Brace (1823) wrote about the minerals found in the "greenstone" (basalt) range in Southbury and listed some minerals that were repeated by Robinson (1825) - the ones typically resistant to weathering (jasper, chalcedony, agate, quartz, amethyst, prehnite) or caused by it (common opal or hyalite). Shepard (1837) added the delicate laumontite. At that time there were no active quarries, so the minerals were found in various outcroppings at unspecified places around town but are indicative of those found in quarries in the last several decades.

Other minor finds, mostly in boulders, were mentioned by Shepard (1837), such as chalcopyrite, arsenopyrite, and ilmenite. Silliman (1822) and Robinson (1825) also mention 90-degree twins of staurolite from an unspecified locality "3 1/2 m. S. W. from Smith's inn" (with pyrite in the same area), placing it in the metamorphic bedrock near the confluence of the Pomperaug and Housatonic Rivers. Robinson (1825) also notes rare beryl "2 m. S. from Smith's inn", putting this also in the metamorphic rocks of the Bullet Hill Road area.

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.

Fluorapatite
Formula: Ca5(PO4)3F
Reference: Ryerson, Kathleen H. (1972) Rockhouns Guide to Connecticut
Fluorapophyllite-(K)
Formula: KCa4(Si8O20)(F,OH) · 8H2O
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-(Mg)
Formula: Ca2MgAl2(Si2O7)(SiO4)(OH)2 · H2O
Habit: fibrous micro-crystals
Colour: dark olive green
Description: Based on the chemical formula given in Garabedian (1998), the species is pumpellyite-(Mg). 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.
