A city first settled by Europeans in 1638 and incorporated as a city in 1784. It is the home of Yale University and the Yale-Peabody Museum, which houses a substantial world-wide mineral collection. Surrounding towns (such as East and West Haven and Hamden) were separated from New Haven over the centuries since its incorporation, leading to the inclusion of minerals in old or general references (like Robinson (1825), Schairer (1931), Sohon (1951), Januzzi (1976)), that are now attributable to these other towns or where just noted as "near" New Haven.
The bedrock geology of New Haven consists mostly of rocks within the Early Mesozoic Hartford Basin, part of the Newark Supergroup of rift basins. These rocks are mostly the Triassic New Haven Arkose with prominent ridges at West and East Rocks underlain by the Jurassic West Rock Diabase sill/dike complex. Other Jurassic dikes form smaller ridges along the east city border and cutting West Rock just north of the state Route 15 tunnel. Quarrying of diabase has produced prehnite, calcite, zeolites, and apophyllite attributed to New Haven, but these quarries (most notably Pine Rock Quarry in Hamden) are now mostly not in the city due to subdividing mentioned above. The extreme NW corner of New Haven, west of state Route 69 and Forest Road, is underlain by Ordovician to Silurian metamorphic rocks of the Orange-Milford Terrane, with the nonconformity between these and the overlying New Haven Arkose exposed at the foot of powerline pylons at the retail plaza on state Route 63 immediately north of state Route 15. The Milford-Orange Terrane includes serpentinite bodies, one of which, in the Malby Lakes area of West Haven, was quarried by Benjamin Silliman in the 1810s, but none of these is within New Haven's limits due to subdivision. In the extreme SE corner of the city, at Lighthouse Point, is an exposure of granite that is part of the Gander Terrane.
Coordinates are for the middle of the town green, which is the center of the original nine squares laid out for development by the first European settlers.

Detailed Mineral List:
| β Andradite Formula: Ca3Fe3+2(SiO4)3 Habit: modified rhombic dodecahedrons Colour: dark-brown to jet-black, yellowish-brown Description: occur on the vertical surfaces of the columns where they have been exposed in the process of quarrying. The spot at which they are found is in the body of the dike, far away from the line of contact with the sandstone; they are scattered here quite freely over a considerable surface. Associated with magnetite, apatite, pyroxene now altered to chlorite, calcite, and also in traces chalcopyrite and sphalerite. Called the melanite variety by Dana. |
| βͺ Andradite var. Melanite Formula: Ca3(Fe3+,Ti)2(SiO4)3 Habit: rhombic dodecahedral, often in nearly parallel positions in rosettes Colour: dark-brown to jet-black, occasionally yellowish-brown Description: Rosettes reach to about 2 cm across. |
| β 'Apophyllite Group' ? Formula: AB4[Si8O22]X · 8H2O Description: May be in reference to minerals found at the Pine Rock Quarry just over the border in Hamden. |
| β Aragonite Formula: CaCO3 Habit: radiating acicular Colour: white Description: Sprays in vein less than 1 cm long |
| β Calcite Formula: CaCO3 Localities: Habit: rhombohedral, scalenohedral Colour: white Description: Tiny rhombs and larger scalenohedra in vein in arkose. References: |
| β Chalcopyrite Formula: CuFeS2 Description: Traces. |
| β 'Chlorite Group' Localities: Habit: pseudomorphic alteration of the pyroxene Colour: green Description: minute dark-green crystals, destitute of luster; they are crowded together on the surface of the rock. These crystals are strictly pseudomorphs after pyroxene, for though having unquestionably its form, they are so soft as to be easily cut with a knife (Dana, 1877) |
| β Epidote Formula: (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH) Description: A completely unsubstantiated guess. |
| β Epidote var. Tawmawite Formula: {Ca2}{(Al,Fe3+,Cr)3}(Si2O7)(SiO4)O(OH) Description: A completely unsubstantiated guess. |
| β Fluorapatite Formula: Ca5(PO4)3F Habit: acicular Colour: yellowish-green Description: Minute prisms, in and among the pyroxene and penetrating the garnets. Referred to as "apatite" by Dana. |
| β Magnetite Formula: Fe2+Fe3+2O4 Habit: octahedral Colour: black Description: brilliant octahedrons, scattered sometimes thickly, sometimes sparsely, over the surface of the rock; it uniformly underlies the garnet where they occur together (Dana, 1877). |
| β Prehnite ? Formula: Ca2Al2Si3O10(OH)2 Description: May be in reference to minerals found at the Pine Rock Quarry just over the border in Hamden. |
| β 'Pyroxene Group' Formula: ADSi2O6 Habit: altered to chlorite Colour: green Description: minute dark-green crystals, destitute of luster; they are crowded together on the surface of the rock. These crystals are strictly pseudomorphs after pyroxene, for though having unquestionably its form, they are so soft as to be easily cut with a knife (Dana, 1877) |
| β Quartz Formula: SiO2 Localities: Habit: prismatic Colour: colorless to milky Description: Tiny crystals and massive in vein in arkose. References: |
| β Quartz var. Jasper ? Description: In "rolled masses", now called cobbles of boulders in unconsolidated overburden. Noted as "near" New Haven, so may not be within the modern city limits. References: |
| β Sphalerite Formula: ZnS Description: Traces |
| β 'Stilbite Subgroup' ? Formula: M6-7[Al8-9Si27-28O72] · nH2O Description: May be in reference to minerals found at the Pine Rock Quarry just over the border in Hamden. |
