Abstract

The method and results of 3D simulation of the structure of the tectonosphere in the SW Indian Ocean based on gravity field data are presented. The study included the formation of 3D-density models for several areas covering large tectonic structures in the SW Indian Ocean. The formation of 3D-density models of the structure of the tectonosphere was based on the results of structural analysis, which had been performed earlier for the gravity and anomalous magnetic fields, and 2D-density simulation along profiles crossing large structures in the study region. As a result of the 3D simulation, maps of the Moho discontinuity and maps of the density distribution in the oceanic crust were built for the largest structures of the region.
