[M-ZZ41] Marine manganese deposits: from basic to applied sciences

Wed. May 23, 2018 10:45 AM - 12:15 PM A11 (Tokyo Bay Makuhari Hall)

convener:Akira Usui(Marine Core Research Center, Kochi University), Yoshio Takahashi(Department of Earth and Planetary Science, Graduate School of Science, The University of Tokyo), Katsuhiko Suzuki(国立研究開発法人海洋研究開発機構・海底資源研究開発センター, 共同), Takashi Ito(Faculty of Education, Ibaraki University), Chairperson:Usui Akira, Suzuki Katsuhiko(JAMSTEC), Takahashi Yoshio(東京大学)

Marine manganese deposits include nodules and crusts of massive iron-manganese oxide aggregates associated with useful metals. The deposits are known as potential resources of cobalt, copper, nickel, rare earth elements, platinum, and tellurium. However, the controlling parameters on the regional and temporal variations in chemical and mineralogical composition have not been clarified yet. In this session, various factors in the growth of manganese oxides, enrichment and circulation of metals, paleoenvironment, and formation age of manganese deposits will be discussed from viewpoints of geology, mineralogy, paleocean sciences, geochemistry, microbiology, and sea floor engineering.

11:30 AM - 11:45 AM
