Finely laminated to thin layered; locally contains massive gneiss and micaceous granule conglomerate; includes schist, phyllite, and amphibolite.
Inequigranular, locally abundant potassic feldspar and garnet; interlayered and gradational with calc-silicate rock, sillimanite-mica schist, mica schist, and amphibolite. Contains small masses of granitic rock.
Unconformity; contains paragneiss and granitic to quartz monzonitic orthogneiss; locally schistose and mylonitic. Locally includes tectonic slices, infolded remnants, or recrystallized equivalents of the Grandfather Mountain Formation. Equivalent to the Wilson Creek Gneiss.
Monzonitic to granodioritic; inequigranular.
Foliated to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.
Interlayered; minor layers and lenses of hornblende gneiss, metagabbro, mica schist, and granitic rock.
Vitreous quartzite, white to light gray; interbedded sandy metasiltstone and slate.
Garnet, staurolite, kyanite, or sillimanite occur locally; lenses and layers of quartz schist, micaceous quartzite, calc-silicate rock, biotite gneiss, amphibolite, and phyllite.
Foliated to massive, locally conglomeratic; interlayered and gradational with mica schist, muscovite-biotite gneiss, and rare graphitic schist.
"Fish scale" schist and phyllonite, graphitic; interlayered with feldspathic metasandstone, marble lenses.
Equigranular to megacrystic, foliated to massive. Includes Toluca Granite.
Feldspathic quartzite, white to yellowish gray. Minor silty slate, feldspathic metasiltstone, and metaconglomerate in lower part.
Light gray, fine grained, massive, locally thin bedded or ribboned. Thin beds of phyllite.
Equigranular, massive to well foliated, interlayered, rarely discordant, metamorphosed intrusive and extrusive mafic rock; may include metasedimentary rock.
Weakly foliated to massive, contains plagioclase megacrysts and, rarely, larger megacrysts of quartz and feldspar.
Poorly foliated; interlayered with biotite augen gneiss.
Metamorphosed dunite, local peridotite, serpentinite, soapstone, and other ultramafic rock. Only larger bodies shown.
