摘要：
We compared the arithmetic average chemical composition of main types of Pleistocene sediments in the Indian and Atlantic oceans, and average chemical composition of the Pleistocene in both oceans as well. As the base for comparison, we used data from the International project of deep-sea drilling reports (phases DSDP, ODP, IODP) and other references. It was revealed that the results of comparative analyses of the mean weighted chemical composition were determined by masses of the dry sediment matter. Domination of the Atlantic mass accumulation rates over the Indian Ocean ones was due to markedly larger catchment areas, influence of more significant humid climate, and enhanced primary production.
