Summary:

The Murfreesboro Limestone of the Stones River Group in central Tennessee consists of mainly dark gray, very fine grained, massively bedded limestone that locally contains laminations, mud cracks, intraformational conglomerate, chert, and dolomitized burrows. Unit is the oldest formation exposed in the Central Basin of Tennessee (70 feet exposed thickness) and underlies the Pierce Limestone of the Stones River Group. The Murfreesboro was deposited in a shallow, probably restricted marine environment like an inner shelf lagoon and tidal flat.
