| 摘 要： | 苦嘎铜矿位于西藏措勤-念青唐古拉成矿带的中段,矿体产在矽卡岩及花岗岩近东西向的构造带中,矿床的形成与永珠蛇绿岩带的形成及演化关系密切。永珠带拉伸阶段形成的日拉组为成矿的主要地层条件,而永珠蛇绿岩带聚敛消亡阶段的构造岩浆活动是该区成矿的必要条件。苦嘎铜矿的发现对藏北以永珠蛇绿岩带为中心的措勤-念青唐古拉成矿带的找矿工作具有一定的指导意义。

| Abstract: | Kuga copper deposit is located in the middle part of mineralization belt from Cuoqin to NianqingTanggula,the orebody exists in structural belt of skarn and granite near east and west in direction,deposit formation had close relation to the formation and evolutionary process of Yongzhu ophiolite belt,main metallogenetic stratum is Rila Formation which formed during Yongzhu ophiolite belt tensile,but metallogenetic necessary condition is teotonic-magmatic activity during convergence and consumed of Yongzhu ophiolite belt in this area.Kuga copper deposit found is of great significance for mineral prospecting work where is round Yongzhu ophiolite belt within mineralization belt from Cuoqin to Nianqing-Tanggula. |
