The Indian Ocean: Aseismic Ridges, Spreading Centers, and Oceanic Basins

  • Chapter
The Ocean Basins and Margins

Abstract

The Indian Ocean has often been considered as the most complex of the world’s major oceans. In fact, it has been the last of the three oceans to be studied, and now, in spite of its real complexity, the Indian Ocean appears to be as well understood as the other oceans. Although immense areas are nearly unexplored to this day, in particular the whole region south of 58°S, it is now possible, by using the fracture zones and observed magnetic lineations, to identify the major events which have contributed to the formation of this ocean, at least since late Cretaceous time. The Mesozoic geological history of the Indian Ocean still remains uncertain, and its clarification needs the collection of complementary data, mainly in the southern part of this ocean.
