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.
Interlayered; minor layers and lenses of hornblende gneiss, metagabbro, mica schist, and granitic rock.
Massive to strongly foliated; minor layers of amphibolite and muscovite schist.
Megacrystic to equigranular. Churchland Plutonic Suite (Western group) - Churchland, Landis, and Mooresville intrusives.
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.
Quartz-sericite schist with metavolcanic rock, quartz-pebble metaconglomerate, kyanite-sillimanite quartzite, and garnet-quartz rock.
Strongly foliated; minor layers of amphibolite and muscovite schist.
Metamorphosed basaltic to andesitic tuffs and flows, grayish green to black. Locally includes hypabyssal intrusives and minor felsic metavolcanic rock.
Metagabbro, metadiorite, and mafic plutonic-volcanic complexes.
Metamorphosed dunite, local peridotite, serpentinite, soapstone, and other ultramafic rock. Only larger bodies shown.
Equigranular to megacrystic, foliated to massive. Includes Toluca Granite.
Interbedded felsic to mafic tuffs and flowrock.
Locally pinkish gray, massive to weakly foliated; contains hornblende.
Megacrystic to equigranular. High Shoals Granite.
Metamorphosed mafic extrusive and intrusive rock; includes hornblende gneiss, thin layers of mica schist, calc-silicate rock, and, rarely, marble. Also includes small masses of metadiorite and metagabbro.
