High resolution sequence stratigraphy of late Mississippian carbonates in the Appalachian Basin
The late Mississippian carbonates in the Appalachian Basin, U.S.A., were deposited on a huge, south-facing ramp during long-term Mississippian transgression that formed the Mississippian supersequence. The St. Louis- to Glen Dean interval consists of up to twelve fourth-order depositional sequences …

High-Resolution Sequence Stratigraphy of Late Mississippian (Chesterian) Mixed Carbonates and Siliciclastics, Illinois Basin
… tide-dominated Illinois basin during the Late Mississippian greenhouse to icehouse transition. Detailed, lithologic cross-sections were constructed through the Chesterian Ste. Genevieve through Glen Dean interval which show an upward change in character from carbonate-dominated sequences …

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 …

The controls on reservoir continuity within the late Mississippian Elkton Member at Caroline Field, Central Alberta, Canada.
… 68.3 mmbbl of recoverable oil reserves from the Mississippian Elkton Member (recovery factor of approximately 38%). Additional residual oil reserves at Caroline may be produced through enhanced recovery if carefully guided by a detailed stratigraphic framework. This study focuses on two …

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 …

Stratigraphy and Depositional Characterization of the Moorefield Shale (Middle-Late Mississippian) in its Type Area, Northeastern Arkansas (Eastern Arkoma Basin)
… Shale a lowstand wedge succeeding the Early Mississippian (Osagean) Boone Limestone conformably and overlain conformably by the Hindsville Limestone/Batesville Sandstone. The unit contains a basal brown-black limestone and succeeding brown-black phosphatic shale. The Moorefield Shale was …

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
… 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 (older) and the Basal …

Terrestrial paleoecology of distal deltaic environments of the upper Mississippian Bluefield, Hinton and Bluestone formations of southwestern Virginia and southern West Virginia
… Virginia, that expose the Early Carboniferous (Late Mississippian) Bluefield, Hinton, and Bluestone Formations, were measured. Geological structures and paleontological occurrences were recorded. In situ rooted plants were compared with transported plant and animal assemblages from fluvially …

Community as assemblage in the Late Cahokian hinterlands
… in the material constituents of Cahokian and Mississippian life. Likewise, community was deeply embedded in the continued success, and eventual decline and abandonment, of Cahokia. I argue that after Cahokia’s Stirling phase (1100 – 1200 CE) florescence, Cahokian community became …

Geology of the Blacksburg area, Montgomery County, Virginia
… thrust over younger Cambrian, Ordovician, and Mississippian rocks. The more or less age autochthonous rocks are the Cambrian dolomites of uncertain and Copper Ridge Formation, the Ordovician Chepultepec, Longview, and Mascot-Kingsport Formations, the Middle Ordovician limestones, and the …

Regional cementation associated with unconformity-sourced aquifers and burial fluids, Mississippian Newman Limestone, Kentucky
Aquifer-related cements may be differentiated from deeper burial cements by trace elements, cathodoluminescence, staining, and fluid inclusion analysis in the Mississippian Newman Limestone, eastern Kentucky. Aquifer cements are nonferroan, and show a nonluminescent to dull to nonluminescent to …

Aspects of Cyclic Sedimentation in the Upper Mississippian, Mauch Chunk Group, southern West Virginia and southwest Virginia
Late Mississippian, Mauch Chunk Group strata constitute a westward-thinning clastic wedge of strata up to 1000m thick that developed in the Central Appalachian Basin over a ~ 7 million year time interval. Included within the Mauch Chunk Group are multiple incised-valley fills and a distinctive …

Revisiting Magee: A Mississippian Mound Center Site
… Phillips (1970) dates the site within the Late Mississippian period (A.D 1200-1500), and more specifically to what is now understood to be the Lake George phase (A.D 1350-1500) based on diagnostic artifacts. In the winter of 2015, the site was revisitied and a controlled surface collection …

Structure and Stratigraphy of a Complex Anticlinal Feature, Backbone Anticline, Arkoma Basin, Arkansas
… formed in the Ouachita foreland during the late Mississippian and Pennsylvanian periods (about 290-to 330 million years ago). The basin developed in response to convergent tectonic boundaries that closed obliquely from west to east associated with Ouachita orogenic event. The Backbone …

Cementation and dolomitization of Mississippian limestones, Kentucky and Virginia
The Mississippian Newman Limestone (0-30 m thick) in eastern Kentucky contains pink-staining, aquifer-related cements (up to 750 ppm Mn+2); up to 1000 ppm Fe+2; δ¹⁸ -7.5 to -6.8 per mil; δ¹³C 1.7 to -6.8) that is non-luminescent (low Fe and Mn) in the recharge area, but becomes uniformly dully …

Paleopathology at the Shady Grove Site (22QU525): A Study of Health in the Upper Yazoo Basin During the Middle Mississippian Period
<p>The Mississippian Period (AD 1000-1539) is characterized by increasingly sedentary populations, mound building, ranked societies, and intensified agriculture. As agriculture spread throughout the Eastern Woodlands, it led to widespread health consequences, including poor nutrition and increased …
