| 摘 要： | 中国主要类型锑矿床的硫同位素组成范围变化很大，锑矿床中各种矿物（辉锑矿、黄铁矿、闪锌矿、雄黄、方铅矿、重晶石、毒砂、辰砂、脆硫锑铅矿）的δ３４Ｓ值从－３２．７‰变化到＋３４．８‰，极差值高达６７．５‰。各类锑矿床中矿物的硫同位素组成变化各异，说明锑矿床成因较复杂，硫的来源不仅有海水中沉淀的硫酸盐硫，而且还有生物、细菌形式的还原硫和深源硫（岩浆作用、喷流作用等），从而形成不同类型或成因复杂的锑矿床

| Abstract: | The Sulfur isotope compositions of the antimony deposits of main types in China are featured by a great varying range of 34S values. The 34S values of various mineral of the antimony deposits,including stibnite,pyrite,sphalerite,realgar,galena,barite,arsenopyrite,cinnabar,jamesonite,range from-32.7 to 34,the extreme difference amounting up to 67.5. The sulfur compositions are different according to different types,indicating that the antimony deposits have complex genesis and different sources,including not only the sulfur decomposed from sulfate sedimented from the sea water,but also the reduction sulfur in the forms of bio-organisms and bacteria,and deep source sulfur (from magmatism and exhalatism etc.). |
