| Zusammenfassung: | Carrollite was identified from the ores of the cupriferous pyrite deposit of the Shirataki mine. It occurs closely associated with chalcopyrite and. pyrite. Electron microprobe analysis showed the composition to be very close to Co2CuS4. The mineral is believed to be formed by reaction between chalcopyrite and cobalt which was expelled from pyrite during intense metamorphism. This is the second occurrence of carrollite in Japan. |
