The (Thomas) McCarthy quarry was located about half a mile northwest of North Acton railroad station, "at the top of a small knoll". It opened in 1890 and was idle as of 1916. It measured in 1910 150 by 80 feet and 20 feet deep. Their product was used for buildings, monuments, and curbing.

The granite was a biotite-muscovite-quartz monzonite of light to medium bluish-gray color and of fine to very fine, obscurely gneissoid texture, with feldspars under 0.2 inch and mica up to 0.1 inch, but mostly under 0.05 inch. Its constituents, in descending order of abundance, are translucent to milk-white soda-lime feldspar (oligoclase-andesine), slightly kaolinized; in nearly equal amount, clear bluish potash feldspar, (microcline and probably orthoclase) ; clear colorless quartz, strained, in places granulated and with cavities; biotite (black mica); and muscovite (white mica), also stringers of secondary fibrous muscovite. Accessory: Magnetite, apatite, and zircon. Secondary : Epidote, carbonate, muscovite, and kaolin.
