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.

Formula: Na(AlSi3O8)
Albite var: Oligoclase
Formula: (Na,Ca)[Al(Si,Al)Si2O8]
Description: The references provide no details, but a major component of area metamorphic rocks.
Reference: Schooner, Richard. (1958): The Mineralogy of the Portland-East Hampton-Middletown-Haddam Area in Connecticut (With a few notes on Glastonbury and Marlborough).
'Albite-Anorthite Series'
Habit: anhedral
Colour: white to greenish
Description: associated with allanite, fluorite, bastnaesite, pyrite, chalcopyrite in the pegmatite, species undetermined. Commonly stained brown from the decomposition of the sulfides.
Reference: Schooner, Richard. (1958): The Mineralogy of the Portland-East Hampton-Middletown-Haddam Area in Connecticut (With a few notes on Glastonbury and Marlborough).
Allanite-(Ce)
Formula: {CaCe}{Al2Fe2+}(Si2O7)(SiO4)O(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).

Nickelskutterudite
Formula: (Ni,Co,Fe)As3
Habit: grains
Description: "Shepard [1837] initially identified the Co-Ni bearing arsenide as the cubic di-arsenide, smaltite but after obtaining and studying additional material from his own mine he pronounced it to be a new orthorhombic tri-arsenide for which he proposed the name "Chathamite"....In the mid 1850s Genth (in Goodrich, 1854) questioned Shepard's identification and suggested that Chathamite was simply an iron rich variety of the cubic arsenide chloanthite (a misconception that perpetuated up to, and including, the 7th edition of Dana's Manual of Mineralogy). As it turns out, Shepard's Chathamite is indeed orthorhombic, but today would be classified as a nickel-cobalt rich loellingite." Gray (2005)

Formula: (Li,Na)2(Sr,Ca)Al4(PO4)4(OH)4
Colour: colorless
Description: "A colorless acicular mineral, found by the author in a vug of messelite, at the State Forest Mine in East Hampton, does not fit the description of any typical species except palermoite. Unfortunately, very little was obtained; an excellent sample was sent away for testing, but was evidently lost" (Schooner 1961). Most likely, this was a very poor guess.

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.
