Exponential approach to estimate the Curie-temperature depth
To utilize the power density spectra of magnetic anomaly is a classical routine in the estimation of the Curie-temperature depth. Many applications of this technique are encountered in the geophysical literature in spite of the difficulty arising from the selection of the points for the slope of the straight line on the power density graph. In this study, a different approach for the estimation of the Curie-temperature depth from magnetic data was introduced. It is based on the analytical solution of the exponential equations obtained from the Fourier transformation of the magnetic data. The proposed approach has been tested on the synthetic magnetic anomalies originated by single prism and multi-prisms. According to encouraging test results, this technique was also treated on the field data which were studied to estimate the top and bottom depths by using power spectra and optimization solutions.
