| 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 paleoenviron-mental changes which controlled the formation and distribution of marine mineral re-sources,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 up-welling , high siliceous bioproductivity,and hiatus during Eocene , Oligocene , Miocene andPliocene were favourable for the formation of polymetallic nodules , Co-rich crusts andphosphorites,Thus,DSDP and ODP have greatly contributed to the theory of marine min-eralization. |
