Magnetic modelling in the St. Mary Block, Purcell anticlinorium, Canadian Cordillera, British Columbia [electronic resource] / M.D. Thomas. [Ottawa] : Natural Resources Canada, 2018. 22 p. : charts (mostly col.), ill. (mostly col.), col. maps. Current research, 1701-4387 ; 2018-2 Includes bibliographical references. "The St. Mary Block is a half-anticline within the dominantly metasedimentary Mesoproterozoic Purcell anticlinorium, southeast Canadian Cordillera. It is comprehensively mapped geologically, but knowledge of its deeper structure is limited essentially to segments of two seismic lines. Widespread magnetic coverage in the area affords a means to investigate the Block's upper crustal structure"--Provided by publisher. Includes abstract in French.
