The Indian Ocean: The geology of its bordering lands and the configuration of its floor
- James F. Pepper and Gail M. Everhart
The ocean realm, which covers more than 70 percent of the earth's surface, contains vast areas that have scarcely been touched by exploration. The best known parts of the sea floor lie close to the borders of the continents, where numerous soundings have been charted as an aid to navigation. Yet, within this part of the sea floor, which constitutes a border zone between the toast and the ocean deeps, much more detailed information is needed about the character of the topography and geology. At many places, stratigraphic and structural features on the coast extend offshore, but their relationships to the rocks of the shelf and slope are unknown, and the geology of the coast must be projected seaward across the continental shelf and slope.
The Indian Ocean, the third largest ocean of the world, has been selected for intensive study by an international group using all modern techniques to determine its physical characteristics. This report, with accompanying illustrations, has been prepared as a very generalized account of some aspects of the geology of the vast coastal areas of the northern Indian Ocean in relation to the bordering shelves and ocean deeps. Its general purpose is to serve as background reading.
