Origin of the ultramafic complex at duke island, southeastern alaska. T. IRVINEl M cM aster University, Hamilton, Ontario. The Duke Island ultramafic complex crops out in two areas that total 9 square miles. Rocks within the complex are comprised of olivine, clinopyroxene, hornblende and ferriferous oxides and are classified as dunite, peridotite, olivine pyrox-enite and hornblende pyroxenite; all are devoid of plagioclase and orthopyroxene. A pegmatite of hornblende and anor-thite is closely associated and probably comagmatic, but abundant gabbro surrounding the complex has been.

Duke Island, 59 square miles in area, is at the southern end of southeastern Alaska. The granitic rocks may be of Cretaceous age. Primary gabbroic rocks are dominantly two-pyroxene gabbro and norite. Their plagioclase is An50-An70. Ultramafic rocks crop out as two main areas and more than a dozen minor ones. The rocks in the main areas probably are continuous at depth forming the Duke Island ultramafic complex
