Hydrothermal environments

Lindströmite is of hydrothermal origin. Associated minerals include krupkaite, other aikinitebismuthinite series members and bismuth (HOM).


At the Cobalt area, Cobalt-Gowganda region, Timiskaming District, Ontario, Canada, the major ore minerals in the deposit are native silver and skutterudite, with minor chalcopyrite, sphalerite, galena, pyrite and nickeline hosted in systems of calcite veins. Lindströmite is associated with laths of native bismuth and, in some cases, with minor amounts of chalcopyrite in mineralised veins a few mm thick in a graywacke matrix. The mineral textures are consistent with crystallisation at temperatures below the melting point of bismuth (below 270°C) (CM.36.1139-1148).

At the type locality, the Gladhammar mines, Västervik, Kalmar County, Sweden, lindströmite occurs on quartz in crystals 1 cm long and several mm thick (AM 10.157). The type crystal contains a small amount of exsolved krupkaite (CM 15.527-535).
