REE Geochemistry and Resource between Co-Rich Crust and Basement in the Pacific Ocean: Based on Magellan Seamount Sample Research

Using Magellan Seamount samples in the Pacific area to carry out the REE chemical analysis and microscopic descript,this paper analyze the content of REE between the basement rock and co-rich crust, distribution characteristics, distribution pattern.The results show that: the three layers samples contain high value, total quantity is about 1000×10-6, compared with normal deep sea sediments, foraminiferal nuclear shell and sea water content of rare earth elements10 ~ 100 times; Basement and co-rich crust have shown consistent in distrubution mode, REE content is perfectly high, co-rich crust of REE is mainly controlled by overlying seawater on the rock points erosion. volcanic eruption, ocean floor basalt weathering and biological chemical deposition on the formation of the crust also has certain influence. REE as a huge resource is superior to exploit, The comprehensive development and utilization of mineral resources provided good premise, it is possible to createREE resource utilization of the new way.
