Abstract
Si, Ti, Al, Fe, Mn, Ca, Mg, K, Na, P and Sr, Ba, Rb, Ga, V, Zr, Cr, Ni, Co, Cu, Zn, Pb, Nb, Y, Th, La in the core S01 were analyzed and the pattems of their enrichment are discussed. Enrichment of Na, Fe, Mn, Ba, Cu elements in the core indicates volcanic material are an important source of the sediments in the area. The enrichment frequently varying with the deposition process shows bottom volcanism is frequent in the area and that the studied area is a margin basin with distinct oceanic characteristics.
The abnormal enrichment of Mn at the layers (0–15 cm and 665–670 cm) of the core could be closely related to and so, indicate, the wide deposition hiatus that have occurred in the West Pacific Ocean and adjacent margin seas since Late Pleistocene.
