  1. Deep Equivalent Layer Total Field Anomaly Shallow Equivalent Layer Original total magnetic intensity separated into shallow and deep equivalent source layers; contour intervals = 5 nanotesla.

  2. First Vertical Derivative (historic) Total Field Anomaly Second Vertical Derivative (historic) Note reduction of regional slope with increasing order of differentiation

  3. TMI Reduced to Pole Total Field Anomaly Pseudogravity of TMI Pseudogravity is the vertical integral of the reduced to pole anomaly; consequently it has significantly lower frequency content

  4. Edge Detection on Pseudogravity Horizontal Gradient of Pseudogravity Pseudogravity of TMI Analytic Signal (Total Gradient) of Pseudogravity

  5. Edge Detection on Pseudogravity Compared with TMI Horizontal Gradient of Pseudogravity Total Field Anomaly Analytic Signal (Total Gradient) of Pseudogravity

  6. Edge Detection on RTP Horizontal Gradient of RTP TMI Reduced to Pole Analytic Signal (Total Gradient) of RTP Note enhancement by turning off the lowest color band

  7. Total Field Anomaly Horizontal Gradient of Pseudogravity Horizontal Gradient of RTP Analytic Signal (Total Gradient) of Pseudogravity Analytic Signal (Total Gradient) of RTP
