个旧老厂锡多金属矿田陡石阶测区断裂构造地球化学异常特征

为对研究区内可能存在的隐伏矿体进行定位预测，指导下一步找矿工作，采用构造地球化学的研究方法，对区内断裂构造地球化学异常特征进行了详细的分析研究。结果表明，本区断裂构造中，主要成矿元素Cu、Pb、Zn、Ag、Sn、Mn的空间浓度分布趋势大致呈现西(北)高东(南)低之势；元素组合异常明显，呈NE向带状展布；主要成矿元素及与成矿相关元素的异常表现出10个浓集中心。这些特点的总结和运用，对指导矿山生产和进一步找矿都具有现实意义。

STRUCTURAL AND GEOCHEMICAL ANOMALY CHARACTERISTICS IN DOUSHIJIE AREA IN THE LAOCHANG TIN POLUMETALLIC ORE FIELD, GEJIU

The research method of structural geochemistry is used to analyze the structural and geochemical anomaly in the deposit in detail in order to carry out a locatiion prediction of the potential concealed orebodies in the target area for the further exploration. The result shows that the distribution of the contents of the major ore elements, Cu, Pb, Zn. Ag, Sn and Mn, tend to be higher in (north)west and lower in (south)east. The element combination anomalies extend to be zoned in northeast direction. There are 10 accumulation centers for the major ore elements and the related ones with mineralization. The summary and application of these characteristics is of realistic significance to guide mine producing and further prospecting in the ore field.
