Abstract:

A computer program in FORTRAN 77 is presented to invert the self-potential anomalies of sheet-like bodies. The program needs as input only the self-potential anomalies and their distances measured from an arbitrary reference in the profile and does not require the initial estimates of the body parameters of the model as in classical inversion techniques. The program measures the maximum and minimum anomalies, scales a few characteristic distances, calculates the initial values of the body parameters and improves them iteratively until a best fit is obtained between the observed and calculated anomalies.
