Named Stones River group for exposures on Stones River near Nashville, TN. Consists of 240-260 feet of fossiliferous limestones divided into three entities (ascending): Stones River beds, Lower Lebanon limestone, and Upper Lebanon (Carters) limestone. The basal or Stones River beds are 75 feet thick, blue and brownish-blue limestones, mostly fine-grained and thick-bedded, some strata abounding in dark flinty layers. Lower Lebanon limestone is 50-60 feet thick, highly fossiliferous, thin bedded sky-blue limestones, coarsely crystalline and abounding in calcareous remains, sometimes separated by seams of argillaceous matter; grades into Upper Lebanon limestone which is 110-130 feet thick of grayish, sometimes brownish, and blue thick-bedded limestones, becoming thin-bedded and interstratified with occasional seams of clay in upper 15-20 feet. The Stones River underlies the Nashville group and is the oldest rocks in middle Tennessee.

Geographically extended the Stones River Group into the subsurface of the Warrior basin in MS. The group is divided into the (ascending) Stones River Dolostone and Stones River Limestone [this is in violation of the North American Stratigraphic Code]. Dolostone is gray to tan, greenish gray, very fine to finely crystalline, sandy and argillaceous in parts, and contains some bentonite. Limestone is gray to light tan, micritic to finely crystalline, argillaceous at top. Thickness is 503 to 2215 feet. Overlies the Knox Group. The Stones River Group is of Middle Ordovician (Whiterockian) age.
