATER TWILIGHT PARK CONGLOMERATE, UPPER DEVONIAN, SOUTHEAST NEW YORK
… the continent of Laurentia, primarily during the Devonian Period. This created the southward propagating Acadian Orogeny. Formation of the basin and the cratonward-prograding Catskill clastic wedge promoted deposition of the Devonian siliciclastic rocks of the Catskill Mountain region of …

Revision of the Upper Devonian in the Central-Southern Appalachian Basin: Biostratigraphy and Lithostratigraphy
The Upper Devonian of the central-southern Appalachians Valley and Ridge province of Virginia lacks stratigraphic resolution, revised formal nomenclature, and detailed biostratigraphic data. Eight of the most complete sections available in a three thousand square mile area were used to build a …

Stratigraphy and depositional environments of the Three Forks Formation (Upper Devonian), Williston Basin, North Dakota
<p> The Three Forks Formation (Upper Devonian) is present in the subsurface in the western two-thirds of North Dakota and is generally conformable with the underlying Birdbear Formation and the overlying Bakken Formation. </p><p> The Three Forks attains a maximum thickness of 265 feet (81 meters) …

Petrology, geochemistry, diagenesis and depositional environment of the Upper Devonian - Lower Carboniferous Exshaw Formation, northwestern Alberta.
The Upper Devonian (Famennian)-Lower Carboniferous (Tournaisian) Exshaw Formation is a thin, laterally extensive organic-rich petroleum source rock. It is one of Canada's most important petroleum source rocks and is a major contributor to the Lower Cretaceous Mannville heavy oil accumulations in …

Sedimentology, ichnology, and stratigraphic architecture of the upper Devonian-lower Mississippian Bakken Formation, west-central Saskatchewan
The Upper Devonian-Lower Mississippian Bakken Formation has recently become a prolific producer of light gravity oil in southeastern Saskatchewan since the advent of horizontal drilling and multi-stage hydraulic fracture technologies, which has resulted in an increase in geological studies within …

A new member of the zygopteridales from the lower Upper Devonian (Frasnian) of Ellesmere, N.W.T., Arctic Canada
… fossil plant is described from the Lower Upper Devonian of southern Ellesmere. This plant occurs as an element of an Archaeopteris dominated flora preserved in sediments of the Nordstrand Point Formation (mid-late Frasnian) at Bird Fiord. The plant demonstrates a pinnate vegetative system …

Marine offshore to alluvial plain transitions within the "Chemung"-Hampshire interval (Upper Devonian) of the southern central Appalachians
The Upper Devonian "Chemung" and Hampshire Formations of the southern Central Appalachian basin constitute the upper strata of an eastward thickening wedge of elastic sediment. The sediments comprising the "Chemung" and Hampshire, deposited on a low-gradient marine shelf and alluvial plain, …

Influence of the West Virginia Dome on paleocurrent patterns in the Upper Devonian-Lower Mississippian Price Formation in the Central Appalachians
Upper Devonian-Lower Mississippian sedimentation was influenced by a positive area known as the West Virginia Dome located in the Central Appalachians of West Virginia. Paleocurrent data collected from the Price Formation demonstrates the significance of the dome on paleoflow patterns. Exposures in …

Subdivisions and correlations of the Tully Formation (Upper Devonian) in New York State and Pennsylvania on the basis of a statistical and stratigraphical analysis of selected conodonts.
… than the base of the Assise de Fromelennes (Upper Devonian, France) and is furthermore correlated with the lowest part of the to 1alpha zone (Upper Devonian, Germany). The conodonts of the Tully Formation are considered to be similar to those of the lower Geneseo Shale, the Alto Formation …

Orbital-scale fluctuations in continental weathering flux and continental ice-volume during greenhouse and icehouse climate intervals : evidence from oxygen and neodymium isotopes
… greenhouse intervals: the Late Silurian and Late Devonian. The first study (Chapter 1) explores whether glacio-eustasy was the driver for orbital-scale shallowing-upward cycles developed in Late Silurian and early Late Devonian tropical and subtropical greenhouse climates. Two intra-cycle δ18O …

Improving the simulation of a waterflooding recovery process using artificial neural networks
… producing horizon in the field is the Upper Devonian Gordon sandstone, which is characterized by severe heterogeneity due to the depositional environment. Using available core and log data and geological analysis, a reservoir characterization study was done. A preliminary reservoir …

Paleoenvironmental interpretation of the Guilmette Formation near Ely, Nevada
<p>Two sections of the Upper Devonian Guilmette Formation in White Pine County, Nevada, were measured and sampled to determine its paleoenvironmental and depositional history. The Guilmette was deposited predominately during a transgressive phase that was interrupted by minor regressions. The …
