Analysis and Inversion of Potential Field Data in the Wavelet Domain

By analysing potential field data in the wavelet domain and performing a multi scale edge detection we can automate what in geologic jargon is commonly called 'worm analysis', i.e., the traditional visual inspection of gravity and aeromagnetic data in order to detect shallow faults, lineaments, contacts etc. More importantly, with the use of an appropriate wavelet, defined by the physics of the problem, information about the depth extent of major geological features can be obtained and consequently the method can be seen as an inversion strategy.
