Precambrian metapyroxenite containing nepheline vein mineralization. Davis Hill is the locality for giant nepheline crystals of Moyd (1990). The Davis Quarry, of similar name, is NOT the locality of the giant nepheline crystals and that quarry is located near the York River Skarn Zone to the south.
