| ⓘ Clinozoisite Formula: (CaCa)(AlAlAl)O[Si2O7][SiO4](OH) Localities: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Corporate Drive, Long Hill, Trumbull, Fairfield County, Connecticut, USA State Route 111 construction site, Long Hill, Trumbull, Fairfield County, Connecticut, USA Old Mine Plaza construction site, Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: acicular to massive Colour: gray to gray-brown, brownish-green Description: The "epidote" and "zoisite" reported by Gurlt, Hobbs, Shannon, Schairer and Sullivan in the amphibolite is actually clinozoisite. It is abundant in the altered amphibolite and at the quartz-rich contact with the marble associated with the scheelite and ferberite. Non-terminated acicular crystals typically found in small vugs where calcite dissolved out. Shannon's (1921b) wet chemical analyses and RI values fall into the clinozoisite range, even though he called the mineral epidote. Otherwsie he described them thus: "columnar ash gray to brownish gray or nearly white mineral in prismatic crystals imbedded in glassy quartz. There is a small amount of green hornblende in the quartz and patches of calcite occur as the last deposit in cavities. By dissolving out the calcite, clear brown to gray crystals of the prismatic mineral are obtained." (Shannon, 1921b). |
| ⓘ Cobaltite Formula: CoAsS Description: Microcrystals. |
| ⓘ Copper Formula: Cu Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: thin lenses, masses, arborescent Colour: copper Description: From Januzzi (1994): "Native copper was originally found by the author at the upper working of the old tungsten mine where it occurs in exceedingly thin lenses and masses, at times distinctly arborescent in habit. Further research indicates that a series of copper minerals occur, in small amounts, as a component of the tailings, these species include: native copper, malachite, cuprite, chalcopyrite, bornite, chalcocite(?), and covellite(?). The latter two species have been reported but not confirmed. Native copper has been observed as inclusions in massive, iron stained, quartz. The most interesting occurrence takes the form of dendritic overgrowths on crystal faces of wolframite pseudomorphs after scheelite. This native element has also been observed in a matrix containing quartz, clinozoisite, pyrrhotite, and limonite." A photo is included in this reference. |
| ⓘ Cronstedtite ? Formula: Fe2+2Fe3+((Si,Fe3+)2O5)(OH)4 Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: rhombohedral hemimorphic, with the forms c (0001) and x (bar2021) Colour: black 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. |
| ⓘ Cuprite Formula: Cu2O |
| ⓘ Devilline Formula: CaCu4(SO4)2(OH)6 · 3H2O |
| ⓘ Diaspore Formula: AlO(OH) Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: thin or 6-sided tables flattened parallel to the shorter diagonal Colour: yellowish-white Description: First reported by Shepard (1842) as euclase forming "thin, transparent, yellowish-white tabular crystals, lining cavities in a silvery white mica, and sometimes imbedded in a dark purple fluor" in the topaz veins. Later retracted and confirmed to be diaspore by Shepard (1851) and Dana (1851): H=7-7.5, SG=3.29, alumina 84.9%, water 15.1% and described as "thin or 6-sided tables flattened parallel to the shorter diagonal". May be more common than reported because who has really looked? |

| ⓘ Epsomite ? Formula: MgSO4 · 7H2O |
| ⓘ Erythrite Formula: Co3(AsO4)2 · 8H2O Habit: secondary microcrystals Colour: pink Description: Secondary microcrystals associated with cobaltite microcrystals in cross-cutting calcite veins. |
| ⓘ Formula: BeAl(SiO4)(OH) Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA - erroneously reported Description: First reported by Shepard (1842), later retracted and confirmed to be diaspore by Shepard (1851) and Dana (1851). |
| ⓘ Ferberite Formula: FeWO4 Localities: Habit: pseudomorphs after bipyramidal scheelite Colour: black to dark brown Description: The only US locality for ferberite after scheelite crystals, with only about 8 other world-wide localities. First described by Silliman (1819-1822) but not recognized as pseudomorphic after scheelite for a few decades. Pseudomorph occurrence is locally restricted to the quartz/clinzoisite-rich contact between the amphibolite and marble at the upper mine pit, sometimes in small open spaces formed from the dissolution of calcite in that zone, and perhaps a nearby locality northeast of the "Burnett place" by Hobbs (1901). Occurs as anhedral lumps to euhedral crystals <1 to >10 cm, the latter size usually aggregates, in the amphibolite. Intermixed scheelite/ferberite partial replacement crystals are common. Some crystals reported with "spongy" texture, probably where tungstite formed and was weathered out. Typically called "wolframite" in most reports but Silliman's original wet chemical analysis shows it is what we now call ferberite and the use of the obsolete term "wolframite" should be abandoned. Januzzi (1994) confirms Silliman's Fe-dominant analysis: "Chemical analysis (Grand Junction Laboratory, Grand Junction, Colorado - Bauer) gave the following results: Tungsten 60.1%, Iron 17.8%, Manganese 0.21%.
Non-fibrous material yielded 16.3% iron and 0.95% manganese." References: |

| ⓘ Fluorite Formula: CaF2 Localities: Reported from at least 8 localities in this region. Habit: octahedral, cubic, dodecahedral, tetrahexahedral Colour: colorless, pale to emerald green, dark purple to light purple (violet) Fluorescence: purple Description: Excellent octahedral crystals transparent to translucent, in faults and veins, usually in groups, associated with calcite. Crystals can reach 5.8 cm on an edge. Also excellent purple cubic crystals to 2.5 cm. Rarely found as dodecahedrons, although dodecahedral faces are commonly found on some octahedral and cubic crystals. Very rarely found as tetrahexahedrons. References: |
| ⓘ Fluorite var. Chlorophane Formula: CaF2 Localities: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Corporate Drive, Long Hill, Trumbull, Fairfield County, Connecticut, USA Old Mine Plaza construction site, Long Hill, Trumbull, Fairfield County, Connecticut, USA State Route 111 construction site, Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: cleavable masses Colour: purplish-red to red-brown, salmon, colorless to grey, pale green, blue Fluorescence: Fluoresces blue-green under SW UV, with purer emerald green phosphorescence. Purple fluorescence under LW UV. Also thermoluminescent with emerald green color, but this will destroy any further fluorescence or thermoluminescence once cooled. Description: In cleavable masses up to 15 cm or more in the topaz-rich and albite-rich veins. Daylight color may fade to colorless on exposure to light with loss of fluorescence, though colorless material may still fluoresce. Keep this material in light-proof containers or wrapped in foil.

| ⓘ Galena var. Silver-bearing Galena Formula: PbS with Ag Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Description: Included in a list by Januzzi with no details, apparently based on early reports by Silliman of minerals actually from Lane's mine of Monroe. No modern data regarding the Ag content of galena from Connecticut has been published. |
| ⓘ Goethite Formula: α-Fe3+O(OH) Localities: Habit: botryoidal, fibrous Colour: brown Description: Botryoidal masses in open spaces of fluorite-calcite-albite-clinochlore-gypsum veins, apparently due to altered iron sulfides. |
| ⓘ Gold ? Formula: Au Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Description: Included in a list by Januzzi with no details. |
| ⓘ Graphite Formula: C Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: massive Colour: dark gray Description: A 6.5 x 5 x 3.5 cm specimen in Ronald Januzzi's collection contains a thin irregular layer of graphite frozen in massive quartz. Slight vugginess and rounded crude quartz crystals suggests the piece came from the vuggy quartz zone on the east corner of the upper mine pit. |
| ⓘ Greenockite ? Formula: CdS Habit: crusts and films on schist, free standing micro crystals on quartz and sphalerite Colour: yellow Description: yellow encrustations in the veins with galena, quartz, sphalerite, fluorite commonly labeled greenockite are not confirmed. SEM-EDS on one came back as “Probably a mixture of Fe, Mn, and Zn oxides/hydroxides and/or carbonates. Maybe goethite, hydrozincite, and a Mn mineral(s)? Definitely not greenockite or and any other sulfide. We checked another spot and got similar results, except no Mn.” Perhaps impure smithsonite. |

| ⓘ Topaz Formula: Al2(SiO4)(F,OH)2 Localities: Reported from at least 7 localities in this region. Habit: prismatic with square to rhombic section Colour: colorless, white, grey, green, yellow-brown, blue Description: A common, but locally variable component of the cross-cutting veins with quartz, fluorite, and muscovite, the latter commonly coating the crystals, even replacing them. Rarely gemmy. Crystals usually anhedral to subhedral prisms rarely terminated, up to 6 to 8 inches in diameter, with a length of 3 to 7 inches; micro crystals can be found that are transparent and show a great perfection of form and beauty. "Topaz is present in the quartz veins in quite unusual amount. The best locality is that described as the Limekiln Vein. This vein, which has been opened for a distance of some 75 feet, is from 1 to 5 feet wide. The vein originally consisted almost entirely of quartz and topaz, the quartz being considerably more abundant than the topaz...The topaz occurs in coarse crystalline masses of gray to pale yellow or white color, with well-defined cleavage, some of the cleavage surfaces being a foot in diameter. Most of the topaz contains veins and disseminated scales of margarodite, and large masses of margarodite contain cores of corroded and embayed topaz. Where the topaz abuts against small open cavities in the center of the vein it is bounded by rough crystal planes. Many of these cavities have been filled with coarse foliated margarodite not derived from the adjacent topaz crystals, as the surfaces of these crystals corroded." (Shannon, 1921b) |

| ⓘ Tungstenite ? Formula: WS2 Localities: Colour: Dark-Metallic Description: Very rare microcrystals possibly of this mineral occasionally found in marble. Analyses needed.
This ID is very doubtful given that the only report of tungstenite (a rare alteration of scheelite or ferberite) from the adjacent Old Mine Park by Schairer (1931) (a summary of other information) is almost certainly a misspelling of tungstite. The scheelite (or ferberite) is restricted to the amphibolite and does not occur in the marble. These could be primary ferberite micro-crystals (see photos). References: |
| ⓘ Tungstite (TL) Formula: WO3 · H2O Localities: Type Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: massive Colour: orange-yellow, chrome yellow, yellowish gray Description: An alteration of ferberite pseudomorphs after sheelite, coating and occupying cavities in these crystals from the upper mine pit. Looks like "broken sulfur". Very little of this material has been found since the mid-19th century as the highly weathered portion of the outcrop worked then by Charles Lane has long been removed by subsequent mining. Originally and incorrectly attributed to Lane's mine in Monroe, neither ferberite pseudomorphs after scheelite, nor scheelite occur there and so the type locality for this mineral is actually here. |
| ⓘ Uraninite Formula: UO2 Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: cubo-octahedral Colour: black Description: Januzzi (1994): "This micro-uraninite crystal (B14) was found embedded in dark purple fluorite occurring in the country rock zone (pegmatite) at the upper working of the old tungsten mine at Trumbull." Photos included in the reference. |
| ✪ 'Wolframite Group' Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA Habit: bipyramidal pseudomorphs after scheelite Colour: dark brown to black Description: Actually long known to be the iron-rich end-member species ferberite. The use of the term "wolframite" for crystals from here should be abandoned. See more description under ferberite. |

| ⓘ Zircon Formula: Zr(SiO4) |
| ⓘ Formula: (CaCa)(AlAlAl)O[Si2O7][SiO4](OH) Locality: Old Mine Park (Old Tungsten Mine), Long Hill, Trumbull, Fairfield County, Connecticut, USA - erroneously reported Description: The "epidote" and "zoisite" in the amphibolite and its quartz-rich contact with the marble mentioned in many reports is actually clinozoisite. |
