The alternations of sedimentogenic and asedimentogenic belts on the continental shelf and slope are distinctive features in the East Asia marginal basins. These sedimentogenesis characteristics are conditioned by the terrigenous material supply and their distribution patterns. Facial analysis of the marginal basins reveals a number of typical facial models which are comparable with the geosynclinal and subplatform formations of the ancient basins. The paragenetical situation and simultaneous coexistence of these facial models in the modem marginal seas indicate that the ancient formation could be deposited in the same way

at the same time and even in the same basin.
