大洋钻探与冲绳海槽地质

本文简要回顾大洋钻探计划实施十余年来所取得的成果，评述了西太平洋边缘海盆的研究概况，提出东海大陆边缘的重大地质问题是陆缘的构造演化历史和动力学过程，弧后扩张中心的热液成矿作用以及海洋沉积层序记录的古气候和古海洋环境变化，指出矿物－地球化学在大洋钻探研究中的重要性。

OCEAN DRILLING PROGRAM AND GEOLOGY OF OKANAWA TROUGH

Ocean Drilling Scientific Results in the past ten years are briefly introduced and the studies of the marginal basins of the West Pacific are reviewed. It is considered that the priciple problems of the continental margin in the East China Sea are tectonic evolution and dynamic process of the continental margin, hydrothermal mineralization in the spreading center of the backarc basin and changes of paleoceanograph and paleoclimate recorded in the marine sedimentary sequence. And mineral-geochemistry plays an important role in the study of the Ocean Drilling Core.
