Webb Fitzwilliam Quarry


The Webb Fitzwilliam quarry was operated by Webb Granite & Construction Company. It opened circa 1829 and was abandoned by 1917. It was located half a mile south of Fitzwilliam Depot. A 7,000-foot railroad siding connected the quarry to the depot. Their product was used mainly for buildings and monuments, including the approaches and base of First Church of Christ, Scientist, Boston Massachusetts.

The granite was a muscovite-biotite granite of light, very bluish gray color and of even-grained fine texture, with feldspars and micas under 0.2 inch. Its constituents, in descending-order of abundance, were clear, colorless to translucent bluish potash feldspar (microcline and orthoclase), slightly kaolinized; clear colorless quartz with cavities and hairlike crystals of rutile; "clear to milk-white soda-lime feldspar (oligoclase), some of it slightly kaolinized and micacized; muscovite (white mica) in large scales; and biotite (black mica) in more abundant and much smaller scales. Accessory minerals include magnetite (very little), apatite and rutile. Secondary minerals include kaolin and a white mica.
