Lithofacial types of sediments formed in certain geographic and physical-chemical conditions of the Pacific Ocean are distinguished and characterized. It is shown that the regular change of bottom sediment types forming a genetic series from the coast to the pelagic zone clearly demonstrates a leading role of biogenic-terrigenous sedimentation in their formation. In the pelagic zone of the ocean erosion of islands and seamounts, basalt volcanism of anticlinal uplifts, as well as exhalative contribution play some role in addition to the main source of terrigenous and pyroclastic material from continents. These sources do not change, but only complicate terrigenous sedimentation in the studied area of the ocean.
