Summary:

The Hills Mountain Granulite Gneiss is here named in the Lovingston massif in the central Blue Ridge, VA. It consists of gray, medium-grained, hypersthene-bearing quartzo-feldspathic gneiss with granoblastic texture and poorly developed segregation layering. It forms most of the country rock around and roof-pendants in the Archer Mountain pluton. The contact zone between the gneiss and the pluton consists of a zone of migmatitic granulite gneiss. Age is Middle Proterozoic.

Summary:

Hills Mountain Granulite Gneiss was mapped by Bloomer and Werner (1955) as Lovingston Granite as opposed to surrounding Lovingston Gneiss, and by Bartholomew (1977) as poorly layered granulite gneiss.
