Geomagnetic Anomalies: Lineaments

Geomagnetic anomaly maps can be interpreted according to either (i) To the electromagnetic (e.m.) Induction by the solar wind that generates telluric currents aimed to oppose the geomagnetic field originated by the deep geomagnetic dynamo, or (ii) By stray currents that outflow from the deep Earth’s circuitry. The results correlate with other morphological, geodynamic, and tectonic features, which represent a tool for the investigation of Earth’s interior. A few case studies are illustrated. It is thus shown that formerly unexplained morphological features displayed by geomagnetic anomaly maps can be justified in the framework of the planetary electrical circuit of air-earth currents.
