Abstract

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.

基于地质和地球物理数据的克格伦高原边缘带构造层结构

摘要

克格伦高原是印度洋南部最大的海底上升。地壳的非均质结构，羽状岩浆活动以及相邻盆地的不同年龄表明了高原不同边缘带的不同结构。根据地质和地球物理信息，确定了克格伦高原边缘的各种形态动力学类型。对底部地形和势场数据的分析，再加上二维密度建模，使我们能够确定克格伦高原边缘的构造层的深层结构，并重新审视它们的性质。
