Oriskany Formation, Appalachian Basin (16)

Western Pennsylvania, Eastern Ohio, and Eastern Kentucky

Comments on Geologic Parameters

16 Rock Mineralogy:

Stow (1938) and Rosenfeld (1954) presented summaries of the mineralogy of the Oriskany. A number of master's theses also present the results of mineralogic analyses. These theses, which appear on GEOREF computer searches, would require visits to respective universities for examination and copying because they are generally not available through Interlibrary Loan services. The results of Stow (1938) were used for the GIS. Although his results appear thorough and systematic, there is a noticeable lack of calcite in his results. Personal observation of the Oriskany Sandstone in numerous outcrops in the central Appalachian Basin, as well as the results of Rosenfeld (1954) and Diecchio and others (1984, their fig. 4), demonstrates that the Oriskany interval commonly contains shell material and calcite cement and grades into sandy limestone in places.
