[SCG64-09] REY-rich mud in the western North Pacific Ocean: An overview and implication for Earth system dynamics
Keywords:seafloor mineral resources, rare-earth elements, REY-rich mud, deep-sea sediment, Earth system
Here we overview the progress of our researches on the REY-rich mud within the Minamitorishima EEZ towards the world’s first development of deep-sea mineral resources. Moreover, we also discuss the controlling factor(s) of the formation and distribution of the extremely REY-rich mud. Our accumulation and integration of the scientific knowledge strongly suggest an intrinsic linkage between the genesis of deep-sea mineral resources and Earth system dynamics such as climate changes, ocean circulation, plate tectonics, and global geochemical cycles.
