Flavrian Lake Map Area includes about 12 square miles in Duprat and Beauchastel townships. This area was studied and mapped in detail for the Quebec Bureau of Mines during the summer of 1939. All available outcrops of rock were mapped by plane table and alidade surveys and examined. A large collection of specimens was made and during the following winter microscopic studies of rock specimens were carried out in the laboratories of McGill University. During the summer of 1940 the writer continued mapping for the Quebec Bureau of Mines on an adjoining area to the southwest of the Flavrian Lake sheet. Data from this area having a bearing on the problems of the Flavrian Lake area have been incorporated in this thesis. It was realized from the first that a thorough study of an area of this kind must include consideration of its relation to the surrounding rock formations and its position in the regional structure. Consequently an effort was made to assemble and correlate data from surrounding areas.
