摘　　要：研究区位于秦祁昆造山系东昆仑弧盆系之东昆仑北坡复合岩浆弧带,出露地层为古元古代金水口岩群(Pt 1 J),以北东向断裂为主,断裂活动为成矿提供了有利的导矿和容矿空间,岩浆岩主要为中酸性侵入岩,呈岩基状大面积产出。铜钼矿化体属斑岩型成矿系统,构造、脉体、蚀变等找矿标志明显。研究结果对以后的地质勘查具有重要的参考作用。The study area is located in the composite magmatic arc of the eastern Kunlun Mountains on the eastern Kunlun arc basin of the Qinhuangkun orogenic system.The exposed strata are the Paleoproterozoic Jinshuikou rock group(Pt 1J),which is dominated by NE-trending fault and fault activity is mine provides favorable ore-conducting and ore-containing space.The magmatic rock is mainly composed of large-scale output of medium-acid intrusive rocks.The copper-molybdenum mineralization is a porphyry-type metallogenic system,and the ore-forming indicators such as structure,vein and alteration are obvious.The research results have important reference functions for future geological exploration.
