Summary:

Named the Conway schist in western MA, southeastern VT, and southwestern NH for Conway, Franklin Co., MA. Consists of dark graphitic mica schist with biotite, garnet, staurolite, voisite, and many beds of dark impure limestone and sandy quartzite. Thickness is probably 5000 feet. Overlies the Goshen schist and underlies the Leyden argillite. Unit is probably equivalent to the Amherst schist to the east. The Conway is of Silurian(?) age.
