Abstract
The spatial distribution of the lithospheric magnetic anomalies Maps of the spatial distribution of the lithospheric magnetic anomaly field for three hot spot areas: Hawaii, Afar and Iceland were analyzed in order to solve the interdisciplinary problem of the hot spots and mantle plumes impact on the lithosphere. To construct the plume and hot spot magnetic images the experimental data of the CHAMP satellite was used which were obtained in the last year of its operation, 2010, at a minimum level of 280-260 km. The database of the anomalous magnetic field parameters has been supplemented for areas where materials on these hot spots were already available, and new data has been obtained for the part of the Pacific Ocean where the Hawaiian hotspot is located. Maps of lithospheric magnetic anomalies have been constructed for the central Pacific Ocean, the East African rift zone and the North Atlantic. It is shown that magnetic images of the various types of hotspots: oceanic Hawaiian, continental Ethiopian and island Icelandic appear themselves in different ways, which reflect the consequences of tectonic processes that took place earlier and are currently developing in the territories under consideration. It is shown that the use of satellite observations of the lithospheric magnetic field in areas with mantle plume activity when being combined with other geological and geophysical regional data could add considerable information to the overall picture of the tectonic processes study.
