| 摘 要： | 青海省都兰县瑙木浑沟口金矿区位于昆中构造带北侧,区内断裂构造十分发育,金矿成矿条件优越。运用激电中梯测量,基本查明了区内与金成矿有关的断裂构造的分布情况,圈定激电异常2处,并施工探槽工程、硐探工程进行异常查证,证实物探异常为构造破碎带内硫化物富集体引起的,金矿化体与异常峰值对应基本吻合,最终发现了一处隐伏金矿床,说明物探异常在寻找隐伏金矿体的找矿工作中获得了很好的找矿效果。结合构造因素、物探异常及已有成矿事实综合分析,认为该区有较好的找矿前景。

| Abstract: | Goukou gold deposit in Naomuhun area of Dulan county in Qinghai province is located in the north of Kunzhong tectonic belt. The fault structures are well developed in the area and the gold mineralization conditions are favorable. The distribution of fault structures related to gold mineralization in the area has been basically identified by means of IP middle elevator survey. Two IP anomalies have been circled. The geophysical anomalies have been verified by means of trench and tunnel prospecting. It is proved that geophysical anomalies are caused by sulfide enrichment bodies in structural fracture zones, and the corresponding peaks of gold mineralization bodies and anomalies are basically coincide. Finally, a hidden gold deposit has been discovered. It is showed that geophysical anomalies have obtained results in prospecting for hidden gold deposits. Based on comprehensive analysis of structural factors, geophysical anomalies and existing metallogenic facts, it is considered that the area has a good prospecting prospect. |
