State Forest #2 Mica Mine; Carini Quarry
A granite pegmatite quarried and mined (there is a short flooded adit and drift on the NE wall) for mica during WWII. The only real description is given by Cameron et al (1954):
During the summer of 1942, it was worked by J. Carini, South Glastonbury, who recovered a few tons of mica. From February to August 1943, the mine was operated by F. and J. Burrone Bros., North Branford, and a small production of mica was maintained...[In May 1943] the only working was an opencut about 80 feet long, 10 to 20 feet wide and 10 to 20 feet deep, but the cut was largely backfilled.
The mine is in a tabular pegmatite enclosed in, and roughly concordant with, northward-dipping quartz-mica schist (Bolton schist). The body strikes N. 5° W. to N. 50° W. and has been traced for about 90 feet. The dip of the hanging wall ranges from 18° NE. to vertical, but in general is 40° to 45° NE. The footwall is uneven but is probably about parallel to the hanging wall. The pegmatite ends at the northwest end of the cut in a blunt nose that plunges steeply northward. Just southeast of the quarry rim, the pegmatite seems to plunge beneath schist, but this may be due to a roll in the wall similar to several found during mining.
The pegmatite shows border, wall, and intermediate zones and a discontinuous core. The border zone, 2 to 3 inches thick, consists of fine-grained quartz and muscovite, with accessory apatite and tourmaline. The wall zone consists of coarse plagioclase and quartz, with scattered muscovite books 2 to 10 inches broad and ¼ to 5 inches thick. Accessory minerals are biotite [annite], apatite, tourmaline, and garnet. The wall zone is 3.5 to 4 feet thick along the hanging wall where exposed. The corresponding part of the pegmatite along the footwall was not exposed.
The intermediate zone consists of coarse quartz, [microcline] perthite, and plagioclase with subordinate muscovite and accessory biotite [annite], apatite, tourmaline, and beryl. The zone encloses lenses of quartz with books of muscovite around their margins. The quartz lenses are probably segments of a discontinuous core, with a poorly defined discontinuous muscovite-bearing core-margin zone.

The quartz lenses are probably segments of a discontinuous core, with a poorly defined discontinuous muscovite-bearing core-margin zone.
The pegmatite has since become locally well known for a small triphylite mass that altered into a suite of secondary minerals very similar to those found at the Palermo Mines in North Groton, New Hampshire, USA. The triphylite was discovered by Dick Schooner around 1955 as "an irregular mass, approximately two feet across, in the left hand wall of the open pit, just above the tunnel" (Schooner 1958). The abundant gray microcline at this locality should not be confused with triphylite.

Distinct crystals, with a pearly luster, were noted in vugs of the massive mineral." Schooner (1961). Associated with triphylite, siderite, strunzite, laueite, mitridatite, ludlamite, vivianite.
A green mineral thought to be beraunite was tested by XRD (with some matrix) at the National Museum Prague (dr. Jiri Sejkora) and found to be "no beraunite but something similar to messelite". The green may be only a coating. References: |
| ⓘ Microcline Formula: K(AlSi3O8) Habit: anhedral Colour: white to gray Description: a component of the intermediate zone of the pegmatite. Gray color causes confusion with the very rarely found triphylite. |

Very few specimens have been found, and they are small; the crystals are green and quite glassy, the largest being about an eighth of an inch in diameter. The author suspected the identity of this material from the time he discovered it, several years ago, but it was not confirmed until recently. Some of the optical data follows: R. I. 1.615; optical angle 45 degrees, more or less; optic sign negative; birefringence high." (Schooner 1961) References: |

The identity of this material was confirmed by Clifford Frondel of Harvard University." (Schooner 1958) Associated with triphylite secondaries. References: |
| ⓘ Triphylite Formula: LiFe2+PO4 Habit: anhedral cleavable masses Colour: pale gray-green Description: "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."
