The first roquesite in Japan found in a magnetite-bearing massive chalcopyrite ore from the subvolcanic ore deposits of the Akenobe mine, Hyogo prefecture was determined by electron microprobe analysis giving Cu, 24.9; Fe, 1.8; Mn, 0.2; Zn, 0.1; In, 46.3; S, 25.7; total, 99.0%, and was studied under the ore microscope. Mineral assemblage with this specimen was found to be different from that of the original French roquesite, which may be due to the special condition of its formation, or possibly a lower Eh condition. Occurrence of some indium minerals in Japanese subvolcanic ore deposits suggests the presence of an ‘indium ore province’.
