| 摘 要： | 小西南岔铜金矿床在成因上与燕山早期的火山一深成杂岩关系密切，具有多期、多类型成矿作用叠加的特点，通过对其矿物组构、自然金的矿物学特征、矿石的稀土元素含量及Ag／Au比值、硫、氢氧同位素组成等特征的分析，发现在不同的标高成矿地质特征和地球化学特征等方面有一定规律的变化，形成浅部、中部、深部3个带。

| Abstract: | Xiaoxinancha copper gold deposit is tied tightly in genesis with early Yanshanian volcanic-plutonic complex,with the characteristics of a multi-period and multi-type ore-forming process. Through the analysis of the min- eral assemblage, mineralogical characteristics of native gold, the content of rare earth elements and the ratio of Ag/Au, and S, H and 0 isotopic compositi0n,it was found that the geological and geochemical characteristics changed regularly with the increase of the depth of mineralization,forming three behs with shallow,medium and great depth. |
