The bedrock geology of Newington consists of Triassic-Jurassic Hartford Basin continental sedimentary rocks (arkosic sandstones, mudstones, and lacustrian black shales) interlayered with three basalt flows. The bedrock is heavily faulted, especially to the west near the border with New Britain, with some exposures showing steeply dipping, N45E trending faults every few meters. Mineralization is hosted primarily by the fault veins (low temperature hydrothermal deposition) and by gas cavities in the basalt.

There are numerous localities where the fault veins were well exposed by road cuts and other construction sites, which all show a similar suite of minerals - primarily dolomite, calcite, Herkimer-type quartz, barite, bitumen (mobilized from the lacustrian black shales), and sulfides. Most of these localities are very similar to those described by Scovil (2008), Hubert et al (1992), and Gray (1982).

Numerous small traprock quarries and construction site exposed the lava flows. Besides the vein mineralization, gas cavities in the basalt host the typical suite of datolite, prehnite, quartz, calcite, zeolites, apophyllite, etc.
