Relief of acoustic basement of the Indian Ocean

Abstract

A new map of basement topography of Indian Ocean has been compiled using the data of geological geophysical and geomorphological studies carried out by International Expedition to Indian Ocean as well as other data. Main features are described of the basement surface and their resemblance is marked with recent submarine morphostructures. It indicates the single trend of relief-forming processes throughout the whole period of Mesozoic and Cenozoic evolution of the ocean floor.
