Abstract:
A simple numerical technique that permits the determination of the
magnetization of a two dimentional body, producing a magnetic anomaly
as well as a gravity anomaly, is presented. This technique involves the comparison
of the Fourier transform of the magnetic anomaly, computed starting
from the gravity anomaly using the Poisson relationship, with the Fourier
transform of the observed magnetic anomaly and can easily be extended to
the three dimensional case (to determine the direction of magnetization only)
As most of the magnetized basic rocks that produce magnetic anomalies also
produce gravity anomalies, the present technique has useful practical
applications in the interpretation of magnetic anomalies.
