The mineral formed as a sublimate directly from fumarolic gas and is associated with a number of other sublimate minerals including cannizzarite, galenobismutite, pyrite and an undefined Fe-K-Si-bearing phase.
Associated sublimate phases are fine-grained pyrite and euhedral cannizzarite and galenobismutite crystals, many of which are coated by small lafossaite crystals.
Locally, associated sulphosalt minerals are: galenobismutite, cosalite, members of the bismuthinite-aikinite series (krupkaite-lindstromite range and gladite-hammarite range), argentian lillianite, Se-free junoite and members of the pavonite homolgous series.
Associated minerals are: bismuthinite (dominant), galenobismutite, cannizzarite and lillianite.
Bismuth is extremely rare, occurring as microscopic grains in galena associated with barite veins in the primary belt, and very rarely associated with galenobismutite (Nagy and Dobosi, private communications).
Galenobismutite occurs as a rare accessory sulfide mineral in the Nikolaevskiy and First Sovietskiy mines.
