Sillimanite-rich aluminous schist composed mainly of sillimanite, biotite, muscovite, and minor quartz
Variably foliated, variably migmatitic, and granitic to quartz dioritic in composition
Gneissic biotite granite to granodiorite
Variably layered biotite-quartz-feldspar gneiss having porphyroclasts and/or porphyroblasts of plagioclase and locally of quartz and potassium feldspar
Variably interlayered, containing subordinate layers of amphibolite and sillimanite-mica schist
Aluminous muscovite-biotite schist, locally having subordinate amphibolite layers
Biotite-quartz-plagioclase gneiss and interlayers locally containing hornblende, sillimanite, microcline, and muscovite
Well foliated, banded to non-banded biotite granitoid gneiss or gneissic granitoid; cuts Seneca thrust fault
Equigranular to inequigranular granite gneiss and augen gneiss, undivided
Layered biotite-quartz-feldspar gneiss
Thin to thick layered sillimanite-mica schist and sillimanite-bearing muscovite-biotite schist
Gneissic biotite granite to granodiorite of Starr pluton and nearby satellite plutons
Amphibolite and interlayered gneiss, hornblende gneiss and minor mica schist
Chauga River Formation and Poor Mountain Formation, undivided
Interlayered with amphibolite.
Massive to foliated, granodioritic, migmatitic.

Poorly foliated; interlayered with biotite augen gneiss.
Biotite granitoid augen gneiss having distinctive microcline augen; monzonite to granodiorite composition
Foliated to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.
Garnet, staurolite, kyanite, or sillimanite occur locally; lenses and layers of quartz schist, micaceous quartzite, calc-silicate rock, biotite gneiss, amphibolite, and phyllite.
Monzonitic to granodioritic; inequigranular.
