A town incorporated in 1737. The bedrock geology consists of metamorphic and igneous rocks of the Connecticut Valley Terrane, mostly oceanic metasediments accreted during the Ordovician Taconian Orogeny. A belt of Ordovician Rowe and Ratlum Mountain schists and granofels (the former including altered ultramafic bodies) underlies the northwest and western parts of town. Another belt of schist underlies the southeastern corner, in this case mostly the Devonian-Silurian The Straits Schist. These two schist belts are separated by an intrusion of Devonian Nonewaug Granite.

"found intimately associated with vivianite where it occurs in small greenish black masses, and in stalactitic form with a radial fibrous structure. The surface of the incrustations are composed of indistinct microcrystallized individuals of rockbridgeite" Januzzi and Seaman (1976) |
| β Sarcolite Formula: Na4Ca12Al8Si12O46(SiO4,PO4)(OH,H2O)4(CO3,Cl) Habit: fibrous Colour: white Description: According to Januzzi and Seaman (1976), X-ray studies were conducted by Professor Horace Winchell at the mineralogical laboratories at Yale.

Concentrated in the outer edges of triphylite pods with rockbridgeite. Some of it could be other secondary minerals, but in general they are all poorly crystallized and thus do not lend themselves to visual ID. |
