摘　　要：根据1∶20000土壤地球化学测量工作成果,对获得的5 444件土壤样品进行Au、Ag、As、Sb、Cu、Pb、Zn、Mo分析测试表明,Au、Ag、Sb、Mo属强分异型,As、Cu、Pb、Zn属均匀型,Pb、Zn、Ag发生明显的畸变,Au、As、Cu、Mo、Sb畸变程度低;R型相关分析表明Pb、Zn相关性较好。结合地层、构造、岩性、单元素土壤地球化学异常特征圈定了6个组合异常,异常总体走向为北东-北东东向,受北东向构造控制,G-HT-20、G-HT-21、G-HT-23、G-HT-24组合异常规模较大,强度较高,成矿地质条件有利,具有较好的找矿潜力。According to the results of＂ 1：20000 soil geochemical survey, the analysis tests of An, Ag, As, Sb, Cu, Pb, Zn, and Mo on the soil samples obtained show that An, Ag, Sb, Mo are of strong differentiation. As, Cu, Pb and Zn are uniform, and the distortion of Pb, Zn and Ag is obvious, and the distortion of An, As, Cu, mo and Sb is low. The correlation analysis of R-type showed that the correlation between Pb and Zn was well. Combining with the characteristics of formation, structure, lithology and single element soil geochemical anomaly, six assemblages are delineated, and the anomaly which is controlled by NE direction structures overall trend is NE-NEE direction. The combination of G-HT-20, G-HT- 21, G-HT-23, G-HT-24 is of large scale, high strength, favorable metallogenic geological conditions and good prospecting potential.
