The Percentage errors in depth estimation from magnetic anomalies due to dyke-like bodies, having various depths and inclination angles, are calculated. Two methods have been used to estimate the depth of these bodies and then their percentage errors in depth estimation are compared. These methods are the well-known slope-half slope method and the method adopting procedure through using Fraser filter. The two methods have accompanied various percent errors in depth estimation for models having various magnetic parameters. The comparison between the calculated error values obtained from the two methods show that the differences between the maximum and minimum percent error with various inclination angles and depths are smaller for depths estimated by using Fraser filter procedure. Such results highlight the lesser mistakes that can be achieved if the procedure of depth estimation using Fraser filter is considered and in addition, the ease of the application of this procedure compared with slope method. |
