The series of 15 schematic maps of mass accumulation rates of abiogeno
us matter (MAR AM) distribution in the sediment sequence of the Indian
Ocean from the Necomian to the Late Pliocene is described. The averag
e values of MAR AM, concentrations, masses and intensities of accumula
tion are obtained. The stages of terrigenous flux evolution in the Ind
ian Ocean are suggested.
