Miles ... [et al.]]. Scale 1:120,000 ; Lambert conformal conic proj., zone 7N (W 150°00’--W 124°00'/N 68°00'--N 60°00’). [Ottawa] : Natural Resources Canada, 2015. 1 map : col. Geological Survey of Canada, open file ; 7862 Relief shown by shading. Includes text, index maps and location map. Errata: data for two surveys in Alaska (AK110 and AK160) were imported into the UTM grid using the wrong UTM zone, with resulting errors visible in four small areas of the map, and also present in corresponding data available in the Geoscience Data Repository; and in the map’s descriptive notes, one survey (no. 21) had been omitted from the table of GSC surveys and from the corresponding index map. Includes bibliographical references. "This map is a compilation of aeromagnetic surveys over Yukon and eastern Alaska. Aeromagnetic surveys measure the total intensity of the earth's magnetic field. The field was measured by a magnetometer aboard an aircraft flown in parallel lines spaced at 200 m to 10000 m across the map 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"--Provided by publisher. gccst Geological maps gccst Geophysics gccst Magnetism Miles, Warner, 1959- Canada.
