Induced magnetization in the intermediate to deep crust is insufficient to justify regional magnetic anomalies. This is an unresolved problem, that cannot be completely explained by induced and viscous magnetization. In this context, the contribution of remanent magnetization in the Southern Italian Region has been investigated from a study of long‐wavelength magnetic anomalies. By means of a shape analysis, several anomalies were found which indicate a total magnetization vector direction different from the induced one. From the good correspondence between these deduced declinations with palaeomagnetic and palaeotectonic data, we infer a remarkable manifestation of remanent magnetization in the intermediate‐crust.
