摘　　要：位于内蒙古自治区北山成矿带东南部的月牙山–老硐沟地区发育有月牙山、老硐沟等一系列金多金属矿床。笔者对该区典型金多金属矿床的地质特征和关键控矿因素进行了系统研究,结合各类找矿信息开展综合找矿预测工作。研究表明,区内的典型金多金属矿床多伴生Ag、Pb、Zn等元素,矿体受加里东—华力西期中酸性岩体、北西–北西西向断裂控制,为典型的热液脉型金多金属矿床。高磁异常体、北西–北西西向断裂、Au−Ag−Sb地球化学异常叠加部位为此类矿床的有利找矿地段。笔者采用MRAS软件对各类找矿信息进行综合,共圈定4个找矿靶区,野外查证在其内均发现重要矿化线索,为研究区下一步勘查工作的开展指明了方向。The Yueyashan–Laodonggou area of Inner Mongolia is located in the southeast of Beishan ore belt,where has existed a series of gold polymetallic deposits,such as Yueyashan and Laodonggou gold–polymetallic deposit.Based on the systematically analyzed of the geological characteristics and key ore–controlling factors of typical gold–polymetallic deposits in this area,the comprehensive metallogenic prediction is carried out in this paper.The study shows that the gold in the area is mostly occurs with silver,lead,zinc.The gold orebodies are controlled by Caledonian–Hualixi intermediate acidic rock mass and NW–NWW faults,is a typical hydrothermal vein–type gold–polymetallic deposit.The high magnetic anomalies,NW–NWW faults and superposition sites of Au–Ag–Sb geochemical anomalies are favorable ore–prospecting areas of gold polymetallic deposits.The MRAS software is used to synthesize all kinds of prospecting information,four prospecting targets have been delineated,and high-quality mineralization and alteration were observed in four of them by field verification,which pointed out the direction for the next-stage work in this area.
