Granite pegmatite - Oxford pegmatite field. Originally opened by George "Shavey" Noyes and Tim Heath, about 1894. Locality was obtained from Shavey's sixth cousin, Isaac Patch Noyes. Worked briefly by Loren Merrill and Arthur Valley in 1921-1922 for the benefit of Kenneth K. Landes, then a Harvard University student. Landes' dissertation, Paragenesis of the Granitic Pegmatites of Central Maine (American Mineralogist, 1925, v. 10, p. 355-411) was based on this quarry and the Bennett Quarry in Buckfield and his thesis revolutionized ideas about how pegmatites crystallize. (Note: The non-pegmatite species reported occur in the metamorphic rock (Patch Mountain member of Sangerville Formation) hosting the pegmatite.)
