摘要：

The Kerguelen Plateau is the largest submarine rise in the southern Indian Ocean. The heterogeneous structure of the crust, plume magmatic activity, and different ages of the adjacent basins indicate different structures of different marginal zones of the plateau. On the basis of geological and geophysical information, various morphodynamic types of margins of the Kerguelen Plateau are identified. Analysis of the bottom topography and potential field data, together with two-dimensional density modeling, allows us to specify the deep structure of the tectonosphere in the Kerguelen Plateau margins and take a fresh look at their nature.
