Lewis, J S

The Catskill deltaic sequence (Upper Devonian-Lower Mississippian) is inadequately mapped and subdivided in the subsurface of northern West Virginia (central Appalachian basin). Stratigraphic interpretations are often hindered by the liberal use of drillers' names for noncontemporaneous gas-bearing sandstones. Base-line analysis of 275 ..gamma..-ray logs permits the resolution of lithostratigraphic units in this sequence. Stratigraphic cross sections graphically display relative thickness variations of reservoir sandstones and document the intertonguing facies of the Catskill deltaic sequence that are attributable to cyclic marine transgression and regression, and/or to changing sedimentation or subsidence rates in the basin. Contrary to some previous studies, this study indicates these strata are best interpreted within the context of deltaic sedimentation. More specifically, stratigraphic and sedimentologic evidence suggests deposition in a wave- and storm-dominated deltaic complex.
