Rare earth mud
Origin: Minamitorishima region (depth: 5,000m or deeper)
This specimen was collected during the cruise "KM19-E02C" of the deep-sea research vessel Kaimei (February 17–27, 2019). JAMSTEC successfully collected a large amount of rare earth mud from the deep seabed using the Power Grab device mounted on the Kaimei.
This sediment contains a high concentration of rare earth elements, which are indispensable for high-tech industries.
Please also see the rare earth elements (Scandium (Sc), Yttrium (Y), and Lanthanum (La)) displayed in the third-floor exhibit "From Basics of Elements and Minerals to Advanced Materials."
