Deep Structure of the Arctic and Antarctic according to Component Magnetic and Gravitational Anomalies
Abstract The results of a study of the deep structure of the Earth’s polar regions based on the interpretation of gravitational anomalies, geomagnetic-field anomalies, and seismological data are presented. Based on measurements on the CHAMP and Swarm satellites, vector models of the magnetic field o...

| 520 | |a Abstract The results of a study of the deep structure of the Earth’s polar regions based on the interpretation of gravitational anomalies, geomagnetic-field anomalies, and seismological data are presented. Based on measurements on the CHAMP and Swarm satellites, vector models of the magnetic field of the Arctic and Antarctic have been verified. To study the magnetically active zones and roots of the lithosphere observed in near-Earth space, deep sections were constructed. Density sections were obtained from gravitational anomalies, and magnetic sections were obtained from anomalies in the modulus and components of the geomagnetic field. To estimate climate risks, a joint analysis of deep sections with satellite data on variations in the ice cover of the polar regions was carried out. It showed that vertical thermofluid channels play a significant role in the process of ice melting. Distinctive features of melting centers caused by endogenous factors are revealed. The migration paths of fluid flows destroying the ice cover are visualized in sections in the form of channels with reduced magnetic and density properties. The conducted studies allows to understand the possible reasons for the localization of centers of ice and permafrost destruction. It was shown that in the permafrost zones of ancient basement blocks, thermal areas of through taliks arise under the influence of heat flows of fluid-supply channels. Melting areas can be represented by hot spots of ore clusters, within which mineral deposits are concentrated under the influence of hydrothermal flows of mineralized fluids. Studies of the deep structure of the Arctic and Antarctic are of scientific and applied importance for solving exploratory geological and geophysical problems and estimating climate risks. | ||

To estimate climate risks, a joint analysis of deep sections with satellite data on variations in the ice cover of the polar regions was carried out. It showed that vertical thermofluid channels play a significant role in the process of ice melting. Distinctive features of melting centers caused by endogenous factors are revealed. The migration paths of fluid flows destroying the ice cover are visualized in sections in the form of channels with reduced magnetic and density properties. The conducted studies allows to understand the possible reasons for the localization of centers of ice and permafrost destruction. It was shown that in the permafrost zones of ancient basement blocks, thermal areas of through taliks arise under the influence of heat flows of fluid-supply channels. Melting areas can be represented by hot spots of ore clusters, within which mineral deposits are concentrated under the influence of hydrothermal flows of mineralized fluids. Studies of the deep structure of the Arctic and Antarctic are of scientific and applied importance for solving exploratory geological and geophysical problems and estimating climate risks.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Latysheva, O.

Deep Structure of the Arctic and Antarctic according to Component Magnetic and Gravitational Anomalies |
| abstract |
Abstract The results of a study of the deep structure of the Earth’s polar regions based on the interpretation of gravitational anomalies, geomagnetic-field anomalies, and seismological data are presented. Based on measurements on the CHAMP and Swarm satellites, vector models of the magnetic field of the Arctic and Antarctic have been verified. To study the magnetically active zones and roots of the lithosphere observed in near-Earth space, deep sections were constructed. Density sections were obtained from gravitational anomalies, and magnetic sections were obtained from anomalies in the modulus and components of the geomagnetic field. To estimate climate risks, a joint analysis of deep sections with satellite data on variations in the ice cover of the polar regions was carried out. It showed that vertical thermofluid channels play a significant role in the process of ice melting. Distinctive features of melting centers caused by endogenous factors are revealed. The migration paths of fluid flows destroying the ice cover are visualized in sections in the form of channels with reduced magnetic and density properties. The conducted studies allows to understand the possible reasons for the localization of centers of ice and permafrost destruction. It was shown that in the permafrost zones of ancient basement blocks, thermal areas of through taliks arise under the influence of heat flows of fluid-supply channels. Melting areas can be represented by hot spots of ore clusters, within which mineral deposits are concentrated under the influence of hydrothermal flows of mineralized fluids. Studies of the deep structure of the Arctic and Antarctic are of scientific and applied importance for solving exploratory geological and geophysical problems and estimating climate risks. © Pleiades Publishing, Ltd. 2022.
