| 摘要 | 对滇西两类铜多金属矿床开展了系统的地质地球化事研究，并取得了以下成果：①首次在该铜多金属矿带发现了硅质岩层，并证实是热水喾的产物；②查明矿体的成矿物后来源；③提出了矿床的成因模式，④确定了在该寻找大型超大型号矿体的找矿方向。 |
| 其他摘要 | The author systematically studied geological and geochemical characteristics of the copper polymetallic ore-belt in western Yunnan and acquired the following new knowledge: (1) This is the first time to discover the silicalites in this copper polymetallic ore-belt and to certificate that the silicalites are formed by the hot-water sedimentation. (2) The ore sources are made clear that Cu and Pb come from the mix of the upper earth crust and the upper earth mantle, and the mineralization such as S and C come from the magmatism or the upper mantle. (3) The genetic modes are put forward. (4) The author put forward that it is difficult to form the large-scale copper deposits in the sedimentary rocks of the middle in the ore best, but it is easy to form large and super-large copper polymetallic deposits in the vocanic-sedimentary rocks of the two ends in the orebelt. |
