架子台沟低品位铅锌矿原生晕地球化学特征及深部矿产预测

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。

GEOCHEMICAL CHARACTERISTICS OF PRIMARY HALO OF LOW GRADE LEAD-ZINC AT JIAZITAIGOU

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.
