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’.

A black prismatic kobeitc-like mineral from a granite pegmatite of the Ushio mine in Ômiya town, Kyoto Prefecture and the kobeite from the original locality have been studied. Both the chemical analyses and the X-ray powder patterns of heated materials of the two minerals gave the concordant results. The two minerals contain notable amount of zirconium and after heat treatment give X-ray patterns similar to those of stabilized cubic zirconia. Kobeite will not be a member of the euxenite-polycrase series but may be a distinct mineral species of multiple oxide containing Y, Fe, U, Ti, Zr and Nb as the main components.
