Abstract

• The tetrahedrite - tennantite series minerals occur extensively in hydrothermal deposits although in minor quantity as compared with other sulfides. Quantitative electron microprobe analysis show that these minerals from the Furtei epithermal gold deposit exhibit compositional variations in which base metals substitute for copper, Sb for As and there is substitution of (Sb, As)3+ for Te4+ ; goldfieldite, tellurian tetrahedrite, tennantite and Te-free tetrahedrite coexist in a polymetallic assemblage highly enriched in telluride minerals. The association of hessite, stützite, sylvanite, petzite, coloradoite, altaite, with native tellurium indicates direct magmatic inputs to the mineralizing solutions: a transition of this zoned magmatic hydrothermal system from porphyry to high sulfidation epithermal mineralization environments is envisaged. Sulfidation states of telluride bearing ore fluids fluctuated between IS and HS conditions within the same mineralization, with telluride minerals and sulfosalts related to both HS and IS assemblages. On the basis of available chemical data on tennantite-tetrahedrite series minerals and the telluride-rich parts of drillcore samples, the relationship between mineral assemblages and sulfidation states is assessed as well as evolution of ore solutions outlined.
