| 摘 要： | 克鲁-冲木达矿集区位于西藏南部扎囊-桑日之间,累计估算铜金属资源量达200多万t.文章从"景"、"场"、"相"、"床"金属成矿省等级体制出发,阐述了该矿集区在印-亚陆陆碰撞"陆内汇聚-地壳分层加厚-重力均衡调整"的高原隆升过程中的成矿地质背景,指出区内存在着与碰撞挤压流体迁移汇聚有关的层控铜矿床、碰撞后伸展环境中夕卡岩铜矿床、斑岩型铜矿床3种矿床类型.利用"成矿构造聚敛场"观点分析成矿资源潜力,并指明了找矿方向.

| Abstract: | Kelu - Chongmuda copper and gold belt is located between Zhahang and Sangri counties in the southern Tibet with prospecting copper and gold resources of two million tons and more, Based on tectonic setting, metallotect convergence, metallogeny phases and ore deposit which consist of the metallogeny hierarchy system in a metallogeny province, metallogeny roles in the concentration area with the uplift process of the plateau are expatiated. Three stages like subduction - collision uplift, convergent - compression uplift and isostatie adjust uplift with India - Eurgpe can be divided. Continental collision and then extension in the concentration area had conducted three kinds of ore deposits like stratum copper deposits in the continental collision and subduction, porphyry Cu - Au system and skarn copper deposits in the post - collisional extension. Based on the viewpoint of metallotect converges, ore resource prospect and ore -finding target are indicated. |
