The Trenton Limestone consists of skeletal sand and organic buildup facies that were deposited on a carbonate ramp under shallow-water open-marine conditions. Petroleum reservoirs occur in the Trenton only where hydrocarbon entrapment in both structural and stratigraphic traps preserved porosity in a regional dolostone.
