Abstract
We have done a comparative analysis of quantitative parameters for Pleistocene sediments from pelagic zone of the Indian Ocean and submarine parts of its continental margins (for five key areas). The distribution areas, thicknesses, and volumes of main lithological types and groups have been analyzed. Dry sediment masses and their accumulation rates have been calculated. In the Neopleistocene compared to Eopleistocene, the fluxes (absolute masses) of all components of bottom sediments have been increased both in the pelagic zone and on the continental margins. Biogenic sedimentation was more important for facies structure of pelagic zone than (on average) for continental margins.
