Stoneville Formation - conglomerate, sandstone, and mudstone, lenticular and laterally-gradational bedding.
Felsic Mica Gneiss - interlayered with biotite and hornblende gneiss and schist.
Metagraywacke and Muscovite-Biotite Schist - metagraywacke (biotite gneiss) interlayered and gradational with muscovite-biotite schist; minor marble and granitic rock.
Pine Hall Formation - sandstone, mudstone, and conglomerate, yellowish orange to brown.
Mica Schist - Garnet, staurolite, kyanite, or sillimanite occur locally; lenses and layers of quartz schist, micaceous quartzite, calc-silicate rock, biotite gneiss, amphibolite, and phyllite.
Cow Branch Formation - mudstone with minor sandstone, gray, laterally-continuous bedding. Intertongues with Stoneville and Pine Hall formations.
Shelton Granite Gneiss (429 my) - poorly foliated; lineated granitic to quartz monzonitic gneiss.
Mafic Metavolcanic Rock - metamorphosed basaltic flows and tuffs, dark green to black; interbedded with felsic and intermediate metavolcanic rock and metamudstone.
Biotite Gneiss and Schist - 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.
Granitic Rock (265-325 my) - megacrystic to equigranular. Castalia, Lillington, Medoc Mountain, Sims, Contentnea Creek (?), and Elm City (?) intrusives.
Metamorphosed Granitic Rock (680-710 my) - massive to foliated, locally mylonitic. Beech, Crossnore, Brown Mountain, Lansing, and other granitic rocks.
Amphibolite - equigranular, massive to well foliated, dioritic to basaltic dikes and sills; variably metamorphosed.
Metamorphosed Granitic Rock (455-540 my) - equigranular to megacrystic, foliated to massive. Includes Toluca Granite.
Phyllite and Schist - minor biotite and pyrite; includes phyllonite, sheared fine-grained metasediment and metavolcanic rock.
Rich Acres Formation - Norite, metagabbro, and diorite.
Felsic volcanic and volcaniclastic rocks.
Fork Mountain Formation - Quartzose mica schist, garnet-biotite gneiss, calc-silicate quartzite, and melange.
