摘　　要：对架子台沟一带1:50 000化探异常检查中,地表发现有铅锌矿化显示,经对激电测深异常深部钻探验证发现有低品位锌矿(化)体。通过系统采集0号勘探线上的2个钻孔中岩石、矿石样品,进行原生晕特征研究分析表明:矿体近矿元素为Ag、Pb、Zn、Cd,尾矿元素为W、Sn、Bi;轴向分带序列由上至下为:Pb-Au-Ag-Mo-Bi-Sn-Cu-Cd-W-Zn。对成矿元素与相关金属元素进行聚类分析、因子分析,并结合激电测深结果,认为在矿体的侧部、深部仍可能有盲矿体。Some lead-zinc mineralization had been found during the test of 1：50000 geochemical exploration, and the deep drilling verification for electrical sounding abnormity validated the existence of low grade zinc body. We also found that the sub-ore elements were Ag、Pb、Zn、Cd,tailing lements were W、Sn、Bi;and the axial zoning sequence were Pb-Au-Ag-Mo-Bi-Sn-Cu-Cd-W-Zn from top to bottom, by collecting the rocks and samples from No.0 exploration line. The result of cluster analysis and factor analysis on ore-forming element and some metal element shows that there are maybe some more blind orebodies at both side and deep side of the orebody.
