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.)

Comments: In western sequence of central Maine trough, divided into a main body, lower member near Woodstock (schist and granofels probably equivalent to member B), upper member near Woodstock (schist and granofels probably equivalent to member C), member A (in turn divided into gray shale and massive sandstone facies, massive sandstone facies, and polymict conglomerate facies), member B (in turn divided into quartz-rich, polymictic conglomerate facies and gray shale and sandstone facies), and member C (in turn divided into quartz conglomerate, sandstone, and gray shale; impure limestone and quartz conglomerate lenses; and upper gray shale and sandstone). (ME004) Unit description from USGS GEOLEX website (ME078). GS - Greenschist facies; E - Epidote-amphibolite facies; AA - Low rank amphibolite facies; AB - Medium rank amphibolite facies; Protolith Q - Interbedded pelite and sandstone
