摘　　要：为了建立有效的地球化学评价指标,对内蒙古哈达门沟金矿床2号脉和13号脉矿石和围岩进行了多元素分析。结果表明,该区金矿化的最佳指示元素为:Au、Te、Ag、Bi、Pb、Se、Mo、Cu、As、Sb,且存在矿化分带现象。稀土元素分析结果表明,深部石英脉矿石的稀土元素含量高,没有明显的Eu异常;而地表含矿石英脉的稀土元素含量低,有较明显的Eu正异常。这些特征可以为该区寻找哈达门沟式金矿提供找矿指标。This article presents the geochemical analysis of the multielements for the wall rocks and ores from the 2nd and 13rd gold veins of Hadamengou gold deposit. The studies show that the best index ele- ments related with gold mineralization are Au, Te, Ag, Bi, Pb, Se, Mo, Cu, As and Sb, and that miner- alization zoning exists in the area. The analysis of rare earth elements indicates that quartz veins containing the ore have no obvious Eu anomaly and quartz veins of surface have relatively obvious Eu anomaly. The rare earth elements of the ore show a increased trend to some extends from shallow to deep areas. These characteristics can provide a prospecting indicator for seeking Hadamenggou gold deposit in this area.
