Named a Lower Lebanon and Upper Lebanon limestone in the Stones River group in TN. The Lower Lebanon limestone is 50 to 60 feet thick, highly fossiliferous, thin-bedded, sky-blue limestones, coarsely crystalline and abounding in calcareous remains, sometimes separated by seams of argillaceous matter. The Lower Lebanon grades into the Upper Lebanon limestone, which consists of 110 to 130 feet of grayish, sometimes brownish, and blue thick-bedded limestones, becoming thin-bedded and interstratified with occasional seams of clay in upper 15 or 20 feet. The Lebanon limestones underlie the Nashville group and are the oldest rocks in Middle Tennessee. Age is Lower Ordovician (Chazyan).

The Lebanon Limestone of the Stones River Group in central Tennessee consists of gray to bluish gray and tan, dense, fine grained limestone interbedded with coarse grained limestone and thin calcareous shale partings. Contains dolomitic and clayey burrows that weather differentially. Thickness is 74 to 118 feet. Conformably overlies the Ridley Limestone and unconformably underlies the Carters Limestone, both of the Stones River Group. The Lebanon was deposited in a quiet subtidal and normal marine environment.
