The bedrock geology of East Haven is dominated by arkosic sandstone of the New Haven arkose, intruded by diabase of the Fair Haven dike swarm, and basalt of the Talcott lava flow. A heavily-developed town, there were numerous small trap rock quarries (most notably the now developed Cinque Quarry) and road cuts that exposed the diabase and basalt, which host essentially all the minerals listed below.
Coordinates are for the Town Hall.

Detailed Mineral List:
| ⓘ Albite Formula: Na(AlSi3O8) |
| ⓘ Analcime Formula: Na(AlSi2O6) · H2O |
| ⓘ Anhydrite Formula: CaSO4 Localities: Habit: tabular Colour: colorless to light blue Description: Crystals in voids in brecciated basalt with calcite, quartz, goethite, hematite. Confirmed via blowpipe flame test, which yielded bright orange Ca flame, not red, which would indicate Sr (celestine). References: |
| ⓘ Aragonite Formula: CaCO3 Localities: References: |
| ⓘ Baryte Formula: BaSO4 Localities: References: |
| ⓘ Bornite Formula: Cu5FeS4 |
| ⓘ Calcite Formula: CaCO3 Localities: Cinque Quarry, East Haven, New Haven County, Connecticut, USA High Street and Interstate 95 interchange, East Haven, New Haven County, Connecticut, USA McLay Avenue, East Haven, New Haven County, Connecticut, USA Foxon quarry, Foxon, East Haven, New Haven County, Connecticut, USA Farm River Rock Quarry, East Haven, New Haven County, Connecticut, USA Habit: scalenohedral Colour: white Description: Crystals to 3 cm, though typically around 1 cm. |
| ⓘ Chalcopyrite Formula: CuFeS2 Habit: anhedral Colour: brassy with iridescence Description: tiny irregular grains |
| ⓘ 'Chlorite Group' Localities: References: |
| ⓘ Chrysocolla Formula: Cu2-xAlx(H2-xSi2O5)(OH)4 · nH2O, x < 1 |
| ⓘ Dolomite Formula: CaMg(CO3)2 Localities: Habit: aggregate of curved rhombohedral crystals Colour: tan Description: 3mm aggregate on one specimen with calcite, quartz, goethite, hematite. References: |
| ⓘ Dolomite var. Iron-bearing Dolomite Formula: Ca(Mg,Fe)(CO3)2 |
| ⓘ Fluorapophyllite-(K) Formula: KCa4(Si8O20)(F,OH) · 8H2O Habit: tabular Colour: colorless Description: clear, late-forming crystals to 1 cm in voids in basalt with calcite and quartz. |
| ⓘ Goethite Formula: α-Fe3+O(OH) Localities: Cinque Quarry, East Haven, New Haven County, Connecticut, USA McLay Avenue, East Haven, New Haven County, Connecticut, USA Foxon quarry, Foxon, East Haven, New Haven County, Connecticut, USA Farm River Rock Quarry, East Haven, New Haven County, Connecticut, USA High Street and Interstate 95 interchange, East Haven, New Haven County, Connecticut, USA Habit: fibrous, acicular microcrystals, singly or in fan-shaped or bow tie aggregates Colour: brown to golden yellow Description: Needle-like and very small (micro) in size. It has a multi-colored tarnish which causes some specimens to be dark brown at the base, tapering off to a golden color at the end. Many of the aggregates appear as miniature "pincushions" which are generally dark brown. When many tufts occur together, they take on a velvety appearance which is quite beautiful. Another attractive aggregate occurrence are the goethite "bowties" which can frequently be found. Goethite is always found associated with quartz and calcite, and can be found as inclusions in quartz, which occurred during the final stages of crystal development. |
| ⓘ Gypsum ? Formula: CaSO4 · 2H2O Habit: powder Colour: white to pink Description: Powdery alteration of anhydrite, unconfirmed. |
| ⓘ Hematite Formula: Fe2O3 Localities: Habit: microscopic tabular plates and rosettes or botryoidal Colour: maroon to black Description: Black, platy rosettes ranging in size from super-micro to a more easily-seen three millimeters. As an inclusion in quartz, in which case it accounts for the bright red color of the host crystal. It also can be frequently observed as an inclusion in calcite. The red staining of any mineral found where can be attributed to hematite. |
| ⓘ 'K Feldspar' |
| ⓘ 'K Feldspar var. Adularia' Formula: KAlSi3O8 Habit: botryoidal aggregates Colour: creamy Description: mm-scale aggregates in voids in basalt with quartz, calcite, hematite, goethite. |
| ⓘ Malachite Formula: Cu2(CO3)(OH)2 Localities: References: |
| ⓘ Marcasite Formula: FeS2 Habit: radiating Description: a thin radiating structure, much like a pyrite sun, along a crack in the basalt |
| ⓘ Prehnite Formula: Ca2Al2Si3O10(OH)2 Localities: |
| ⓘ 'Pumpellyite Subgroup' Formula: Ca2XAl2[Si2O6(OH)][SiO4](OH)2A |
| ⓘ Pyrite Formula: FeS2 Localities: Habit: microscopic pyritohedrons and cubes Description: Typically perched on calcite or goethite, rather than quartz. Crystals include "right angle" crystals. |
| ⓘ Quartz Formula: SiO2 Localities: Reported from at least 6 localities in this region. Habit: very short prismatic or quartzoid, commonly doubly-terminated Colour: colorless to white Description: Crystals to 1 cm, commonly colored green or red by chlorite or hematite inclusions.
