    内蒙古额济纳旗珠斯楞海尔罕北矿段锌铅金银铜矿矿床地质特征及其找矿潜力分析

    The Geological Characteristics and Prospecting Potential Analysis of North Zhusilenghaierhan Lead-Zinc-Gold-Silver-Copper Deposit in Ejin Banner,Inner Mongolia

    • 摘要: 内蒙古额济纳旗珠斯楞海尔罕矿区锌、铅、金、银、铜矿赋存于二叠纪花岗闪长岩、花岗斑岩与围岩的内接触带之中,属于中-低温热液矿床。二叠纪花岗闪长岩为矿体的形成提供了热源和物源,北西向的断裂构造则为花岗斑岩的侵入和成矿热液提供了通道。在珠斯楞海尔罕矿区及其邻区,发现类似的二叠纪岩浆活动以及断裂构造。因此,该地区可能发育类似成因的锌、铅、金、银、铜矿,具有良好的成矿潜力。

       

      Abstract: As a meso-and epi-hydrothermal deposit, the North Zhusilenghaierhan zinc-lead-gold-silver-copper deposit occurred in the Permian granodiorite, granite porphyry and the inner contact zone of surrounding rock. In the course of ore bodies formation, the Permian granodiorite provides the hydrothermal fluid and mineralization substances. The northwest-southeast trending faults offered a channel for granite porphyry intrusion and ore-forming hydrothermal fluid. Nearby ZhusilengHai'erhan,we can still find similar Permian igneous activity and faults. So these areas may exist the similar zinc-lead-gold-silver-copper deposit, and have a good mineralization potentiality.
