Using of the adaptive simulated annealing (ASA)‎ for quantitative interpretation of self-potential anomalies due to simple geometrical structures

Abstract EN

A quantitative interpretation method of self-potential field anomalies has been proposed in this work.

The method is designed and implemented for determining the center depth, electric dipole moment or magnitude of polarization, polarization angle, and geometric shape factor of an underground buried body from field data related to simple geometric structures such as cylinders, spheres and sheet-like bodies.

The method is based on mathematical modeling by using the global optimization method of which known as an adaptive simulated annealing (ASA).

The utility and validity of this method have been first demonstrated on a theoretical example using simulated data generated from a known model with different random errors and a known statistical distribution, where a very close agreement was obtained between assumed and evaluated parameters of the model.

Subsequently, field data from Germany, India and Turkey have been considered for which the interpreted results by other interpretation methods are available for comparison.

The agreement between the results obtained by our proposed method and other methods is good and comparable.
