| β Axinite-(Fe) Formula: Ca2Fe2+Al2BSi4O15OH Habit: "small plates and confused aggregates" (Schooner, 1961) Colour: pale lavender-gray Description: Intergrown with albite, epidote, diopside, actinolite, clinozoisite, and titanite w/accessory rutile, apparently from a calc-silicate lens. Yale Peabody Museum has two similar specimens labeled as coming from a Route 8 road cut. Another specimen has a label saying it is from a roadcut north of Thomaston, perhaps the large cuts at the intersection of Routes 8 and 222. Schooner (1961) says the assemblage was "found in the area around the Thomaston Dam" and that "some excellent specimens" were obtained. Clear microcrystals are present in little voids between the massive axinite plates. |

| β Baryte Formula: BaSO4 Localities: Thomaston Dam railroad cut, Thomaston Dam, Thomaston, Litchfield County, Connecticut, USA Pfizer Company Marble Quarry (New England Lime Co. quarry; NELCO quarry; Specialty Minerals Inc.; Minerals Technologies Inc.; Canaan Limestone Quarry; Connecticut Lime Company; Canaan Lime Company; Lewis Quarry), Canaan, North Canaan, Litchfield County, Connecticut, USA O & G Woodbury Traprock Quarry (Orenaug Quarry; O & G No. 1 Quarry), Orenaug Hills, Woodbury, Litchfield County, Connecticut, USA Habit: tabular Colour: white Fluorescence: bright yellow, cream under SW UV Description: Mostly it is found massive, but it also occurs in crystals up to one-half inch or more. May be confused with calcite, which occurs here as very thin tabular white crystals that mimic barite. Vogt describes baryte as "thin, white tabular crystals from a quarter inch to two inches across. While some of the barite fluoresces a cream color under shortwave ultraviolet light, other appears to be a salmon-pink." The latter is color is typical of calcite fluorescence. However, Vogt also states: "A bright yellow fluorescence of barite was observed when small crystals of honey-colored calcite were in close proximity to the barite. Some unusual forms of pyrite can be found in between the barite platelets. The mineral occurs associated with calcite, fluorite, galena, pyrite, quartz, sphalerite". Use acid to differentiate baryte from tabular calcite here. |
| β Bementite ? Formula: Mn7Si6O15(OH)8 Localities: Description: Listed as associated with rhabdophane but no site-specific details given. |
| β Beraunite ? Formula: Fe3+6(PO4)4O(OH)4 · 6H2O Habit: stains and encrustations Colour: dark green Description: Very poorly crystallized in fracture fillings. |

A 300-pound block of quartz and plagioclase found in the backfill contains at least 8 percent beryl. Also an accessory of the pegmatites in the no. 2 quarry. Sterrett (1923) reports βmany crystals of beryl, some of them more than a foot in diameterβ. Crystals are usually sheathed in mica and are poorly formed but internally contain some of the best gem beryl rough found in Connecticut. |
| βͺ Beryl var. Aquamarine Formula: Be3Al2Si6O18 Habit: subhedral elongated prisms Colour: blue, blue-green Description: Much more rare than the common green beryl or yellow beryl, but a 40.44-carat aquamarine (no. 1037) is in the Smithsonian. |

| β 'Chlorite Group' Localities: Reported from at least 18 localities in this region. References: |
| βͺ 'Chlorophyllite' Habit: prismatic Colour: silvery gray-green Description: Micaceous alteration of cordierite, the latter crystals up to 8 cm across but typically fragmented into sections along a relict basal cleavage. May not be from this town specifically as the geology is not quite right, noted mainly from Haddam or eastern Litchfield - which is close to Thomaston, which was once part of Plymouth. |
| β Chondrodite Formula: Mg5(SiO4)2F2 Localities: References: |
| β Chrysocolla Formula: Cu2-xAlx(H2-xSi2O5)(OH)4 · nH2O, x < 1 Habit: encrustation Colour: blue-green Description: Coating chalcopyrite grains. |

In Januzzi (1994) the discoverer states, "Recent examination, by way of x-ray and semi-quantitative analysis uncovered a new species for the Scoville Ore Bed in Salisbury, Connecticut; the mineral churchite, a relatively inconspicuous species and confused (no doubt often) with rhabdophane and probably more common than realized. Florencite should be looked for when churchite occurs in a deposit of this type. A hyalite-like mineral evidently forming before churchite lies just beneath it (the specimen is in the authorβs collection)-this species is very possibly evansite." |
| β Clinochlore Formula: Mg5Al(AlSi3O10)(OH)8 Localities: Reported from at least 8 localities in this region. References: |

| β Diopside Formula: CaMgSi2O6 Localities: Reported from at least 18 localities in this region. Habit: flattened short to elongated prisms
Colour: white to very pale green Fluorescence: light blue-gray under SW Description: pseudomorphed by tremolite (originally called Canaanite) References: |
| β Dolomite Formula: CaMg(CO3)2 Localities: Reported from at least 6 localities in this region. |
| β Epidote Formula: (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH) Localities: Reported from at least 12 localities in this region. Description: Included in species lists without any supporting data, but it is very common in the state and plausible for the metamorphic geology of the area. |
| β Epistilbite ? Formula: CaAl2Si6O16 · 5H2O Description: According to Januzzi (1976) "Epistilbite has been collected and confirmed from the Route 8 locality in Watertown." However, there is no mention of it in Tschernich (1992), which does mention other Connecticut localities for this mineral. |
| β Erythrite ? Formula: Co3(AsO4)2 · 8H2O Description: Mentioned by Januzzi (1976) but he does not describe any primary sulfide it may have formed from. Likely confused with an alteration product of the triphylite. |
| β 'Fayalite-Forsterite Series' Localities: |

| β 'Feldspar Group var. Perthite' |
| β 'Fergusonite' ? |
| β 'Ferro-actinolite-Tremolite Series' |
| β Ferroberaunite Formula: Fe2+Fe3+5(PO4)4(OH)5 · 6H2O |
| β Ferrosaponite ? Formula: Ca0.3(Fe2+,Mg,Fe3+)3((Si,Al)4O10)(OH)2 · 4H2O Habit: micaceous or foliated globules or coatings Colour: very dark green to black Description: A late forming, fine-grained, very dark green to black micaceous mineral forming tiny globules or coating other minerals in vesicles in basalt. An SEM-EDS analysis conducted in 2017 concluded the mineral is an Fe-Mg-Ca aluminosilicate. The complete absence of K rules out stilpnomelane, biotite, celadonite. The Ca is too low for pumpellyite or julgoldite. A mindat.org mineral search by chemistry found ferrosaponite as a good match, as are its physical properties and geoenvironment of formation. However, XRD is needed for confirmation. |
| β Fluorapatite Formula: Ca5(PO4)3F Localities: Reported from at least 19 localities in this region. Description: Sharp blue crystals that were damaged upon discovery. Yellow fluorescence. References: |
| β Fluorapatite var. Manganese-bearing Fluorapatite Formula: (Ca,Mn2+)5(PO4)3(F,Cl,OH) or Ca5([P,Mn5+]O4)3(F,Cl,OH) Colour: Light bluish green Fluorescence: pinkish to orange Description: Light bluish green nodules with an occasional crystal. Fluoresces pinkish to orange under short wave. |
| β Fluorapophyllite-(K) Formula: KCa4(Si8O20)(F,OH) · 8H2O Localities: Habit: bipyramidal Colour: colorless to white Description: Crystals can reach 2-3 cm, though commonly 1 cm or less. The tips of the pyramids are typically physically degraded and milky, leading to the term "snow-cone" habit for these crystals. 2018 SEM-EDS analyses or three samples has confirmed the "-(K)" nature of these crystals, but not whether they are "fluor" or "hydroxy". |
| β Fluorite Formula: CaF2 Localities: Thomaston Dam railroad cut, Thomaston Dam, Thomaston, Litchfield County, Connecticut, USA O & G Woodbury Traprock Quarry (Orenaug Quarry; O & G No. 1 Quarry), Orenaug Hills, Woodbury, Litchfield County, Connecticut, USA Rockside Quarry (Mine Hill Quarry), Mine Hill (Ore Hill), Roxbury, Litchfield County, Connecticut, USA Reynolds Bridge, Thomaston, Litchfield County, Connecticut, USA Habit: cubic, sometimes modified by dodecahedron and tetrahexahedron Colour: purple and green shades to colorless, usually in layers Fluorescence: blue-white to purplish blue under SW UV, often zoned with the daylight color. Description: Very common in hydrothermal fault veins as coarse crystalline masses, found with most minerals present in these veins: quartz, calcite, galena, sphalerite, pyrite, zeolites, with open spaces lined by tightly packed, rough-surfaced (from many small sub-faces) crystals. Crystals to 7 cm were removed intact during the initial blasting of the railroad cut. As well-formed euhedral isolated crystals in voids with other minerals usually up to 2 cm. References: |

Colour: white Description: White crystals to about 1 cm, commonly dusted with micro-pyrites. This zeolite has the same morphology as phillipsite, but according to Tschernich's 1992 "Zeolites of the World", harmotome is typical of lead deposits whereas phillipsite occurs in volcanics. This locality is thus favorable for harmotome. Henderson (1979) analyzed crystals and found that "...microprobe analysis shows the Ba:Si ratio to be 1.2:6, and the amounts of K, Na and Ca to be low. This data fits harmotome perfectly, and is not consistent with either phillipsite or wellsite."

| β Ilmenite Formula: Fe2+TiO3 Localities: Reported from at least 11 localities in this region. Habit: platy to tabular Colour: black submetallic Description: Found in three modes: 1. As small (<1 cm) crystals scattered in schist, gneiss and amphibolite. 2. As deformed platy concentrations in quartz/albite/mica boudins in schist. Loose boudins as boulders vary in size from "turtle shell" pieces, to boulders pushing a meter across with overlapping, curved crystals or aggregates on the order of 10 cm.
3. As undeformed, tabular crystals exceeding 10-15 cm (mostly broken so hard to say exactly), 1 to 15 mm thick, that grew rooted in the chlorite-rich contact of schist with discordant quartz masses. These crystals typically oriented edge-on to the contact and surrounded by massive quartz that evidently filled in after they crystallized. Most of these "ilmenite" crystals are actually pseudomorphed by, to varying degrees, magnetite, hematite, rutile, chlorite, even within the same crystal. As ilmenite is weakly magnetic, it is easy to tell the strongly magnetic magnetite pseudos from ilmenite. The rutile/hematite pseudos are reddish and non-magnetic and blood-red, acicular microcrystals can be seen in them under a scope. References: |

Habit: pagoda-like polysynthetic twins on (111) resulting in pseudo-hexagonal "prisms" with re-entrant striae Colour: dark reddish-brown, dark brown, black Description: In hydrothermal fault veins associated with barite, calcite, fluorite, galena, pyrite, quartz, and zeolites. Pete Dunn analyzed crystals in 1973: βIt has been said that the wurtzite from Thomaston Dam, Connecticut, was of a type that changed to sphalerite under the crushing necessary for a powder x-ray photo. This thought intrigued me and I checked it out by taking a regular powder photo after crushing the sample in the usual fashion, and then took another x-ray using the Gandolfi camera which gives powder photos from single crystals. Result β both photos perfect sphalerite patterns, and identical" (Yedlin, 1973a). Henderson (1979) showed diagrams of sphalerite crystals epitaxial on supposed wurtzite, and the other way around, with a (0001) (pinacoidal) face of "wurtzite" matching a (111) (tetrahedral) face of sphalerite. In any case, the crystals from this locality, commonly labeled "wurtzite" appear to be polysynthetically twinning, combined positive and negative tetrahedra of sphalerite on a 6-sided (111) face. Note the re-entrant angles that circumscribe the "prisms" of these crystals, which are indicative of twinning. References: |
