Wildcat Member [of Taine Mountain Formation]

Gray, medium-grained, generally fairly well layered to well-laminated ("pin-stripe") gneissic or schistose granofels, composed of quartz, oligoclase, biotite, muscovite, and garnet, and locally staurolite and kyanite or sillimanite. The Taine Mountain Formation of Stanley (1964) is here adopted in the Collinsville and Bristol quads., CT. Includes three pinstriped units, the Wildcat, Scranton Mountain, and Whigville Members of Stanley (1964), also adopted. Wildcat Member is the basal pinstriped gneiss unit of the Taine Mountain, which correlates with the Savoy Schist of Emerson (1898), Missisquoi Schist or Group of Richardson (1919, 1924) in MA; and the Moretown Formation of Cady (1956) in MA and VT. Inferred age is Middle Ordovician (Simpson, 1990).
