Richard Gunter Bismuth Tellurides in British Columbia
Bismuth tellurides are a suite of complex, layered, phases that occur in the lower temperature portions of quartz veins and massive sulphides that often have a significant enrichment in Au. The geology of the surrounding rock package has a relatively minor influence on the presence or absence of bismuth telluride minerals.
