中文摘要:
      通过对北山南带二段井铅多金属矿开展1 ∶ 1万土壤地球化学测量,结合成矿地质条件进行了土壤地球化学找矿研究。得出以下几点认识:1)矿区土壤中Au、Pb富集系数和变异系数大,成矿潜力好;2)相关分析、因子分析表明Ag、Zn,As、W、Mo,分别代表了中低温成矿作用,可作为Au、Pb的间接找矿标志;3)圈定了7个综合异常,在HT4号异常区中圈定1条金铅矿体,认为该异常区找矿前景很好,是寻找热液型矿床的有利地区,为下一步找矿工作重点靶区。
英文摘要:
      On the basis of 1 ∶ 10000 soil through geochemical survey and its metallogenic geochemical lead polymetallic deposit in the Erduanjing of Subei County, the study on soil geochemical prospecting is carried out. The concentrations of elements such as Au and Pb in the rocks from the ore field are high with the variable coefficients of variation,showing the polymetallic ore prospect in the area. Based on the cluster analysis and factor analysis, Ag, Zn, As, W and Mo individually represented medium and low temperature ture mineralization and can be regarded as indicator elements for ore prospecting. In addition, seven comprehensive anomalies and one Pb bodies have been circled in HT4 anomaly zones, which show good prospecting potential and point out favorable hydrothermal ore-forming region. These work have laid a foundation for the prospecting targets.
