Triphylite from
State Forest Quarry #2 (State Forest No. 2 Mica Mine), Cobalt, East Hampton (Chatham), Middlesex Co., Connecticut, USA

Comments:"The first triphylite actually seen in Connecticut was discovered by the author at the State Forest Mine in East Hampton, around 1955. It was first noticed in the dump; a search of the locality soon revealed two small bodies of triphylite in the left hand wall of the open pit, just above the short tunnel. A number of specimens were collected, some being cleavage masses up to four inches wide. Siderite, messelite, ludlamite, and several other typical minerals were intergrown, most of them owing their origin to the hydrothermal alteration of the triphylite. One small crystal was noted." (Schooner 1961)
Habit:anhedral cleavable masses
Colour:pale gray-green
Abundance at site:Very Rare
