In contrast to palaeomagnetic studies that consider outcropping rocks, the analysis of aeromagnetic anomalies can give averaged information about large volumes of deep-seated rocks. The recognition and analysis of anomalies having an ‘abnormal shape’ in the central Mediterranean area have yielded original and interesting results in recent years. Accurate interpretation of these anomalies gives information on the nature of magnetization of the deep crust and on the geodynamic history of this region. Results suggest that the southern Italian area can be divided into zones which experienced different tectonic rotations in both clockwise and anticlockwise senses. The pattern of rotations deduced in this way agrees well with that determined by standard palaeomagnetic analyses.
