Nov 1, 1973 · The highly dolomitized Main Limestones of approximately Mississippian age, which crop out in South Wales, are classified according to their Ca Mg ratio values. The results based upon the Ca Mg ratio determination of these rocks permitted their classification into six major categories, namely: (1) limestone; (2) slightly dolomitized limestone; (3) dolomitic limestone; (4) calcitic dolostone; (5 ...

Mississippian hill, as these patches usually do. North, east, and south the Mississippian surface falls a hundred feet or more. In a hill close by, the Lower Mercer limestone is found only 50 feet above the Maxville—an interval that is usually 120 to 150 feet between the Lower Mercer limestone and the base of the Pennsylvanian.Mississippian Subperiod, first major subdivision of the Carboniferous Period, lasting from 358.9 to 323.2 million years ago.The Mississippian is characterized by shallow-water limestone deposits occupying the interiors of continents, especially in the Northern Hemisphere. These limestones exhibit a change from calcite-dominated grains and cements to aragonite-dominated ones.Abstract Mississippian Meramec reservoirs of the Sooner Trend in the Anadarko (Basin) in Canadian and Kingfisher Counties (STACK) play are comprised of silty limestones, calcareous siltstones, argillaceous calcareous siltstones, argillaceous siltstones, and mudstones.

This study is focused on correlating fracture types and intensity to distinct petrophysically significant facies and to an established sequence stratigraphic framework in the unconventional carbonate reservoirs of the "Mississippian limestone" of the U.S. midcontinent region.C.J. Appelseth, Reservoir Characterization of Mississippian Strata in Central and Eastern Oklahoma Utilizing Core and Wireline Logs; Elizabeth Elium, Combining Sequence Stratigraphy with Artificial Neural Networks to Enhance Regional Correlation and Determination of Reservoir Quality in the "Mississippian Limestone" of the Mid-Continent, USAIn northwestern GA, northeastern AL, and southeastern TN, Bangor Limestone caps a 300-450-m-thick Mississippian carbonate sequence. In northwestern GA, the Bangor is subdivided into carbonate-rich lower and upper members and a clastic-rich middle member, while correlative strata in west-central AL are assigned to the clastic Parkwood Formation.

The upper Mississippian-Pennsylvanian Mauch Chunk-Pottsville clastic wedge prograded westward and southwestward from the Pennsylvania salient over Mississippian limestone. The southwestern limit of the Mauch Chunk-Pottsville clastic wedge is more » overlapped in the Virginia recess by the oppositely directed Pennington-Lee clastic wedge.In eastern Kentucky, in the narrow outcrop belt along the Pottsville (Cumberland) Escarpment at the western edge of the Appalachian basin, the unconformity is marked by paleochannels as much as 200 ft deep and, locally, by paleokarst topography developed on underlying Mississippian limestone.
