520 ‡aTotal magnetic intensity anomaly (relative to the earth's magnetic field), color coded, scale 1:250,000. Interpretation of magnetic data collected from airborne surveys, the map colors indicate the distribution and concentration of magnetic minerals (primarily iron-bearing) within the upper crust of the earth.
