Abstract
Kerguelen Plateau is the largest underwater rise in the southern Indian Ocean. The heterogeneous structure of the crust, plume magmatic activity, as well as a different ages of adjacent basins — all this indicates a different structure of the marginal zones of the plateau. In this work, on the basis of geological and geophysical information, various morphodynamic types of the margins of the Kerguelen plateau are identified. An analysis of the bottom topography and data of potential fields together with two-dimensional density modeling allows us to specify the deep structure of the tectonosphere of the margins of the Kerguelen plateau and take a fresh look at their nature.
