説明
Colusite, Cu26V2(As, Ge)6S32, containing up to 4.3 wt.% Ge occurs with pyrite, chalcopyrite and bomite in sphalerite-barite-rich ores of the volcanogenic massive sulfide orebody at Hinotani L-1, the Yanahara mine. Electron microprobe analysis reveals that As and V are pentavalent and Ge is tetravalent in the mineral the same as in germanite and renierite, suggesting that the Ge-bearing colusite was precipitated under high fs2 and fo2 conditions. These Ge-bearing minerals sometimes occur in the Kuroko deposits related with felsic volcanism, associated with pyrite, chalcopyrite and bomite as at Hinotani, while practically no Ge-bearing minerals occur in the Besshi-type deposits related with mafic volcanism. It is concluded that the ore solutions responsible for the Hinotani L-1 orebody and possibly for whole orebodies at Yanahara are related with felsic volcanism.
