Apparent magnetizations calculated from magnetic intensity depend on Z, and Pilkington attempts to remove this variableness by annihilating the topographic effect with the convolution of a topographic set from a seismic source (One would have to consult his references for a description of the topographic set.) having a crude contour interval of 300 m where maximal values are 1500 m. Then there are no data given to show that this surface is the surface of a magnetic basement. The largest element, an outcropping dome in the west with no corresponding anomaly on the intensity map, is not magnetic basement.
