“…Other ore minerals are much less abundant; the Bi minerals should be noted among them (Stepanov et al, 1980;Stepanov and Gvozdev, 1987;Gvozdev and Tsepin, 2005). These are bismuthinite-bismuth (with sulfotellurides) and galena-sulfobismuthite assemblages largely related to quartz-sericite metaso matic rocks.…”

“…5). Mineralogy of gold has been described in detail by Stepanov and Gvozdev (1987), Gvozdev and Tsepin (2005), and other authors. According to the published data, free native gold, electrum, and other gold minerals occur in sulfides and quartz, as well as gold finely dispersed in sulfides.…”

“…Stepanov (1977) stated that the most dis tal (flank) sites of the deposit are enriched in sphaler ite. A wide set of sulfosalts, tellurides, and gold miner als are associated with sulfides (Gvozdev and Tsepin, 2005). Stepanov (1977) showed a gradual decrease in homogenization temperature of fluid inclusions in the series scheelite-quartz ore (370-285°С, occasionally 420-400°С) -schellite-arsenopyrite ore (310-270°С, rarely 340-330°C and 250°C) -spheelitechalcopyrite-pyrrhotite ore (310-240°C) -sphaler ite-pyrrhotite ore (240-180°С).…”

“…Native bismuth is widely distributed in various deposits, e.g., W-Sn deposits [7,16,27,28], Pb-Zn deposits [29][30][31], and Au deposits [4,[32][33][34][35][36]. On the other hand, native Sb is less common and occurs mostly in Au-Sb or Au deposits [37][38][39][40], and in trace amounts in Pb-Zn deposits [41,42] and Sn-polymetallic deposits [43].…”

Sb-Bi Alloys and Ag-Cu-Pb-Sb-Bi Sulphosalts in the Jialong Cu-Sn Deposit in North Guangxi, South China

Abstract:Although native bismuth is a relatively common mineral, native antimony is less abundant, and Sb-Bi alloys are relatively rare phases in Nature. Sb-Bi alloys and Ag-Cu-Pb-Sb-Bi sulphosalts have been discovered in the Jialong vein-type Cu-Sn deposit in North Guangxi, South China. The Jialong deposit is hosted by schist within the contact zone of a Neoproterozoic granite. Four stages of ore formation are recognised, with the Sb-Bi alloy-and sulphosalt-bearing assemblage formed during the third stage. Sulphosalts include Pb-Bi-Ag sulphosalts (pavonite), Sb-Bi sulphosalts (tintinaite, terrywallaceite), and Sb sulphosalt (ullmanite, freibergite, bournonite). Grains of Sb-Bi alloy measure 2-20 µm in diameter, show rounded margins and occur together with galena along the edges or internal fissures of sulphosalts. The Sb-Bi alloys do not coexist with bismuthinite, BiS (an unnamed mineral), or with native bismuth. Two phases of Sb-Bi alloys are identified based on back-scattered electron image observations and electron microprobe analysis. The textural and thermodynamic relationships indicate that Phase I was formed before Phase II. Phase I contains high Sb (69.15-80.12 wt %) and lower Bi (18.01-27.85 wt %), while Phase II contains low Sb (0.89-25.24 wt %) and high . Cooling in the range of 270-400 • C and decreasing sulphur fugacity promote precipitation of Sb-Bi alloys and sulphosalts during the late stage of incursion of Sb-and Bi-bearing magmatic hydrothermal fluids.
