| 摘 要： | 鹰嘴山金矿床产于北祁连山与阿尔金南缘断裂的交汇部位，与超镁铁岩在空间上有密切的关系。通过对该矿床地质特征研究，确定了该矿床的产出地质背景和矿化特征，并根据地质、稀土元素、稳定同位素以及流体包裹体等进行了成矿物质来源分析，认为矿床成矿物质主要源自超镁铁岩，其成因类型为低温超基性蚀变岩型金矿床，是北祁连山地区又一重要类型的金矿床。

| Abstract: | Yingzuishan gold deposit lies in the intersection point of North Qilian Mts and South Altyn abruption, it is related to the ultramafite nearly in space. By studying the geology of the deposit, ascertained the deposit's geology background and mineralization characteristics, and analysed minerelization material source according to the geology, REE, stable isotopes and fluid inclusion. The authors believe that the mineralization material of the deposit derived from ultramafite chiefly, its genesis type is cryoultrabasic alteration rock type, and it is another important kind of gold deposit in North Qilian Mts. area. |
