| Abstract: | 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. |
