Abstract: Structural parameters can be determined directly from the geophysical anomalies having two-dimensional distributions for the potential fields. In order to achieve this, more equations are constructed for the same parameter to be determined. The special properties of analytical functions of the complex gradients and the Hilbert Transforms can be used to reach the above-mentioned situation. Certain structural parameters of two-dimensional bodies such as horizontal cylinder and horizontal sheets, were directly determined from the anomalies of the self-potential method. Hilbert Transforms, which can be carried out in two different ways using the Fourier Transform and convolution methods, were used to provide the conversion between the complex gradients of the anomaly. Structural parameters were then determined from the solutions of the constructed equations (anomaly, amplitude and phase functions).
