...Asahiko Sugaki; Hiromi Shima; Arashi Kitakaze Abstract Miharaite, Cu 4 FePbBiS 6 , is a new sulfosalt discovered at the Mihara mine, Okayama Prefecture, Japan. It occurs only as minute (<0.3 mm) grains in bomite, closely associated with chalcopyrite, galena, and wittichenite in bomite-rich skarn...

Iron is tetrahedrally coordinated, with bond distances ranging between 2.30 and 2.37  Å, with an average value of 2.33  Å. Octahedral coordination of iron...

A reopening of the veins during the third stage was accompanied by the precipitation of a sulfide assemblage and native gold. The mineralization is epithermal (230–390°C), and results...

... mainly formed by massive chalcopyrite. Associated with these minerals, a rather unusual suite of ore minerals including miharaite, carrollite, vinciennite, galena, colusite, stromeyerite, arsenopyrite, sphalerite, tetrahedrite, and naumannite (occurring as exsolution-induced blebs in galena) have been...
