I have just started using the Euler 3D Deconvolution with Montaj. The
program runs fine, but I am not sure that I am optimising the parameters
appropriately.
Specifically I have an aeromagnetic TMI data set with both shallow
(including culture) and deep basement magnetic features. I have no
problem in getting fits to shallow features. Linear trends in the basement
(positive and negative) are clearly visible on the horizontal and vertical
derivative grids that are calculated from the original TMI by Euler.
However I cannot get any Euler depth fits on most of these, despite
experimenting with SI values from 0-3 and window widths from 3-20 and
generous depth and window tolerances. I also upward continued and
resampled the grid from 100m to 300m and carried out similar experiments,
but still cannot get many fits.
Can anyone offer any suggestions....?
Would using a reduction to the pole (the area is in Canada) rather than the
TMI offer any improvement? What about using Analytic signal?
