Interpretation of magnetic anomalies of dikes by fourier

pure and applied geophysics Aims and scope Submit manuscript

Summary

Fourier transforms of theoretical magnetic anomalies of vertical and inclined dikes are computed. In all the cases it is shown that for a particular type of dike the amplitude spectra of horizontal and vertical components of the anomalous field remain exactly the same, whereas the phase spectra show a constant difference of π/2. The different parameters like depth to the top of the dike, width, susceptibility contrast and inclination can be calculated from the amplitude and phase spectra.
