[BPT05-19] The latest research on REY-rich mud in the Pacific Ocean
Keywords:deep-sea mineral resource, REY-rich mud, Minamitorishima Island, western North Pacific, South Pacific
In the presentation, we report 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 introduce our latest findings including the basin-wide spatial distribution of the muds with a high resource potential and various genetic components identified in the western North and central to eastern South Pacific REY-rich muds. Our accumulation and integration of the scientific knowledge about deep-sea sediments including REY-rich mud strongly suggest an intrinsic linkage between the formation of deep-sea mineral resources and Earth system dynamics such as climate change, geochemical cycles, and plate tectonics, which can offer new insights into resource geology, oceanography, paleoclimatology, and solid earth science.
