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.
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, granitic to quartz dioritic; biotite gneiss and amphibolite common.
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.
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.
Cross-bedding and graded bedding common, locally conglomeratic; interlayered with metasiltstone and phyllite.
Monzonitic to granodioritic; inequigranular.
Finely laminated to thin layered; locally contains massive gneiss and micaceous granule conglomerate; includes schist, phyllite, and amphibolite.
Poorly layered to massive; megacrysts of microcline and quartz; local mica schist, amphibolite, and biotite gneiss
Interlayered; minor layers and lenses of hornblende gneiss, metagabbro, mica schist, and granitic rock.
Weakly foliated to massive, contains plagioclase megacrysts and, rarely, larger megacrysts of quartz and feldspar.
"Fish scale" schist and phyllonite, graphitic; interlayered with feldspathic metasandstone, marble lenses.
Vitreous quartzite, white to light gray; interbedded sandy metasiltstone and slate.
Massive to foliated, locally mylonitic. Equivalent to Brown Mountain Granite.
Sericitic, conglomeratic, locally cross-bedded; interlayered metasiltstone and slate.
Metamorphosed dunite, local peridotite, serpentinite, soapstone, and other ultramafic rock. Only larger bodies shown.
Phyllitic to schistose, contains euhedral to subhedral phenocrysts of gray quartz and pink potassic feldspar. Resembles quartzite and meta-arkose.
Schistose to massive, amygdaloidal; interlayered with metasedimentary rocks. Includes Montezuma Member (metabasalt) in upper part.
Metadiabase, greenstone, and amphibolite dikes and sills; massive to schistose.
Tentatively correlated with Grandfather Mountain Formation.
Locally contains thin bedded iron-bearing dolomitic marble; interlayered with phyllite, metagraywacke, and meta-arkose.
Unconformity; abundant white potassic feldspar megacrysts in finely banded biotite schist, locally calcareous; interlayered with quartz-feldspar schist, calcareous biotite schist, phyllite, black slate, calcareous quartzite, sulfidic greenstone, and siliceous tuff.
