Wilcox Formation

Lustrous to rusty-weathering biotite-muscovite (┬▒chloritoid) schist and retrograde coarse-garnet schist; probably is the retrograde equivalent of charnockitic garnet-rich feldspathic quartz gneisses of the eastern Adirondacks. Locally contains mappable quartzite, garnet quartzite, calc-silicate gneiss, and marbles, mapped separately. Part of the aluminous schists and gneisses of the Washington Gneiss and Wilcox Formation and related rocks. Mount Holly Complex paragneiss. Rocks of the Green Mountain and Lincoln Mountain massifs and eastern domes.
