摘　　要：滇黔桂地区分布着众多大中型Hg、Sb、Au矿床。通过对碳、氢、氧、硫等同位素的分析表明：大厂锑矿的硫来自地幔，木利、马雄锑矿的硫主要来自海水硫酸盐。各金矿的硫主要来自围岩，但碳大部分来自围岩。氢氧同位素数据表明，本区锑、金、汞等矿床的成矿流体来源相似，其主要来源为与围岩进行了氢氧同位素交换的大气降水。There are many large- and middle-scale Hg, Sb, Au and As deposits. Based on the data on C, H, O and S isotopes, it is confirmed that the sulfur in the Dachang Sb deposit and the Muli and Maxiong Sb deposits and gold deposits was derived from the mantle, seawater sulfates and country rocks, respectively. And in the gold deposits, most of the carbon comes from the country rocks. The origins of ore-forming fluids of Hg,Sb and Au deposits are similar, mostly derived from meteoric water which had been exchanged in hydrogen and oxygen isotopes with the country rocks.
