| 摘 要： | 碧口岩群是“勉略宁三角区”分布最为广泛的一套浅变质海相火山沉积岩系,属岛弧火山沉积岩建造,各地质体之间均为构造带接触.碧口岩群中Au为富集、强分异、强叠加型,具有明显的分段富集、成带分布的规律性.碧口岩群是区内最重要的金矿矿源层,断裂构造带控制金矿体分布.

| Abstract: | The Bikou Group in the Mianxian-Lueyang-Ningqiang triangular area is the most widely distribution of metamorphic marine volcanic sedimentary rock series, which is attributed into island- arc volcanic-sedimentary formation featured in structural contact between each geological mass. The Bikou Group is rich in gold content with clear differentiation and superimposition, showing the fea- tures of segmentation enrichment and zonation, which is also the most important source bed of gold in this area. The distribution of gold deposits is controlled by fault structures. |
