Summary:
The Gilliam Creek Limestone, informally named by Sanders (1952), is here named in the Greendale syncline in Hawkins and Grainger Cos., TN, where Mississippian strata previously named Newman Limestone by Hardeman and others (1966), are isolated from the Newman Limestone in the Newman Ridge syncline. The Gilliam Creek consists of finely laminated argillaceous limestone and calcarenite with chert lenses and nodules. Overlies the Clifton Creek Limestone; sharply underlies the Fisher Creek Formation. Correlates in part with the Ste. Genevieve Limestone. Age is Mississippian.
