| 摘 要： | 文章在系统总结马脑壳微细浸染型金矿床地质特征、成矿时代的基础上。通过稀土元素及氢、氧同位素地球化学研究，分析了矿床成因。结果表明，马脑壳金矿床形成于印支晚期，其成矿物质来自围岩地层，岩浆流体参与了成矿作用，矿床为与岩浆活动有关的混合热液金矿床。

| Abstract: | Based on summarization of geological features of the Manaoke fine_grained disseminated gold deposit, the authors analyzed its genesis through an integrated study of Rb_Sr isochron dating of fluid inclusions in quartz of the main ore_forming stage, geochemistry of rare earth elements and isotopes of hydrogen and oxygen. The results show that the Manaoke gold deposit was formed in Late Indosinian epoch, that its ore_forming materials came from surrounding strata, and that magmatic activities were involved in the ore_forming process. It is a mixed hydrothermal gold deposit related to magmatic activities. |
