Summary:

The Cranberry-Mine Layered Gneiss is here named in the Elk River massif in North Carolina. It is equivalent to the Shoals Gneiss in Virginia. These older layered country rocks were mapped as part of the Cranberry Granite of Keith (1903) which is here renamed the Cranberry Suite and restricted to the plutonic rocks of the Elk River massif. Age is Middle Proterozoic.
