Outline of Final Research Achievements |
Gephysical and geochemical studies have been performed in order to establish exploration methods for REY-rich mud and ferromanganese nodules in the Minamitorishima EEZ and to elucidate their distributions and ore genesis. Our study produced the following results: (1) Exploration methods for the REY-rich mud and ferromanganese nodules using sub-bottom profiler and multibeam echo sounder have been successfully established. (2) Distributions and resource potentials of the resources have been estimated based on the exploration results. (3) It has been suggested that the presence of both the REY-rich mud and ferromanganese nodules is the result of deep-sea current flowing through the Minamitorishima EEZ.
