| 中文摘要: |
| 云南广南底圩金矿位于我国滇、黔、桂贵金属成矿带上,矿区总体构造为一背斜,矿体位于背斜核部,金矿床除受地层层位、岩性控制外,还明显受断裂构造的制约和褶皱构造控制。文章结合物化探特征、蚀变及矿化特征,分析了矿床成因,推测可能是火山沉积岩先经过热液改造,后经地表风化淋漓后富集而成的微细粒浸染型金矿床。 |
| 英文摘要: |
| Dixu gold ore deposit, in Guangnan County, Yunnan Province, is located at the gold metallogenic belt of Yunnan, Guizhou and Guangxi. The orebody is located at the core of anticline which is the structural background of whole mine area. The mineral deposit is obviously restricted by rupture structure and controlled by fold structure as well as stratum and lithology. In this article, authors combined its geophysical and geochemical features, features of alteration and mineralization, analyzed the genesis of ore deposit and deduced that the Carlin-type gold mine might result from the volcanic sedimentary rock suffered hydrothermal alteration and enrichment during surface weathering and leaching in this area. |
