Summary:
Report is based on reexamination of stratigraphy of sub-Eden beds of Ordovician age along Ohio River at its crossing of Cincinnati Arch. Review of the literature reveals several sources of confusion in nomenclature and correlation. Study of detailed section at West Covington and Carntown, KY and Point Pleasant, OH. Rogers Gap [member of Cynthiana] formation, uppermost member of the Mohawkian, and overlying Fulton shale, lowermost member of the Cincinnatian, are faunally indistinguishable in this area. They appear to be lithologic facies of same time-rock unit. Faunal and lithologic evidence indicates advisability of extending the Cincinnatian series downward to embrace the Cynthiana formation, rather than including this formation in the Mohawkian.
