Abstract

A

The properties of cross‐correlation functions for the case of gravity and magnetic total field anomalies produced by three geometric models of geological bodies (point‐mass, horizontal line‐mass, and vertical semi‐infinite rectangular prism mass distributions) are studied. This study is carried out on four cases of cross‐correlation: the whole curve of anomalies, a single branch of anomalies, the branch between the two inflexion points and the branch between the apex point and the inflexion point. In all cases, the crosscorrelation function can serve as a good indicator to discriminate the so‐called genetically related anomalies from those produced by different geological bodies situated on the same vertical line; but the best results are obtained using the cross‐correlation of the branches between the apex point and the inflexion point of the two geophysical anomalies.

A practical procedure is developed in order to undertake such analysis. The tests in some cases of real gravity and magnetic anomalies mapped in Romania show the validity of this practical procedure.
