| 摘 要： | 花山锑金矿床位于皖南东至县境内， 是皖南地区代表性金-多金属矿床之一。 本次工作对花山锑金矿床开展了野外地质、岩相学特征观察以及金属硫化物电子探针分析， 得到以下结论：1） 花山锑金矿床主要成矿阶段可分为毒砂-黄铁矿（PyⅠ）阶段、黄铜矿-黄铁矿 （PyⅡ）阶段和方解石-辉锑矿阶段。 2） 金在不同阶段硫化物中均有赋存， 其矿化伴随整个热液成矿过程， 且以毒砂-PyⅠ阶段和黄铜矿-PyⅡ阶段为主。 毒砂-PyⅠ阶段和黄铜矿-PyⅡ阶段发育金矿化， 无锑矿化， 方解石-辉锑矿阶段发育锑、金共生矿化。 3） 早阶段即毒砂 -PyⅠ阶段和黄铜矿-PyⅡ阶段载金矿物为黄铁矿、毒砂及黄铜矿， 成矿物质来源以地层为 主；晚阶段即方解石-辉锑矿阶段载金矿物为辉锑矿， 成矿物质来源以燕山期岩浆岩为主。 本次工作对东至及皖南地区金矿床的寻找勘探具有重要的指示意义。

| Abstract: | Huashan antimony-gold deposit is located in Dongzhi County, South Anhui Province, which is the biggest Sb-Au deposit in Jiangnan transition zone. Based on the detailed geological, petrographic observation and the electron probe microanalysis of the main metal sulfides, We conclude that: 1） The mineralization stages of Huashan antimony-gold deposit consist of arsenopyrite-pyrite（PyⅠ）stage, chalcopyrite-pyrite（PyⅡ）stage and calcite-stibnite stage. 2） Gold exists in multi-sulfides, which means the gold mineralization occured in the whole ore-forming process. There are gold mineralization but no antimony mineralization in arsenopyrite-Py Ⅰ stage and chalcopyrite-Py Ⅱ stage, and the gold mineralization is coexistence with antimony mineralization in calcite-stibnite stage. 3） The main gold bearing minerals is PyⅠ, arsenopyrite, chalcopyrite and stibnite, and the metallogenic materials of the earlier stage mineralization（arsenopyrite-PyⅠ stage and chalcopyrite-pyrite（PyⅡ）are mainly from strata, and later stage’s（calcite-stibnite stage）metallogenic materials are mainly from Yanshanian magma. |
