Pg. 2. Honaker limestone [in Virginia, Honaker dolomite]. Varies in character from blue flaggy limestone to dark impure limestone and massive gray dolomite. Thickness 900 to 1,000 feet. Overlies Russell formation and underlies Nolichucky shale. West of this quadrangle [Tazewell], the Honaker limestone is subdivided by a small band of calcareous shale (Rogersville shale) into two distinct limestones, the upper of which has been named Maryville and the lower Rutledge limestone. In passing eastward the Rogersville shale becomes more and more calcareous until on western edge of this quadrangle the three blend into a single limestone with about same thickness as the aggregate farther west. Age is Middle Cambrian.
[Named from exposures at Honaker, Russell Co., southwestern VA. Extends into northeastern TN and western NC.]
