Campbell Creek Previous HitMarineNext Hit Zone: Its Extent, Component Facies, and Relation to Coals of Kanawha Formation in Southern Kanawha County, West Virginia

Ronald L. Martino

Recent widening of the West Virginia turnpike has provided extensive exposure through the Campbell Creek Previous HitmarineNext Hit zone, enabling a much clearer view of its stratigraphy and sedimentary facies. Nineteen stratigraphic sections were measured and described in detail in the Belle and Cedar Grove 7.5^prime quadrangles.

Previous HitMarineNext Hit-influenced stratigraphic intervals are distinguished and correlated by use of both body and trace fossils. Productid and spiriferid brachiopods, and pelmatozoan ossicles are commonly associated with the nodules as well as with scour-fill, cross-stratified sandy limestones. In addition, a diverse suite of shallow Previous HitmarineNext Hit trace fossils is developed. Some of the more common ichnogenera include Olivellites, Asterosoma, and Teochichnus.

Rather than a single, laterally persistent Previous HitmarineNext Hit band, the Campbell Creek limestone represents the lowermost of two or three nodular limestone zones that are sporadically developed over a stratigraphic interval of 16 m or more. Upper and lower divisions of the Campbell Creek Previous HitmarineNext Hit zone are recognizable along Cabin Creek south of Chelyan where Previous HitmarineNext Hit-influenced strata are separated by a 4-8 m thick interval consisting of coal, dark-gray rooted shales and siltstones, and channel and crevasse splay sandstones.

The base of the Previous HitmarineTop zone begins 10-12 m above the No. 2 gas coal and overlies distributary channel and overbank facies.

A depositional model integrates both body and trace fossils, lithology, sedimentary structures, and paleocurrent data. A lower delta plain mosaic of environments includes distributary channels, crevasse splays, coastal swamps, tidal creeks and flats, and bays.
