Satellite Regional Magnetic Anomalies as a Reflection of the Geological and Geophysical Properties of the Lithosphere (According to Champ Data)

Resumo

The possibilities of the use of satellite data to study lithospheric magnetic anomalies in remote and poorly studied regions are analyzed. The experiment uses data from CHAMP satellite measurements of the geomagnetic field at altitudes of ~280–320 km. Maps of the magnetic field over the territories of the North Atlantic Province, the Central Asian Fold Belt, and the Rhodope mountain range (Bulgaria) are given. The possible nature of lithospheric magnetic anomalies and their connection with deep structures and active tectonic processes in the lithosphere of the studied provinces are examined. The interpretation of the obtained maps shows that the lithospheric anomalies of the geomagnetic field are associated with modern, large-scale, geological and tectonic structures of the studied areas. The results are of interest for further complex geological and geophysical studies and the construction of valid models of the evolution of the lithosphere.
