Petrology and diagenesis of the lower Mississippian Price Formation, southwestern Virginia
… objective of this study of four cores from the Lower Mississippian Price Formation was to determine the dominant controls on diagenesis and porosity as the Price sandstones are potential reservoirs for coalbed methane. Facies analyses of the cores, in combination with outcrop data from previous …

Development of cyclic ramp-to-basin carbonate deposits, lower Mississippian, Wyoming and Montana
The Lower Mississippian Lodgepole/lower Madison Formations (20-225 m thick) developed along a broad (>700 km) stormdominated cratonic ramp. Three types of shallowing-upward cycles (5th order) are recognized across the ramp-to-basin transition. Peritidal cycles consist of very shallow subtidal …

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 …

Paleontology and Paleoecology of the Nada Member of the Borden Formation (Lower Mississippian) in Eastern Kentucky
The Nada Member of the Borden Formation (Mississippian) in northeastern Kentucky was the delta platform deposit of the Borden delta. It consists mainly of iliciclastic mudstones with carbonates and siltstone interbeds. The dominant fossil groups that it contains are crinoids, brachiopods, rugose …

Analysis of Tripolitic Chert in the Boone Formation (Lower Mississippian, Osagean), Northwest Arkansas and Southwestern Missouri
… Missouri exposes a nearly complete sequence of Lower Mississippian chert-bearing carbonates deposited by a single 3rd order transgression and regression. An abundant amount of chert that has replaced limestone highlights the Boone, but little is understood about the timing and development of …

A survey of the factors which affect mining of the lower Mississippian coals in Montgomery County, Virginia
"Factors Which Affect Mining of the Lower Mississippian Coals in Montgomery County, Virginia" ie a study ot the Merrimac and Langhorne seams of the Price formation in Montgomery County, Virginia. The main reference used in the review of literature was Bulletin XXV of the Virginia Geolog1cal Survey …

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 …

Investigating evidence of high frequency glacial eustacy in the Lower Mississippian (Tournasian) Lodgepole Formation of southwest Montana : insights from conodont oxygen isotopes
… (1-8 m thick) within the Woodhurst Member of the Lower Mississippian Lodgepole Formation of southwest Montana. We combined conodont-oxygen isotopes (δ18Oapatite¬) and carbonate-carbon isotopes (δ13Ccarb) with cyclostratigraphy of Woodhurst cycles to test the hypothesis that the cycles developed in …

Taxonomy, Functional Morphology and Paleoecology of the Fenestellidae and Polyporiidae (Fenestelloidea, Bryozoa) of the Warsaw Formation (Valmeyeran, Mississippian) of the Mississippi Valley
Fenestellid and polyporid Bryozoa of the Lower Mississippian Warsaw Formation of the Mississippi River outcrop belt are represented by nine genera of Fenestellidae (three of which are new--Banastella, Cubifenestella, and Apertostella) and two genera of Polyporidae. Twenty-two previously described …

Subsurface Analysis of Mississippian Tripolitic Chert in Northwest Arkansas
<p>Over the past 70 years the Mississippian strata of Northwest Arkansas have been studied in great detail. The study area is located on the escarpment between the Boston Mountains Plateau and the Springfield Plateau where a surface occurrence of Mississippian age rock allows for access to outcrops …

Storm-dominated shelf sedimentation marginal to a delta: an example from the Devonian of southwestern Virginia and eastern West Virginia
… constitutes part of the thick Devonian - lower Mississippian Acadian clastic wedge. Sediment in the Chemung was derived from a progressively-uplifted source area to the east and accumulated in the proximal environments of an epeiric sea. Sandstones within the dominantly muddy formation are …

Geochemical Analysis of Mississippian Cherts and Devonian-Mississippian Novaculites, Southern Midcontinent Region
… of formation for the siliceous deposits in the Lower Mississippian Boone Formation and the Devonian-Mississippian Arkansas Novaculite in the southern midcontinent. Mississippi Valley-type Pb-Zn ore deposits in the Tri-State District and the Northern Arkansas District were deposited by …

Geology of the Big Walker Mountain-Crockett Cove Area, Bland, Pulaski, and Wythe counties, Virginia
… Virginia and is made up of Middle Cambrian-Lower Mississippian strata which are exposed in two separate northeast-trending strike belts. The area is bounded on the northwest by the northwestern limb of the Greendale syncline which has been overridden from the southeast by rocks of the …

Geology and mineral resources of the Goose Creek area near Roanoke, Virginia
… shales are about 800 feet thick. Silurian-Lower Devonian rocks represented by the Clinch, Clinton, and Helderberg formations are 15 (?) to 300 feet thick. Additional unclassified shales are of Devonian age. Locally Quaternary deposits of colluvium, older terrace gravels, and alluvium cover …
