| 中文摘要:文章总结了云南宝兴厂金矿区地质特征，划分了成矿期和成矿阶段，通过对硫、铅、氢氧同位素特征的研究，认为下奥陶统向阳组第四岩性段的碎屑岩为金成矿的矿源层。多期次的构造_岩浆活动，形成了该区多期次、多阶段、多样式、多矿种的矿床组合类型。矿床类型主要有：斑岩型、石英脉型、构造蚀变岩型、红土型等。该金矿的形成在时间、空间上与喜马拉雅期的富碱斑岩密切相关。 |

| Abstract:Located in the north of the Ailaoshan ore_forming belt, the Baoxinchang gold deposit has its unique geotectonic location that has caused complex metallogenic geological conditions and frequent structural and magmatic activities. The formation of the gold deposit is closely related to Himalayan alkali_rich porphyry both in time and in space. This paper has summed up geological characteristics of this area and made a division of the ore_forming phases and stages. S, Pb, H, O isotope characteristics suggest that clastic rock of 4th lithologic member of Lower Ordovician Xiangyang Group seems to be the source bed of gold mineralization. Multiple phases of structural_magmatic activity has resulted in the complexity of deposit assemblage types in this area characterized by multi_phase, multi_stage, diversity and multiple mineral species. Mineral deposits are mainly of porphyry, quartz_veined, tectonically_altered rock and laterite types. |
