Roadcuts made in the early 1980s to create this interchange exposed the very northern end of the Jurassic West Rock Diabase sill/dike system and Upper Triassic New Haven Formation arkosic sandstone. Mineralization in the diabase was exposed on the I-691 eastbound off-ramp to Route 10 (calcite, datolite, barite, quartz) and in a pit near the NW corner of the interchange (mainly calcite).

Standard Detailed Gallery Strunz Chemical ElementsDetailed Mineral List:
| β Baryte Formula: BaSO4 References: |
| βͺ Calcite Formula: CaCO3 Habit: Scalenohedral to rhombohedral Colour: colorless, white, yellow, red-brown Fluorescence: orange-red (best under MW UV), white to pale blue (outer zone on some dogtooth crystals under LW UV) Description: At the off-ramp exposure the best crystals are translucent yellow dogtooth crystals to about 1.5 cm with good fluorescence. In the pit, the crystals are larger, to 2.5 cm and well formed but largely an ugly opaque red-brown from inclusions. References: |
| β Chalcocite Formula: Cu2S References: |
| β Chalcopyrite Formula: CuFeS2 References: |
| β Datolite Formula: CaB(SiO4)(OH) Habit: Typical roughly equant complexly formed. Colour: Pale lime green. Fluorescence: Spotty bright green zones under SW UV. Description: Well-formed glassy crystals in voids, from a druse to about 1 cm. References: |
| β Hematite Formula: Fe2O3 Colour: red Description: Mostly earthy material at the pit exposure. As micros in voids associated with datolite and chalcopyrite. |
| β 'Pumpellyite Group' Formula: Ca2XZ2[Si2O6(OH)][SiO4](OH)2A References: |
| β Quartz Formula: SiO2 Habit: Drusy Colour: colorless Description: Druses typically lining fracture voids. References: |
