| 摘 要： | 简述云南中西部地壳岩石圈演化历史过程中，中－新生代形成的楚雄盆地与哀牢山造山带两个重要地质单元，在空间上相互依存、在物质上相互转化的特点，分析盆（地）－山（脉）过渡区域主要构造特征，讨论此类构造地段作为构造动力、构造－流体活跃区对矿产资源形成的影响：一是形成与走滑断裂－岩浆活动有关的铜（钼）、金矿床；二是在褶皱－冲断系统，导致铅锌、铜等大宗金属和金、银的巨量堆积。最后强调，盆（地）－山（脉）过渡区域研究在指导新一轮成矿预测评价中的重要现实意义。 |
| 关 键 词： | 盆－山过渡区 成矿类型 中新生代 云南 造山带 楚雄盆地 断陷盆地 |

| Abstract: | Two units, i e , Meszoic-Cenozoic sedimentary basins and orogenic belts were formed during the evolution of the crustal lithosphere of central-western Yunnan. They are each other correlative in time-space and transformed in materials. In this paper, we have an analyse of the main structural characteristics of the transitional area between them and a discussion about the metallogenic effects of this area as an active region of tectonic dynamic and fluid. The metallogenesis can be divided into two types, i e , the Cu(Mo) and Au deposits correlated with strike-slip faulting-magmatism and the magnitude accumulation of a lot of metals, such as Pb, Zn, Cu, Ag and Au resulted from folding-thrusting system. And we believe the study on the transitional area is very important as a guidance to the new metallogenetic prognosis and evaluation. |
