Abstract

The Kope Formation is a located in northern Kentucky and southern Ohio. It is a major package of shale-dominated strata which lies between the limestone-dominated Point Pleasant (below) and Fairview (above) Formations. All three formations are part of the Edenian Stage (Cincinnatian Series) estimated to be 445.5 to 449.5 million years old (Upper Ordovician). The Kope and Fairview Formations are composed of cyclic beds of limestone and shale. Although the Kope Formation is treated as a single formation, recent studies suggest members and submembers better describes its cyclic nature. Three limestone samples were collected from the Kope at Lower Holst Creek, Kentucky, and analyzed for fossil and rock types. Two samples are likely from the Fulton Submember, whereas the third is from younger strata. Based on the literature, the samples likely formed in a storm-dominated environment. We correlate our samples with cycles identified in the Kope Formation.
