摘要
Marine Co-rich crusts are important as potential mineral resources for Co, Ni, Cu, Mn, and other metals, as well as for the paleoenvironment signals stored in their stratigraphic layers. By means of analyzing relationships between Co-fluxes with amount of Co-deposited in the crust and crust thickness, the endowed crust thickness accounts for 6.10%~12.20% of the theoretical deductive thickness, which is close to Ku’s conclusion of "the crusts were actually growing for 4% of their lifetime". It is shows that the endowed number of crust thickness is reasonable and the obtained resource amount is reliable. This paper provides a new method for estimating the amount of Co-rich crust resources on seamounts in a whole deep-sea basin.
