Abstract
An igneous complex exposed in Cumberland, Rhode Island, is one of a series of mafic intrusions that outline a northeast-trending lineament extending from the Preston Gabbro in Connecticut to the Boston, Massachusetts, area. The mafic complex in northern Rhode Island consists of a small body of melatroctolite adjacent to a much larger body (1 km**2) of anorthositic gabbro. The contact between the two rock types is not exposed, but inclusions of anorthositic gabbro and large cumulophyric crystal aggregates identical to the gabbro occur in the melatroctolite. Refs.
