Tariffville Gorge was cut through the Talcott and Holyoke Basalts by the Farmington River just east of the village of Tariffville in Simsbury. The Holyoke Basalt ridge south of the river is the boundary for Simsbury to the west and Bloomfield to the east. East Granby is across the river to the northeast.
The mineral localities generally referred to as from "Tariffville" or "Tariffville Gorge" are on the south side of the river in Bloomfield. They consist of a small, old trap rock quarry situated on the nose of the basalt ridge where it dives down to the river from the south (near the north end of Tariffville Road) and a road cut in the basalt on state Route 189 just SE of the old quarry. Route 189 passes through the gorge on the south side of the river. Both localities have at different times (before the 1930s and in the late 1950s, respectively) produced minerals from the basalt.

Detailed Mineral List:
| β Analcime Formula: Na(AlSi2O6) · H2O Habit: trapezohedral Description: A single crystal 2.5 cm pseudomorphed by talc, in datolite, calcite, prehnite. References: |
| β Anhydrite Formula: CaSO4 Localities: Habit: cleavable masses Colour: pale blue Description: "...light blue, glassy, and completely unaltered, in masses up to two or three inches across. It was intimately associated with pectolite and thaumasite..." Schooner (1961) |
| β Calcite Formula: CaCO3 Localities: References: |
| β Datolite Formula: CaB(SiO4)(OH) Localities: Habit: complex equant Colour: colorless to very pale yellow-green Description: "...outstanding specimens of small glassy crystals, of two different habits, intimately associated, coated with gilt-like stilpnomelane." Schooner (1961) |
| β Fluorite Formula: CaF2 Locality: State Route 189 road cut, Tariffville Gorge, Bloomfield, Hartford County, Connecticut, USA Description: Mentioned rather ambiguously by Schooner (1961) as "evidently existed in trap-rock at a rather recent road cut in Tariffville... a rare association", with no further details. |
| β Pectolite Formula: NaCa2Si3O8(OH) Localities: Habit: spherical aggregates of radiating acicular crystals Colour: white, light tan Description: "The author was given several fine specimens of radiating white pectolite, with anhydrite and thaumasite, from a road cut, in trap-rock, at Tariffville. The material was very clean, though it has since become tan, and, occurred in extremely hard and non-porous basalt." Schooner (1961). |
| β Prehnite Formula: Ca2Al2Si3O10(OH)2 References: |
| β Quartz Formula: SiO2 Localities: References: |
| β Stilpnomelane Formula: (K,Ca,Na)(Fe,Mg,Al)8(Si,Al)12(O,OH)36 · nH2O Locality: State Route 189 road cut, Tariffville Gorge, Bloomfield, Hartford County, Connecticut, USA Description: "gilt-like" and encrusting quartz, calcite, datolite, and other species, according to Schooner (1961) |
| β Talc Formula: Mg3Si4O10(OH)2 Habit: trapezohedral (pseudomorph) Colour: dark greenish-black Description: Soft, dark blackish-green mineral pseudomorphing what apparently was an analcime crystal, in datolite, calcite, prehnite. References: |
| β Thaumasite Formula: Ca3(SO4)[Si(OH)6](CO3) · 12H2O Localities: |
