European settlers arrived in 1739 from Eastham, Massachusetts. In 1746, they named their community Easthampton parish after their former home of Eastham. In 1767, the community was separated from Middletown and incorporated by the Connecticut General Assembly as the township of Chatham, after Chatham, Medway due to the important shipbuilding industries that both places had in common. The town name was officially changed to East Hampton in 1915.
East Hampton lies within the eastern-central part of the Middletown Pegmatite District and so contains hundreds of pegmatites and many prospects and quarries. Straddling the Bronson Hill island arc terrane and the Central Maine oceanic terrane, the geology consists of mostly metamorphic rocks - gneiss, schist, calc-silicate gneiss, and quartzite of volcanic, plutonic, and sedimentary origin. As a result, the topography is very rugged and parts of the town are heavily forested. The quartzite underlies Great Hill, near the village of Cobalt, where cobalt and nickel were mined along Mine Brook, and microscopic gold occurs in arsenopyrite veins.
Coordinates are for the center of town on state Route 196.

β Albite var. Cleavelandite Formula: Na(AlSi3O8) Localities: Anderson No. 1 Mica Mine (Swanson Mine; Swanson Lithia Mine; Old Lithia Mine; Chatham Lithia Mine), East Hampton (Chatham), Middlesex County, Connecticut, USA Enegren Mica Mine (Power Mica Mine), East Hampton (Chatham), Middlesex County, Connecticut, USA Slocum prospect, East Hampton (Chatham), Middlesex County, Connecticut, USA Habit: anhedral platy to tabular Colour: white to very pale blue Description: Abundant as large, pure aggregates with quartz in the intermediate zone and in the lepidolite-cleavelandite zone. In the intermediate zone the thin, platy crystals easily reach 15 cm or more and are tightly packed with little open space and are very rarely terminated. Generally as much smaller masses occur in the lepidolite-cleavelandite zone. |
β Albite var. Oligoclase Formula: (Na,Ca)[Al(Si,Al)Si2O8] Description: The references provide no details, but a major component of area metamorphic rocks. |
βͺ Allanite-(Ce) Formula: (CaCe)(AlAlFe2+)O[Si2O7][SiO4](OH) Habit: elongated prisms Colour: black, very dark brown Description: Very sharp terminated crystals crystals, up to half an inch in diameter and five or six inches in length, accompany pink fluorite. Massive material also occurs, intergrown with quartz, bastnaesite, pyrite, chalcopyrite, and white to greenish plagioclase (commonly stained brown). The allanite is not very radioactive and was identified by an x-ray diffraction test by Mary E. Mrose of the U. S. Geological Survey. She indicated that it gave an exceptionally clear pattern. It was obviously non-metamict, in keeping with its unaltered appearance and virtual lack of radioactivity. Note: Schooner misidentified these as staurolite in Zodac (1940). |
β Almandine Formula: Fe2+3Al2(SiO4)3 Localities: Reported from at least 17 localities in this region. Description: Not tested, but species probably almandine, as most schist-hosted garnets in Connecticut have proven to be. Crystals to 1-2 inches. |
βͺ 'Almandine-Spessartine Series' Locality: Great Hill Pond Brook pegmatite, Cobalt, East Hampton (Chatham), Middlesex County, Connecticut, USA Habit: trapezohedral Colour: dark maroon with black coating Description: Crystals to 4 inches. Referred to by Schooner as spessartine, but most likely impure almandine based on XRF analyses of many other district pegmatitic garnets. |
β Annabergite Formula: Ni3(AsO4)2 · 8H2O Locality: Great Hill cobalt mines, Cobalt, East Hampton (Chatham), Middlesex County, Connecticut, USA Habit: coatings Colour: bright to pale green Description: waxy, pale to bright green coatings on ore-bearing host rocks, particularly around bronze nickeline grains. |
β Annite Formula: KFe2+3(AlSi3O10)(OH)2 Localities: Reported from at least 11 localities in this region. Habit: subhedral Colour: black Description: Listed in references as biotite. Accessory in the wall zone. |
β Anorthite Formula: Ca(Al2Si2O8) Localities: Habit: anhedral grains Colour: greenish-gray Description: A component of the banded amphibolite of Shepard's Lode. |
β Anorthite var. Labradorite Formula: (Ca,Na)[Al(Al,Si)Si2O8] Description: The references provide no details, but anorthite is a component of the diabase dike exposed in the cut. |
β Arrojadite-(KFe) ? Formula: (KNa)(Fe2+◻)Ca(Na2◻)Fe2+13Al(PO4)11(PO3OH)(OH)2 Description: reported by Dick Schooner, no details in the reference. |

Associated with pyrrhotite locally altered to pyrite. Native gold, generally as micron sized grains, is found, along with pyrite and chalcopyrite, in a network of thin fractures and veins cutting the arsenopyrite. The arsenopyrite is not the Co-Ni ore, earlier references to and analyses of "danaite" are probably from confusion with the loellingite ore veins. References: |

β 'Lepidolite' Localities: Habit: granular, as globular radial aggregates Colour: gray to pink to purple Description: Abundant in the lepidolite-cleavelandite zone. Shannon (1920) gives best overall description - "Some masses are composed of bright small scales of a beautiful deep purple-pink color, intergrown with fine platy cleavelandite stained yellow brown by iron, the contrast in colors yielding very showy specimens. Other coarser scaly masses are pale lavender to gray in color and much of the material shows small spheres up to the size of a pea composed of folia of grayish lepidolite embedded in white cleavelandite."
Hess et al (1943) describe the lepidolite as "globular radial aggregates ranging from less than 1/4 inch to 3/4 inch in diameter". They analyzed the lepidolite for alkali metals and reported that a "visual estimate from the spectrographic pattern of the lepidolite gave K2O, 5.0; Na2O, 1.0; Li2O, 5.0; Rb2O, 3.0; Cs2O, 1.0" percent. |

Schooner (1958) states: "In December of [1953], on a most fortunate visit to the active Worth Quarry on Hog Hill in East Hampton, a couple of miles from the road cut locality, the author found a considerable amount of scheelite on the dump and even in the road. Trucks had been driving over one slab which must have weighed fifty or a hundred pounds! Several dozen very rich specimens, some of them pure masses up to three inches across and an inch thick, were collected. The color of this material was white or gray, and the fluorescence was vividly blueβ¦ though it was found during the day, without benefit of an ultra-violet light. The scheelite, with some greenish plagioclase and various sulfides, evidently came from quartz veins in the schist, adjacent to the pegmatite. The occurrence was not entirely erratic; in the summer of l954, W. P. Reid and the author obtained still more specimens. They showed broken crystals, up to two inches in diameter, in a matrix of quartz, grossularite, and either hornblende or actinolite. A few loose crystals, from one half to three quarters of an inch in diameter, were secured. Since that time, little if any scheelite has come out of the Worth Quarry... at least, to the authorβs knowledge."
Schooner (1961) provides a similar description: "The best locality is the active Worth Quarry on Hog Hill in East Hampton, where the mineral occurs in quartz veins adjacent to the pegmatite. On one occasion, in 1953, just after the author had become interested in the mineral, he collected perhaps a hundred pounds of scheelite specimens at this locality. Many loose pieces, up to a couple of inches across, were picked up on the dump; a large slab, about a foot square, consisted of virtually pure scheelite, between thin layers of biotite schist. A little pyrite and pyrrhotite accompanied the scheelite. On subsequent occasions, more examples were obtained⦠including several well developed crystals, half an inch in diameter. Among the later discoveries at the Worth Quarry, the scheelite has been in various matrices; they included actinolite and hornblende, with a gray plagioclase, probably labradorite, and a brownish grossularite. The scheelite is always highly fluorescent." |

β Triphylite Formula: LiFe2+PO4 Localities: State Forest Quarry No. 2 (State Forest #2 Mica Mine; Carini Quarry), Cobalt, East Hampton (Chatham), Middlesex County, Connecticut, USA 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."

β Triphylite var. Ferrisicklerite Formula: Li1-x(Fe3+xFe2+1-x)PO4 Description: sparingly with the triphylite |
β Triplite Formula: Mn2+2(PO4)F Habit: massive Colour: reddish to maroon Description: As irregular masses, commonly in bunches intergrown with blue elbaite and dark purple lepidolite and hosted by cleavelandite/elbaite/quartz. Tan alteration rind around the edges is probably hydroxylapatite (see below) and Schooner reports finding hureaulite. These minerals are characteristic of alteration from primary lithiophilite but none has ever been reported, so it is difficult to say if the triplite is primary. Masses of garnet may appear similar, but are harder and show a network of rhombic etch patterns on fracture surfaces. Descriptions from the literature are below:
Shannon (1920) - "bunches and masses up to several inches across of a flesh red to brownish red material resembling massive garnet, which upon analysis proves to be triplite...In places the triplite has oxidized to a black manganese oxide, which stains the cleavelandite."
Foye (1922) - "intimately intergrown with a dark blue, massive tourmaline".
Schooner (1958) β "Large masses, up to a foot square, occurred in a mixture of that mineral and cleavelandite. The author was fortunate in securing a large specimen of completely fresh material from a weathered boulder on the oldest dump. Most examples show what are probably crude crystals, bordered with blue tourmaline. Much of the triplite is altered to a cellular tan mineral which has not been thoroughly identified. One piece, evidently from deep in the pegmatite, has undergone a more complex alteration to a foliated dull green substanceβ¦negatively identified as not being dickinsonite. Such material could easily be confused with chloritized garnet. Indeed, the fresh triplite resembles massive garnet; its comparative softness and its cleavages should distinguish it. Mary E. Mrose x-rayed this triplite for the author and found it to give a characteristic pattern. E. V. Shannon, who originally described the occurrence in 1920, gave the following analysis: calcium oxide 3.18, magnesium oxide 0.58, iron oxide 4.95, manganese oxide 52.40, phosphorous oxide 32.81, fluorine 9.09, water 0.35, and remainder 1.17. The specific gravity of the sample was 3.58."
Schooner (1961) - "Reddish-brown cleavages, bordered with blue tourmaline, definitely identified as such, were apparently quite common in the original lepidolite pit, where that mineral, together with quartz and cleavelandite, occurred as coarse intergrowths. The author found a solid mass, over six inches across, in the old dump there; some of the triplite bodies must easily have been a foot in diameter. In many cases, the triplite is partially or completely altered to a granular yellow or tan mineral; x-ray study proves this to be apatite, of a surprisingly normal kind. This work was done by Peacor."
