- IGSN: IEDRM00HU
- classification: igneous
- physical-form: hand specimen
- quantity (kg): 1.82
- description: This rock is collected by T. Kuritani from Tanetomi lava (Lower lava LL2, top clinker layer) in Rishiri Island, Northern Japan. Geochemical analysis were undertaken by T. Kuritani (Kuritani and Nakamura, 2006: JVGR149, p124-138), except for halogen abundances (by Qiaoyun Wang, PhD study in 2010). The sample was provided by A. Makishima to H. Kitagawa on May 18 in 2012.
