Abstract

Many researchers attempted to get insights into the evolution of the crustal spreading in the Tyrrhenian sea by studying the Earth's total magnetic field intensity anomalies. Unfortunately, the strong interference phenomena between nearby magnetic anomalies in the Tyrrhenian Sea and their dipolar shape at mid latitudes are serious obstacles to a simple interpretation of magnetic maps in this region. In this paper we give a contribution to the interpretation of the magnetic field in the Tyrrhenian Sea, by a careful analysis of the main properties of the field, as evidenced by a comparison of the measured total magnetic field with its modulus. Such comparison will allow a safe identification of the normally and reversely magnetized sources to magnetic field.
