Oil and gas resources of the Cincinnati arch, Ohio, Indiana, Kentucky, and Tennessee

Ordovician Point Pleasant/Utica-Lower Paleozoic Total Petroleum System—Revisions to the Utica-Lower Paleozoic Total Petroleum System in the Appalachian Basin Province

“…Some Lexington Limestone wells in Kentucky and Trenton Limestone wells elsewhere were not included in any TPS. Some researchers have suggested that, in addition to the Upper Ordovician strata, the Devonian Chattanooga Shale may have been a source for hydrocarbons in Trenton Limestone wells in the Cumberland saddle area in Tennessee (Ryder, 1987).…”

Re‐Os isotope systematics in carbonates from Serpent Mound, Ohio: Implications for Re‐Os dating of crustal rocks and the osmium isotopic composition of Ordovician seawater

“…The carbonates are generally fine-grained, tan to gray, fossiliferous limestones [Gaddis, 2001]. Although no data are available for the total organic carbon in these samples, they are clearly organicrich; the Lexington Limestone and Black River Group are associated with significant oil and gas production in the Cincinnati Arch Province [Ryder, 1994] and abundant asphalt has been found in samples from the Serpent Mound cores and vicinity [Carlton et al, 1998;McFarland, 1999]. Detailed descriptions of the core samples have been published previously [Carlton et al, 1998;Gaddis, 2001;Baranoski et al, 2003].…”
