| 摘 要： | 内蒙古阿鲁科尔沁旗蛤蟆石铅银钼多金属矿地处内蒙古大兴安岭成矿带中南段,西拉木伦河断裂以北,工作和研究程度低,通过普-详查工作首次对该矿床有了较为正确、系统的认识。对矿区地质特征、矿体地质特征、矿石地质特征及成矿要素进行了初步分析总结,认为EW向断裂构造为成岩成矿断裂,矿体与EW向展布的沿断裂充填的晚侏罗世次流纹岩时空、成因关系密切,矿体赋存于次火山岩侵入接触构造-硅化蚀变带(次生石英岩化带)中,矿体呈脉状、透镜状EW向分布。通过分析认为矿床成因为次火山热液矿床,与次火山有关的硅化带、次生石英岩化带是该区寻找相似成因矿床的找矿标志。

| Abstract: | The Hamashi Pb-Ag-Mo polymetallic deposit is located in the middle- south segment of the Great Xingan Mountains metallogenic belt and the north of the Xilamulun fault in Inner Mongolia. The degree of work and research of this deposit is very low. General surveys and detailed exploration allow us to have correct and systematic understanding to this deposit. We have summarized the geological features of the mining area, ore bodies and ores, and ore-forming factors of the deposit. The results show that the E-W trending faults are the diagenetic and metallogenic structures in this area, and the ore bodies are related to Jurassic rhyolite, which strikes in E-W direction and fills the faults. The ore bodies occur in the contact structure of volcanic intrusive and silicification zones (secondary quartz rock band), and are distributed in the east-west direction of vein and lens. We concluded that the Hamashi Pb-Ag-Mo polymetallic deposit is a subvolcanic hydrothermal deposit, where silicified zones associated with the sub volcanic and secondary quartz rock band are the marks for searching for the deposits with similar genesis in this area. |
