Presentation on theme: "Deep Equivalent Layer Total Field Anomaly Shallow Equivalent Layer"— Presentation transcript:

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
