Summary:
Linville metadiabase named in Mitchell Co., western NC. Consists of altered dull yellowish-green diabase and gabbro. Near line of Blue Ridge, Linville is associated with Montezuma schist, Flattop schist, and Cambrian quartzites, and in several narrow bands south of Blue Ridge with Cranberry granite.

Summary:
Linville Diabase consists of medium- to fine-grained, blue-green, green, or gray, massive or schistose metadiabase. Amphibole grains or plagioclase laths visible on some weathered surfaces. Occurs as dikes and sill-like bodies intrusive into Grandfather Mountain Formation. Relations of Linville Metadiabase to metabasalts of Montezuma Member of Grandfather Mountain Formation indicate that diabase was intrusive equivalent of basalt; therefore, Linville is late Precambrian in age.
