| الوصف: | The evolution of the Indian Ocean (Figure 1) since the Late Jurassic can be summarized in three main periods of seafloor spreading separated by two major plate boundary reorganizations [Royer, 1992]. From breakup of Gondwana at about 160 Ma (Figure 2) to the Late Cretaceous (-90/95 Ma), the opening of the Indian Ocean coincided with divergence of two superblocks, Africa-South America and Madagascar-Seychelles-India-Australia-Antarctica, which further fragmented in the Early Cretaceous (chron M0; Figure 3) into Africa-Madagascar-India and Australia-Antarctica. This two-plate system broke into a five-plate system during the Late Cretaceous with seafloor spreading between Madagascar and India-Seychelles and between Australia and Antarctica (Figures 4 to 8). The second major plate boundary reorganization occurred during the middle Eocene and coincided with the collision of India with Eurasia (Figures 8 and 9). The resulting plate boundary system has prevailed until present (Figures 8 to 12, and 1). The final events of this last phase were opening of the Gulf of Aden at about Chron 5 (10 Ma) and onset of the intraplate deformation in the Central Indian Basin between India and Australia (7 Ma). Evolution of the plate geometry is summarized in Figure 13. |
