| 摘 要： | 从干树金矿赋存于怒江构造带高黎贡山岩群变质岩系中,有两个明显的次级矿化带,具多期次成矿作用特点:前期可能为沉积变质赋矿,后期为剪切(构造热液)成矿。晚期在浅部风化淋滤富集。剪切作用形成的金矿是主体。

| Abstract: | The Conggan Au deposit is in the metamorphic rock series of Gaologongshan rock group of Nujiang tectonic zone.The metallogenesis is polyphasic.The early metallogenesis is probably the sedimentary-metamorphic.The later one is the shear metallogenesis(structure hydrothermal).The latest one is the weathering leaching enrichment metallogenesis in the shallow part.And the main Au ore is formed by the shear. |
