ⓘ Anhydrite

Formula: CaSO₄

Habit: tabular

Colour: unknown

Description: Crystals formed early in the mineral paragenesis, then they all naturally dissolved away (as did the vast majority of it throughout the trap rock). Found as voids and molds in later minerals, some of these form epimorphs that show the full former anhydrite crystal habit.

ⓘ Epidote

Formula: (CaCa)(AlAlFe³⁺)O[Si₂O₇][SiO₄](OH)

Locality: O & G Woodbury Traprock Quarry (Orenaug Quarry; O & G No. 1 Quarry), Orenaug Hills, Woodbury, Litchfield County, Connecticut, USA

ⓘ Ferrosaponite ?

Formula: Ca_0.3(Fe²⁺,Mg,Fe³⁺)₃((Si,Al)₄O₁₀)(OH)₂ · 4H₂O

Locality: O & G Southbury Quarry (Silliman Quarry; O & G No. 2 Quarry), Orenaug Hills, Woodbury, Litchfield County, Connecticut, USA

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.

ⓘ 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".

ⓘ 'Pumpellyite Group'

Formula: Ca₂XZ₂[Si₂O₆(OH)][SiO₄](OH)₂A

Localities:

Habit: microfibrous, botryoidal, bowtie aggergates

Colour: dark olive green, blue-green, black

Description: The group includes pumpellyite series and julgoldite series. The former usually lines cavities while that latter may form late on top of other minerals. Few specimens are differentiated by analyses, however.

✪ Pumpellyite-(Mg)

Formula: Ca₂MgAl₂(Si₂O₇)(SiO₄)(OH)₂ · H₂O

Locality: O & G Southbury Quarry (Silliman Quarry; O & G No. 2 Quarry), Orenaug Hills, Woodbury, Litchfield County, Connecticut, USA

Habit: fibrous micro-crystals

Colour: dark olive green

Description: Based on the chemical formula given in Garabedian (1998), the species is pumpellyite-(Mg). Few specimens have been confirmed by analyses to differentiate it from several other possible pumpellyite group minerals. One of the first minerals to crystallize in vesicles, so is typically present between later minerals and the basalt matrix, a second stage crystallization came after early calcite, anhydrite, chalcedony, a trapezohedral zeolite, and datolite and so may coat or replace these minerals. May by itself fill entire vesicles.
