| 中文摘要: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 dissem inated gold deposit, the authors analyzed its genesis through an integrated stud y 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 ep och, that its ore_forming materials came from surrounding strata, and that magma tic activities were involved in the ore_forming process. It is a mixed hydrother mal gold deposit related to magmatic activities. |
