“…Many researchers (e.g., Hall & Czamanske 1972, Amcoff 1976, Wu & Petersen 1977, Jeppsson 1987, Cabri 1992) have recognized that the silver contents in Ag-bearing ores may be partly or principally accounted for by Ag-bearing minerals, especially argentian tetrahedrite. However, argentian tetrahedrite is rare in the Kangjiawan deposit, particularly in the northern part.…”

The Kangjiawan deposit, in the Shuikoushan district, Hunan Province, China, is a representative hydrothermal Pb-Zn-AgAu deposit in this region. The orebodies consist mainly of pyritic Pb-Zn ores. Silver minerals are associated with Pb-Zn mineralization. Ag-bearing Pb-Zn ores in the deposit are characterized by Ag > Cu > Sb content. Silver occurs mainly as silver minerals, such as minor argentian tetrahedrite, freibergite and abundant polybasite-arsenpolybasite, pearceite and pyrargyriteproustite, and all are hosted in galena. The assemblages of silver minerals found in the major orebodies change from the southern to the northern part, from argentian tetrahedrite + freibergite + pearceite + arsenpolybasite + pyrargyrite-proustite in the south to polybasite-arsenpolybasite + pyrargyrite, and to pyrargyrite in the north.Keywords: silver minerals, tetrahedrite, freibergite, polybasite-arsenpolybasite, pearceite, pyrargyrite-proustite, Kangjiawan PbZn-Ag-Au deposit, Hunan Province, China. SOMMAIRELe gisement de Kangjiawan, situé dans le district de Shuikoushan, province de Hunan, en Chine, est représentatif des gisements hydrothermaux à Pb-Zn-Ag-Au de cette région. Les gisements contiennent surtout un minerai pyritique à Pb-Zn. Des minéraux d'argent sont associés à la minéralisation Pb-Zn. Dans le minerai Pb-Zn contenant de l'argent, la teneur du minerai répond à la relation Ag > Cu > Sb. L'argent se trouve surtout dans les minéraux d'argent, par exemple tétraédrite argentifère et freibergite accessoires, et polybasite-arsenpolybasite, pearceïte et pyrargyrite-proustite plus abondantes, et tous englobées dans la galène. Les assemblages de minéraux d'argent des gisements importants varient du sud vers le nord, de tétraédrite argentifère + freibergite + pearceïte + arsenpolybasite + pyrargyrite-proustite dans le sud à polybasite-arsenpolybasite + pyrargyrite, et à pyrargyrite dans le nord.

“…Later the Idaho Bureau of Mines and Geology, under the supervision of A. L. Anderson (Anderson and others, 1950), studied the ore deposits and evaluated their potential. Hall and Czamanske (1972) studied the mineralogy and traceelement content of the lead-silver deposits that were being mined in 1969 near Bellevue and Hailey. The district was inactive at the time of this isotope study ; thus sampling was limited to dumps and samples collected for the earlier mineralogical study.…”

“…The galena is argentiferous. Czamanske found, by electron microprobe analyses, that slightly less than half of the silver is coupled with antimony in solid solution in the galena; the rest is present in micrometer-size silver-antimony inclusions of five compositions, though principally as diaphorite (Hall and Czamanske, 1972).
