Lithofacies, provenance, and diagenesis of jura-cretaceous strata of the Northern Bowser Basin, British Columbia
Lithofacies, provenance, and diagenetic studies of more than 3 km of Late Jurassic to mid-Cretaceous silicilastic sediments exposed in the northern Bowser Basin (northern British Columbia) record the tectonic development of the Canadian Cordillera. Strata are divided into the undivided Bowser Lake …

Lithofacies Determination in the Willesden Green and South Pembina Duvernay Formation: Creation, Characterization, and Correlation
This study proposes a set of lithofacies in the Southern West Shale Basin of the Duvernay Formation that characterize variation at core and thin section scales, correlate with conventional well logs and can be further related to geochemical data, elastic properties, elastic property-based …

Petrophysical lithofacies modeling of the upper Pennsylvanian Cline Shale in the Midland Basin, West Texas.
The Cline Shale is an upper Pennsylvanian interval of interstratified organic-rich shale, inorganic shale, and allochthonous carbonate beds, and is currently an active unconventional exploration target within the Midland Basin of west Texas. This study compares core-observed depositional facies to …

Late Pleistocene lithofacies, paleolimnology and ostracode fauna of kettles on the Illinoian till plain, Illinois, U.S.A
The response of sediment, vegetation and aquatic environments to climate change during the last glacial--interglacial--glacial intervals were investigated from fossiliferous successions in four breached kettle basins in south-central Illinois. The thickest measured successions of lacustrine/paludal …

Reconstructing lithofacies of the Norphlet Formation (Jurassic) as potential exploration targets: Little Cedar Creek and Brooklyn Fields, southwest Alabama
… resulted in the deposition of four main lithofacies: basal shales, conglomerates and conglomeratic sandstones, the Denkman Sandstone member, and a redbed succession. Additionally, the presence of playa lakes allofor deposition of evaporites associated with the Norphlet Formation. The …

Depositional environments and paleogeography of the Winnipeg Group (Ordovician), Williston Basin, North Dakota
… The Hawkeye Valley Member consists of two lithofacies: a red-bed lithofacies and a green quartz wacke lithofacies. The red-bed lithofacies consists of two lithotypes: a red quartz arenite and a red clayshale. The Hawkeye Valley Member reaches a maximum thickness of 128 feet (39 m) in …

The geology and hydrocarbon potential of the Dawson Bay Formation carbonate unit (Middle Devonian), Williston Basin, North Dakota
… The carbonate unit can be subdivided into five lithofacies on the basis of characteristic fossil fauna, flora, and other lithologic features. In ascending order, the carbonate lithofacies are: lithofacies B (brachiopod-echinoderm wackestones and mudstones), lithofacies C (stromatoporoid …
