Summary:

Redoak granite occurs in Charlotte and Mecklenburg Cos., VA. [According to Rand McNally Commercial Atlas, town for which unit is named is spelled Red Oak (two words).] Unit is medium-grained light-gray biotite granite, rather quartzose, containing about equal amounts of orthoclase and plagioclase feldspars. Small masses or areas of coarse porphyritic granite that occur in Redoak granite in vicinity of Buffalo Lithia Springs are named Buffalo granite.

Summary:

Red Oak pluton described in text as light-gray, medium-grained, foliated granite to granodiorite. As used in this report, is equivalent in part to the Red Oak [Redoak] granite as defined by Laney (1917) and Horton and others (1993). Shown on map as Red Oak granite. Age not indicated.
