• Celadonite, a green coloured mica clay mineral, is found in amygdales of altered dolerite at Taiheizan, Akita Prefcture. The specimen gives basal reflections at about 10A and its submultiples, and its crystal structure is identified as a 1M polymorph from powder diffraction data. Although a DTA curve shows a small endothermic peak at about 100℃, the 10A reflection was not affected either by heat treatment or by saturation with organic liquids. An infra-red spectrum is similar to that of a ferric celadonite reported by Farmer and Russell (1963). Chemical composition : SiO_2 50.84% ; TiO_2 trace ; Al_2O_3 5.08% ; Fe_2O_3 19.35% ; FeO 2.28% ; MnO trace ; MgO 6.10% ; CaO trace ; Na_2O 1.24% ; K_2O 8.75% ; H_2O^+ 4.48% ; H_2O^- 0.85% ; total 98.97%.
