The stratigraphy and economic potential of Permo-Pennsylvanian strata in southwestern North Dakota
<p>This study of the Fermo-Pennsylvanian Minnelusa Group in North Dakota was designed to clarify the stratigraphy, illustrate association of depositional environments, and to relate the geologic history and economic potential of these strata.</p> <p>The Minnelusa Group is defined here to include …

Architectural Models for Lower Pennsylvanian Strata in Dickenson/Wise County, Southwest Virginia: A Reservior Case Study
The lower Pennsylvanian, coal-bearing, siliciclastic strata in Dickenson/Wise counties of southwest Virginia were deposited in continental to marginal marine environments influenced by high-amplitude relative sea level fluctuations. Coal-bearing siliciclastics of the eastern facies belt are …

Sequence Stratigraphy and Architecture of Lower Pennsylvanian Strata, Southern West Virginia: Potential for Carbon Sequestration and Enhanced Coal-Bed Methane Recovery in the Pocahontas Basin
… and enhanced coalbed methane recovery of lower Pennsylvanian coal-bearing siliciclastic strata within the Bradshaw CBM field, southern McDowell County, WV. Analysis of outcrop, gamma ray and density logs, and eight cross-sections within the study area reveals a hierarchy of bounding …

Origin, Architecture, and Thermal State of the Lackawanna Synclinorium, Pennsylvania: Implications for Tectonic Evolution of the Central Appalachians
… thus, deep burial (6--9 km) by post-Pennsylvanian strata was not required for anthracitization. Field observations, fluid-inclusion studies, and illite-crystallinity analysis suggest that Alleghanian fluid flow was stratigraphically controlled.

Paleozoic stratigraphy as an ore control of hydrothermal, base-metal, sulfide deposits in New Mexico
… is applied on a regional scale to Paleozoic strata in thirteen mining districts with hydrothermal base-metal deposits in a 35,300 square mile area or southwest New Mexico.</p> <p>The rocks at the stratigraphic position of the ore-zones are characterized as massive- to thick-bedded with less …

Thermal and Diagenetic Evolution of Carboniferous Sandstones, Central Appalachian Basin
… indicate that burial of Lower and Upper Pennsylvanian strata of the Appalachian Plateau in West Virginia exceeded 4.4 km during the late Permian and occurred at a rate of ~100 m/m.y. Exhumation rates of ~10-30 m/m.y. from maximum burial to present depth were constrained using published …

Tectonics of the Wolf Creek Fault Zone, southern Illinois: A consequence of Late Paleozoic transpression and transtension at the southeastern end of the Ste. Genevieve Fault System
… several tilted fault blocks of Mississippian strata; beds in these blocks now have dips between 15° and 21°. This tilting occurred prior to deposition of the sub-horizontal beds of the Pennsylvanian-age Caseyville Formation, so the contact between Mississippian and Pennsylvanian strata in the …
