摘要
本文研究了西坑银矿床的硫、铅、氢、氧稳定同位素．结合矿床地质特征，认为西坑银矿床成矿物质主要来源于地层，成矿热液为演化的大气降水与岩浆水的混合水．
n the basis of analysing the geologycal features of Xikeng Silver deposit,the ore-forming origin is dealt with herein.The emphasis is focused on the study of the stable isotopesof hydrogen,oxygen,sulphur and lead. It is considered that the minerognetic elements stem mainly from.the edments,and the evolutionary precipitated water is the principle minerogenetic byderothrmal fluid.Magmatism becomes the significant power of heating and driving the atomo spheric precipitation.The mineralization style of Xikeng deposit is that of hydrothermal leaching.
