The town of Boxborough was incorporated in 1783.

The rocks of Boxborough are mainly limestone with its varying shades and degrees of texture… Quartz, the most common mineral of our rocks… Some tine specimens have been found in this neighborhood, of various kinds and colors. The smooth, uniformly colored stones of the pebble-bank, white, brown, yellow or black, are mostly quartz. Erosion wears out the softer materials and leaves the hard quartz constituents behind.

Feldspar or Orthoclase, a very common mineral found in granite, is also abundant… Our varieties are white, gray, and flesh-red in color. Green is also common… Crystallized feldspar occurs in gneiss…

Black hornblende abounds in the sienitic granites and other rocks… Actinolite, a green variety of hornblende, is found in the magnesian rocks… Radiated Actinolite, olive green, consisting of collections of coarse acicular fibers, also makes its appearance in the limestone; and Asbestos, resembling the radiated, but with more delicate fibers, may be found in the same kind of rocks.

Purple Scapolite, resembling feldspar, but with a slight fibrous appearance on cleavage surface, is especially common in granular limestone. Some fine crystals are discoverable in Boxborough. It occurs massive, as well.

Boltonite, from the limestone formation, of a greenish color, is a variety of Chrysolite… Apatite, occurring in gneiss and granular limestone, has usually green, yellowish-green, bluish-green or grayish-green, crystals... Crystalline Augite occurs in Calcite Spar; specks of Serpentine, and Caleareous Spar, wine-yellow, in limestone. Spinel, Petalite and other minerals are also found.
