High-Resolution Sequence Stratigraphy of Late Mississippian (Chesterian) Mixed Carbonates and Siliciclastics, Illinois Basin
… cross-sections were constructed through the Chesterian Ste. Genevieve through Glen Dean interval which show an upward change in character from carbonate-dominated sequences bounded by caliche and breccia paleosols to mixed-carbonate siliciclastic sequences bounded by red, slickensided mudrock …

Late Mississippian (Chesterian) high-frequency climate change in the Pennington Formation at Pound Gap, KY USA.
Climate during the Late Mississippian (Late Chesterian) in the southern Appalachian Basin was characterized by periods of aridity and humidity. The Pennington Formation, exposed at Pound Gap, KY, USA records these changing climatic conditions. The climate signal, however, is partially obscured by …

Spatial Characteristics of Paleochannels in Association with the Mississippian/Pennsylvanian Systematic Boundary in Western and South-Central Kentucky
… unconformably overlie various Mississippian (Chesterian Series) rocks. Questions have been raised about the extent and orientation of paleochannels and the systemic boundary in the region. The problematical systemic boundary is quite significant in cases where marker beds are lacking or where …

Geologic Factors Affecting Hydrocarbon Occurrence in Paleovalleys of the Mississippian-Pennsylvanian Unconformity in the Illinois Basin
… unconformity, characterize the Chesterian and basal Pennsylvanian lithology, map the sub-Pennsylvanian paleogeology and delineate the pre-Pennsylvanian paleovalleys in the Illinois Basin. This study uses Geographic Information Systems (GIS) to determine the geologic factors …

Sequence Stratigraphy and Paleoecology of the Late Mississippian Little Stone Gap Member in the Appalachians of West Virginia
The upper Mississippian (Chesterian) Little Stone Gap Member of the Hinton Formation in southern West Virginia was evaluated for its lithofacies and faunal composition. Petrographic and multivariate analyses were used to provide a better understanding of the ecological factors and sequence …

Framework Grain Composition and Texture of the Wedington Sandstone Member, Fayetteville Shale, as a Provenance and Sediment Dispersal Indicator for Clastic Depositional Systems Across the Northern Arkansas Structural Platform During the Late Mississippian
… Shale is a constructive delta complex in the Chesterian section of the Late Mississippian record in Northwest Arkansas. A comparative analysis of framework grain composition between the Wedington and two other stratigraphically proximal Carboniferous sandstones: the Batesville Sandstone …

The Upper Mississippian Bluefield Formation in the Central Appalachian Basin: a Hierarchical Sequence Stratigraphic Record of a Greenhouse to Icehouse Transition
The Upper Mississippian (Chesterian) Bluefield Formation of southeastern West Virginia and southwestern Virginia is the basal unit of the Mauch Chunk Group, a succession of predominantly siliciclastic strata sourced from actively rising tectonic highlands east of the Appalachian Basin. The …

Meramecian conodonts and biostratigraphy of the (upper Mississippian) Greenbrier Limestone (Hurricane Ridge and Greendale Synclines), southwestern Virginia and southern West Virginia
… of the Greenbrier Limestone (Meramecian-Lower Chesterian), located in the Greendale and Hurricane Ridge Synclines of southwestern Virginia and southern West Virginia. The Little Valley Formation, Hillsdale Limestone and lower portions of the "Denmar-Gasper" and "Ste. Genevieve" Formations, …

Fayetteville and Imo Shales: Punctuated Upper Mississippian Shallowing Upward Sequence, Southern Ozark Region, Northern Arkansas
… Batesville Sandstone (with Hindsville Member); Chesterian Fayetteville Shale and Pitkin Limestone (with Imo Member). This interval is now interpreted as a single transgressive-regressive, unconformity-bounded, eustatic, third order cycle (Stevens and Manger, 2018). The Moorefield lowstand wedge …

State-Wide Sequence Framework of Mixed Carbonate-Siliciclastic Ramp Reservoirs: Mississippian Big Lime, West Virginia, USA
… sequence framework for Upper Mississippian (Chesterian), Big Lime carbonates, West Virginia, U.S.A.. The analysis was done using the washed coarse fraction (1-2 mm) of cuttings for each sample interval, which were separated into Dunham rock types, counted to determine relative abundance and …

Sedimentology of multistorey fluvial sandstones of the Mississippian Cypress Formation, Illinois Basin, USA
The Cypress Formation (Upper Mississippian) is the most oil-productive unit in the Illinois Basin, USA. In the central part of the basin, the Cypress Formation contains sandstones up to 60 m thick in a northeast-southwest trending belt known as the Western Belt. Thick Western Belt sandstones have …
