Summary:
Named the Cannon limestone for Cannon Co., TN. Consists of several hundred feet of limestone on the east flank of the Nashville dome. It thins rapidly to the west and finally wedges out in the vicinity of Nashville. Unit overlies the Hermitage formation and underlies the Eden group; it is equivalent in age to the interval spanned by the Bigby, Flanagan, and Perryville limestones, and the Catheys formation. The Cannon is of Middle Ordovician (Trentonian) age.

Summary:
Geographically extended the Cannon Limestone to northwestern GA and included it in the Nashville Group (middle formation of three). Consists of medium dark gray calcilutite and calcarenite in well defined beds generally 2 to 6 inches thick that contains chert lenses and nodules; It is fossiliferous and contains TETRADIUM, brachiopods, bryozoans, and gastropods. Thickness is 110 to 120 feet. Unit overlies the Hermitage Formation and underlies the Catheys Formation, both of the Nashville Group.
