A Precambrian layered gabbroic intrusion about 560 km^2 in area, of the Skaergaard type, crops out on the middle north coast of Labrador. Border zones and a Layered series are recognized, and have the following characteristics and approximate mean thicknesses. The intrusion displays extreme fractionation resulting in larvikite consisting of mesoperthite, fayalite, ferroaugite, and ore as the uppermost differentiate. Mineral variation and differentiation are described by means of quantitative mineralogy.
