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.
