贵州省的 Tianqiao Pb-Zn 矿石存款，中国，位于 Sichuan-Yunnan-Guizhou Pb-Zn-Ag 多金属性的矿化作用区域的中东，它在这个区域的 Pb-Zn 矿石存款是代表性的。它由三主要 orebodies 组成，储备是其 Pb+Zn 超过 20 万吨。这份报纸分析硫这些 orebodies 的同位素的作文。数据表演矿石矿物质(方铅矿，闪锌矿，黄铁矿) 在这些， orebodies 在重硫被充实与在 8.35 和 14.44 之间变化的 34SV-CDT 值，即黄铁矿的 34SV-CDT 值在 12.81 和 14.44 之间，吝啬的值是 13.40；闪锌矿的 34SV-CDT 价值是从 10.87 ～ 14.00 的范围，吝啬的价值是 12.53；方铅矿的 34SV-CDT 价值是从 8.35 ～ 9.83 的范围，吝啬的价值是 8.84，并且他们有 34Spyrite 的特征 > 34Ssphalerite > 34Sgalena，它显示在形成矿石的液体的硫同位素到达了平衡。沉积物的 34SV-CDT 价值在矿石地(15 ) 从不同年龄的碳酸盐阶层硫酸盐接近那些，它建议在形成矿石的液体的硫应该从沉积阶层从硫酸盐的 thermo 化学的硫酸盐减小被导出。

英文摘要：

The Tianqiao Pb-Zn ore deposit of Guizhou Province, China, is located in the mid-east of the Sichuan-Yunnan-Guizhou Pb-Zn-Ag multi-metallic mineralization area, which is representative of the Pb-Zn ore de-posits in this area. It consists of three main orebodies, whose Pb＋Zn reserves are more than 0.2 million ton. This paper analyzes the sulfur isotopic composition of these orebodies. The data show that the ore minerals （galena, sphalerite, pyrite） in these orebodies are enriched in heavy sulfur, with δ^34V-CDT values varying between 8.35‰ and 14.44‰, i.e. the δ^34V-CDT values of pyrite are between 12.81‰ and 14.44‰, the mean value is 13.40‰; the δ^34V-CDT values of sphalerite are range from 10.87‰ to 14.00‰, the mean value is 12.53‰; the δ^34V-CDT values of galena are range from 8.35‰ to 9.83‰, the mean value is 8.84‰, and they have the feature of δ^34pyrite〉δ^34sphalerite〉δ^34galena, which indicates the sulfur isotope in ore-forming fluids has attained equilibrium. The δ^34 V-CDT values of the deposit are close to those of sulfates from carbonate strata of different ages in the ore-field （15‰）, which suggests that the sulfur in the ore-forming fluids should be derived from the thermo-chemical sulfate reduction of sulfates from the sedimentary strata.
