The maps in [[:file:using-magnetics-in-petroleum-exploration_fig14-3.png|Figure 2]] are examples of a residual map (A) that was calculated from the total intensity magnetic map (B). The grid and small circles on the total intensity map are the flight path lines [approximately [[length::2 km]] (1.2 mi) apart] and location points for the flight lines. The total intensity map strikingly does not resemble the residual map and would be of limited value for delineating basement fault blocks.
