『Abstract
　The grain-size composition of nonlithified sediments in the Indian, Pacific, and Atlantic oceans is studied. Grain-size features of the major lithogenetic types of deep-water sediments are determined. The genetic interpretation of results obtained is given. Trends of the fractionation of sandy-silty and pelitic materials in pelagic zones of sedimentation basins are revealed.』
