摘要

深海钻探与大洋钻探发现的许多古海洋事件和古环境变化,控制着海洋矿产的形成与分布,并为研究海底成矿作用提供了大量科学资料。大洋钻探及其他有关研究已经证明,南极底层水和上升流的发育,硅质生物的高生产力,以及始新世、渐新世、中新世与上新世的沉积间断,都有利于多金属结核、富钴结壳和磷灰石的形成。因此,深海钻探和大洋钻探对于海洋成矿理论有重大贡献。

Abstract

    DSDP and ODP have revealed numerous paleoceanographic events and paleoenvironmental changes which controlled the formation and distribution of marine mineral resources, and provided vast amount of scientific data for the study of marine mineralization.
    ODP and other related studies have proved that the development AABM and upwelling, high siliceous bioproductivity, and hiatus during Eocene, Oligocene, Miocene and Pliocene were favourable for the formation of polymetallic nodules, Co-rich crusts and phosphorites. Thus,DSDP and ODP have greatly contributed to the theory of marine mineralization.
