Hypotheses of origin of ocean deep red clays are under discussion. On an example of the Pacific Ocean grain size, mineralogy and chemical composition of clays are considered. It is shown that they formed from atmospheric dust and andesite pyroclastics. Accumulation of the clays occurred through deposition particle-by-particle and by pellet transport.
