The volcanogenic Mount Rogers Formation and the overlying glaciogenic Konnarock Formation : two late Proterozoic units in southwestern Virginia /

The Mount Rogers Formation, largely continental rift-facies volcanic rocks, is redefined, and the name Konnarock Formation is introduced for the overlying glaciogenic deposits of diamictite, arkose, and laminite. Four rhyolite members of the Mount Rogers are named and described.
