Summary:
Bakersville gabbro is dense, hard unmetamorphosed rock, nearly black when fresh but becoming reddish brown on weathering. Composed chiefly of plagioclase, hornblende, and pyroxene in crystals of medium size with small amounts of magnetite, epidote, and garnet as accessory minerals. Texture usually massive and granular, but locally becomes aplite. Exact age still in doubt. Some recent workers believe Bakersville may have been emplaced between Late Ordovician and Early Silurian and the Triassic.
