Fourier analysis for quantitative interpretation of self-potential anomalies caused by horizontal cylinder and sphere

الملخص EN

Spectral analysis approach using Fourier transform has been developed for the interpretation of SP anomalies due to horizontal cylinder and sphere like structures.

Fourier amplitude and phase spectra related to the SP anomaly are derived and analyzed in order to adopt an interpretation procedure aiming at evaluating the geometric and physical parameters of these two studied structures.

The validity of the new proposed method has been tested on synthetic examples, where it has been found a close agreement between assumed and computed values.

A field example from the Ergani Copper district, Turkey has also been analyzed and interpreted by the proposed method, where an acceptable agreement has been
