| 中文摘要: |
| 众所周知,硫盐矿物的化学通式为:AmBnxp;其中常见的元素为A:Ag、Cu、Pb和少量Sn、Fe;B:As、Sb、Bi;X:S.硫盐矿物是X与B组成较显著的配位多面体,再与A相连接,形成复杂的硫化物,称之为"硫盐".据L. L. Y. Chang[2]统计,已知硫盐矿物按化学组成分有88种之多,其中锑铋硫盐有6种.在我国盛产硫盐矿物的广西大厂锡多金属矿田,经30余年的地勘、矿山开采及大量科研工作的进行.至今,已鉴定有25种硫盐矿物,而且该矿作为重要工业原料的铅、锑主要来自脆硫锑铅矿和硫锑铅矿. |

| Authors have determined seven species of sulfosalts: pyratgyrite, freibergite, bournonite, boulangirite, jamesonite and its variety of bismuth-bearing iamesonite, and garavellite by the reflected light microscope, microprobe, and some X-ray powder photograph and diffraction analyses. The bismuth-bearing Jamesonite is different from the bismurh jamesonite found in Ustasaisk deposit by M.S. Sakharova (1956). The latter two minerals have supplemented the tin-poly metallic deposits. According to the mineralography, chemistry of minerals, the temperatures of the inclusions, and the phase equilibra of the sulfides and sulfcsalts, it was discussed that the sulfosalts in this district are formed in two stages of mineralization (Ⅱ① and Ⅲ) and at two ranges of temperature (about 380° and 200℃). The stage Ⅲ is the major stage of mineraiization. |
