During the past three years the author has been engaged in studies of petrological and structural problems in an area including the Verna uranium deposit, located in northwestern Saskatchewan, three miles northeast of the Eldorado townsite (fig. 2). Field studies in the Verna area were supplemented by laboratory work at McGill University. The field work entailed surface mapping at a scale of one inch equals 100 feet, underground mapping at a scale of one inch equals 20 feet and the logging of several thousand feet of diamond drill core. Laboratory research included flat- and universal-stage thin-section study, mineral identification by X-ray diffraction and refractive index methods and wet chemical analyses to determine the contents of major elements in twelve rocks.
