| 摘 要： | 西藏甲马－驱龙矿集区长约124km,宽69km，位于冈底斯陆缘火山－岩浆弧（中－晚侏罗－古近系）的中东部。通过最近的地质调查、矿床勘查和研究，发现冈底斯陆缘火山－岩浆弧带内存在多个矿集区，其中甲马－驱龙矿集区是该弧内一个重要铜多金属矿集区之一。该矿集区的矿床以正在开发的大型甲马铜多金属矿床为代表，还发现了驱龙南、驱龙北、底日玛、松多雄、拉抗俄和象背山等一批非常有潜力的矿床和矿（化）点。它们的矿化类型独特，成因类型多样，是冈底斯陆缘火山－岩浆弧演化过程不同阶段的产物。这些不同类型的矿床集中在一定的区域，已初步显示并成为冈底斯陆缘火山－岩浆弧带内极具成矿潜力、并有一定成矿远景的重要矿集区。相信通过今后进一步工作，该矿集区有望成为中国西部又一个有色金属矿产资源基地。 |

| Abstract: | The Jiama-Qulong ore concentration area,Tibet,124km long and69km wide,is located in the east-central part of the Mid-Late Jurassic-Paleogene Gangdise continental-margin volcanic-magma arc.Through recent geological survey,mineral exploration and ore deposit study,the authors found several ore concentration areas in the Gangdise continental-margin volcanic-magma arc,of which the Jiama-Qulong ore concentration area is one of the important copper polymetallic ore concentration areas in the arc.The deposits of this area are represented by the large Jiama-Qulong copper polymetallic ore deposit which is being ex ploited.In addition,they also found a number of very promising deposits and mineralization oc-currences such as Oulong South,Oulong North,Dirima ,Songduoxiong,Lakang'e and Xiangbeis han.They are characterized by unique mineralization types and a variety of genetic types,suggesting that they are products of different stages of evolution of the Gangdise continental-margin volcanic-magma arc.These dif ferent types of deposit are concentrated in a certain areal extent and have primarily shown and formed an important ore concentration area with great ore potential and a certain ore prospect in the Gangdise continental-margin volcanic-magma arc.The authors believe that through further work this area is expect-ed to become another nonferrous mineral resource base in western China. |
