M. K. Kaban

  • Geophysical Center of RAS

Mikhail Kaban, Doctor of Physical and Mathematical Sciences, specializing in geophysics, geophysical methods of mineral exploration. A well-known scientist in the field of constructing complex models of the crust and upper mantle. Based on the methods he developed, 3-dimensional models of the lithosphere and upper mantle were built, which represent the main physical parameters: distributions of density, temperature, changes in the composition of the mantle, as well as basic rheological parameters. At the same time, global models hierarchically include detailed constructions for all continents and their parts. Based on the dynamic models he developed, the impact of mantle convection on the continental lithosphere, its stress state and deformations was studied. In particular, for the first time, a model of the root of the North American craton, displaced by mantle flows by 800-1000 km in the west-southwest direction, has been obtained.

Research interests: joint interpretation of gravimetric, seismic, geophysical and geological data for various applications: construction and interpretation of complex models of the earth’s crust and mantle at both regional and global levels; modeling of global mantle dynamics; study of isostasy, rheology, mechanical behavior of the lithosphere and the stress field caused by density inhomogeneities of the lithosphere; development of geophysical software: solving direct and inverse gravity problems (3D) taking into account information provided by other methods; cross-spectral analysis of the gravitational field and surface load to determine the effective thickness of the elastic lithosphere.

  • Systematic Studies of Natural Processes in the Arctic

    The Arctic zone of the Russian Federation today is the least explored region of Russia from the point of view of assessing the influence of various natural processes on the activities for its development and development. Warming in the Arctic is at least three times greater than the global average. A clear indication of such climate change is the rapid decline in the area and volume of Arctic sea ice. The results of calculations with climate models show that, perhaps, in the second half of the 21st century, the water area will be completely free of ice in the summer-autumn months. Such assessments speak in favor of intensifying the development of the Northern Sea Route as a promising transport route.
