First vertical derivative of the magnetic field, aeromagnetic survey of the Llewellyn area, NTS 104-M/9, 10, 15, 16 and parts of 104-M/11, 14, British Columbia / [authors, O. Boulanger and F. Kiss].: M183-2/8291E-PDF

"Aeromagnetic surveys measure the total intensity of the earth's magnetic field. The field was measured by a magnetometer aboard an aircraft flown at 150 m in parallel lines spaced at 400 m altitude across the survey area. The magnetic field reflects magnetic properties of bedrock and provides qualitative and quantitative information used in geological mapping. Understanding the geology will help geologists map the area, assist mineral/hydrocarbon exploration activities, and provide useful information necessary for communities, aboriginal associations, and government to make land use decisions. This survey was flown to improve our knowledge of the area. It will support ongoing geological mapping and resource assessment"--Summary provided by publisher.
