Özet

In this paper, a FORTRAN 77 computer program that estimates the inclination and declination of the magnetization of a body causing a magnetic anomaly is presented. The program searches for maximum correlation in between the pseudogravity anomalies at ranges of body magnetization and gravity anomalies caused by the same formations. The pseudogravity transformation is performed each time for an array of inclination and declination angles. Test cases demonstrate that the method can be used with confidence. An example of aeromagnetic and gravity anomalies from Northern Central Turkey, shows maximum correlation at -22°of declination of body magnetization. This result correlates well with the previous research on paleomagnetic and tectonic work revealing an anticlockwise rotation of Central Turkey.
