The general geology of an area of 50 square miles comprising the western half of La Motte township, Abitibi County, Quebec, is described. Peridotites and dunites occur as sills in Early Precambrian volcanic and sedimentary rocks. The belts of rock constitute part of the northern limb of a major anticlinorium. Granitic rocks of the Preissac-La Motte-La Corne batholithic complex probably derived from a common magma chamber occupy about 75 per cent of the map-area. The younger muscovite- and biotite-bearing quartz monzonite masses contain a higher percentage of potash feldspar than the biotite granodiorite masses.
