Formula: {A12+REE3+}{M3+2M32+}(Si2O7)(SiO4)O(OH)
Localities: Reported from at least 6 localities in this region.
Alluaudite ?
Formula: (Na,Ca)Mn2+(Fe3+,Mn2+,Fe2+,Mg)2(PO4)3
Habit: pseudomorph after triphylite?
Description: From Januzzi (1994): "Alluaudite, collected and recently identified by the author as occurring at Branchville (confirmation by Kampf, Los Angeles County Museum of Natural History), is evidently a pseudomorph after euhedral crystals of triphylite." Needs confirmation.
Reference: Januzzi, Ronald. E. (1994): Mineral Data Book - Western Connecticut and Environs. Mineralogical Press, Danbury, Connecticut.
Almandine
Formula: Fe2+3Al2(SiO4)3
Localities: Reported from at least 18 localities in this region.
Amblygonite
Formula: LiAl(PO4)F
Description: Penfield's 1879 analysis of a Branchville specimen showed an OH:F ratio of 1.02, making this specimen montebrasite as now defined. Many references are not specific to species, back then all of the massive lithium phosphate of this series was generically called "amblygonite". It is now known that the amblygonite species is incredibly uncommon even in localities which have fluorite, massive fluorapatite, and topaz. Therefore, specimens from this locality are most likely montebrasite.

Atacamite
Formula: Cu2(OH)3Cl
Habit: micro radiating clusters, aggregates, druses
Colour: deep green, sky blue
Description: Henderson (1967) reports: deep green crystals of quite variable habit up to 0.5 mm in size. The terminal planes of single crystals were generally bright, while faces in the prism zone were rounded and striated (Fig. 3). It also occurred as radiating groups and in irregular aggregates, sometimes with a single larger crystal perched on top. Druses of atacamite on vesicles were common. It was most frequently found close to or on cuprite, but occasionally appeared to be on malachite. Identification was based on its solubility in dilute hydrochloric and nitric acids, a positive test for halogen, and negative tests for carbonate and sulfate. The atacamite showed parallel extinction and weak birefringence, the two together ruling our malachite, antlerite and brochantite. The mineral was distinguished from paratacamite by its crystal form. On occasion, crystals corresponding to atacamite were found but with a sky blue color. These may well be pseudomorphs of rosasite after atacamite.

Description: This is all the information provided by Hoadley on the purported cronstedtite: "On a recent trip of the New York Mineralogical Club, under the guidance of the writer, to the Hubbard tungsten mine at Long Hill (Trumbull Township), Connecticut, Mr. George E. Ashby found a specimen of a chlorite, determined by Mr. Lazard Cahn as cronstedtite, 4FeO.2Fe2O3.3SiO2.4H2O. The specimen shows a group of black crystals 1/8 inch in diameter with perfect basal cleavage, hardness = 3.5, and rhombohedral hemimorphic, with the forms c (0001) and x (bar2021). This is believed to be the first occurrence of the mineral in the United States..." Identity questioned by Manchester (1931), p. 38. Description sounds like the common clinochlore found here.

Fairfieldite (TL)
Formula: Ca2Mn2+(PO4)2 · 2H2O
Type Locality:
Habit: foliated to lamellar masses, radiating masses consisting of curved foliated or fibrous aggregations
Colour: white to pale straw-yellow
Description: One variety cccurs filling cavities in the reddingite, and covering the distinct crystals of this mineral. It is uniformly clear and transparent, and is highly lustrous, showing entire absence of even incipient alteration. It is generally foliated to lamellar, although sometimes of a somewhat radiated structure. A second variety occurs in masses of considerable size interpenetrated rather irregularly with quartz, and quite uniformly run through with thin seams and lines of a black manganesian mineral of not very clearly defined character. Typically friable to the touch and lacks something of the brilliant luster of the first variety, it also shows greater difference of structure, passing from the distinct crystals to the massive and radiated form. Also occurs in small particles in fillowite and in masses of some size immediately associated with eosphorite, triploidite, and dickinsonite.

Habit: massive and columnar or blocky subhedral
Colour: white
Description: Penfield's 1879 analysis of a Branchville specimen showed an OH:F ratio of 1.02, making this specimen montebrasite as now defined. Many references are not specific to species, back then all of the massive lithium phosphate of this series was generically called "amblygonite". It is now known that the amblygonite species is incredibly uncommon even in localities which have fluorite, massive fluorapatite, and topaz. Therefore, specimens from this locality are most likely montebrasite.

Nantokite
Formula: CuCl
Habit: micro tetrahedra, etched to skeletal or in parallel groups
Colour: colorless to white
Description: Henderson (1967) reports: colorless translucent to white opaque 0.5 mm tetrahedra with and on cuprite and atacamite. Some of the crystals showed triangular etch pits on the tetrahedron faces (Fig. 1) and many were skeletal (Fig. 2) or occurred in parallel growth. Identification was made as follows. Very few white tetrahedral minerals are known, and of these, only nantokite CuCl and marshite CuI were likely to form from copper in the presence of sea water. Both these minerals are optically isotropic, and the above material was found to be so. In addition, the index of refraction was found to be about 1.93. Nantokite has an index of 1.930 while marshite has an index of 2.346. As a matter of fact, the index of refraction is alone sufficient to identify this mineral as nantokite since only a handful of minerals have indices as high as 1.9, and the above are the only tetrahedral minerals in the group. Many of the nantokite crystals were altered in part or entirely to a lime green mineral, and a few to a sulfur yellow material. It is interesting to note that nantokite has been reported to alter in air to the green mineral paratacamite.

Natrolite

Natrophilite (TL)
Formula: NaMn2+PO4
Type Locality:
Habit: massive, local alterations within lithiophilite
Colour: deep, wine-yellow
Description: Small regions within lithiophilite nodules. Description of type material from Brush and Dana (1890): "The luster is brilliant resinous to nearly adamantine; it was, in fact, the brilliancy of the luster which first attracted our attention, and which is, so far as the eye is concerned, its most distinguishing character. The mineral itself is perfectly clear and transparent, but the masses are much fractured and rifted. The surfaces are often covered by a very thin scale of an undetermined mineral, having a fine fibrous form, a delicate yellowish color and silky luster. This same mineral penetrates the masses wherever there is a fracture surface of cleavage or otherwise. What the exact nature of this mineral is we are unable to say, since the amount is too small to admit of a satisfactory determination - it appears to be a manganesian phosphate. It is evidently an alteration-product and would seem to imply that natrophilite is rather subject to easy chemical change. In any case this silky film is one of the characteristic features of the mineral, and directs attention to it at once even over the surface of a hand specimen where it is associated with lithiophilite and perhaps three or four other of these phosphates."

Type Locality:
Habit: bipyramidal, pseudo-octahedral - in tiny pockets in massive material
Colour: pale rose-pink to yellowish-white, sometimes brown
Description: From the type material description in Brush and Dana (1878): "Reddingite occurs sparingly in minute octahedral crystals; belonging to the orthorhombic system. It is also found more generally massive with granular structure; it is associated with dickinsonite, and sometimes with triploidite. As compared with the other species which have been described it is a decidedly rare mineral. The massive mineral shows a distinct cleavage in one plane...crystals are occasionally coated dark from surface alteration" Difficult to distinguish from pink hureaulite or yellowish fillowite.

Reference: Comstock (1880): Analyses of some American Tantalates
Tellurium
Formula: Te
Description: A careful reading of Silliman (1819a, 1819b, 1819c) indicates the tellurium was not native but chemically extracted from ferberite, which was also not from Monroe, but from the unique ferberite after scheelite deposit in Trumbull also worked by Ephraim Lane. Their origin was cleared up by Hitchcock and Silliman (1826). Januzzi misreads Silliman and mentions "tellurides" in his publications. Because the ferberite crystals from Lane's Mine of Trumbull have the shape of scheelite crystals (they are pseudomorphs with which he had no experience and was quite perplexed by) he thought he had a new mineral with tellurium in it. Silliman never mentions tellurides and his extraction of tellurium from ferberite has never been replicated.

Tungstenite ?
Formula: WS2
Tungstite (TL)
Formula: WO3 · H2O
Description: Original descriptions by Silliman (1822) and Bowen (1822) indicate the type material was found intimately associated with both unaltered scheelite and pseudomorphs of ferberite after scheelite unique to Lane\'s Mine of Trumbull, also worked at the time by Ephraim Lane. Samples were sold and shipped to Silliman, he did not collect them. Origin of the ferberite and scheelite was eventually cleared up by Hitchcock and Silliman (1826). The type locality should be changed to Lane\'s Mine of Trumbull.
