Advances on studies of geochemistry and paleoceanography of the Co-rich crust

本文综述了近年来国内外富钴结壳地球化学与古海洋学研究的新进展 .概述了富钴结壳地球化学的研究成果 阐述了富钴结壳中元素的扩散及与周围海水的交换 ,基岩和磷酸盐化事件对富钴结壳组成的影响 分别介绍了稳定同位素 (Pb、Nd和Hf的稳定同位素 )、放射性同位素 (Be、U和Th的放射性同位素 )及元素 (常量和微量元素、稀土元素 )在富钴结壳古海洋学研究上的应用 .

The current advances of the studies of geochemistry and paleoceanography of the Co rich crust are reviewed in this paper. We summarize the study of geochemistry of the Co rich crust, and explain the diffusion of elements in the Co rich crust and the exchange with ambient seawater. Besides, we discuss the effect of phosphatization and substrate rocks on the composition of the Co rich crust. We also introduce the application of stable isotopes (including the stable isotopes of Pb, Nd, and Hf), radioactive isotopes (including the radioactive isotopes of Be, U and Th), and elements (including the major elements, minor elements and rare earth elements) to the study of paleoceanography of the Co rich crust.
