Foliated to massive, granitic to quartz dioritic; biotite gneiss and amphibolite common.
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.
Weakly foliated to massive, contains plagioclase megacrysts and, rarely, larger megacrysts of quartz and feldspar.
Massive to foliated, granodioritic, migmatitic.
Interlayered with amphibolite.
Variably foliated, variably migmatitic, and granitic to quartz dioritic in composition
Thin to thick layered sillimanite-mica schist and sillimanite-bearing muscovite-biotite schist
Variably layered biotite-quartz-feldspar gneiss having porphyroclasts and/or porphyroblasts of plagioclase and locally of quartz and potassium feldspar
Layered biotite-quartz-feldspar gneiss
