Organic carbon content and ^<14>C age have benn measured for solid organic materials of plant residues in two turbidite layers of a piston core (KT7819-24), and of a chip picked up from a pebble layer in another piston core (KT7819-21), from Suruga Trough, off Central Japan. Results are summarized in Table 1. These results support the idea, 1) proposed in our previous paper (Nakamura et al., 1990) that the plant residues in the turbiditite layers of the core (KT7819-24) were originated by river flood, and mixed with older sediments of shallow sea when the sediment layer was overloaded and falled down forming turbidity currents, 2) that the pebble layer distributed in the axial zone of the Suruga Trough of over 2,000 meters deep is very recent sediments of some kinds of glavity flow, as estimated by Sato (1962) concerning his piston core sediments.
