内蒙古额济纳旗道噶地区矿化类型为石英脉型，见含 Au石英脉出露。通过对该地区进行土壤地球化学测量工作，在统计研究区各地层Cu、Ag、Au、Pb、Zn、Sb、Mo、Ni、Co、W、As、Sb等微量元素含量基础上，应用聚类分析方法分析元素间相关关系。在研究区圈定出61处单元素异常区，其中 Au元素异常8处。根据地球化学异常分类规范，综合考虑地球化学异常的规模、形态、异常的强度、分带性、异常元素的组合及异常区成矿地质条件和地球化学条件，在单元素异常的基础上圈定出乙类综合异常区2个(Ⅰ号、Ⅱ号综合异常区)，丙类综合异常区1个(Ⅲ号综合异常区)。在对研究区地质特征及土壤地球化学特征的基础上圈定出3个找矿靶区，并进行地表工程验证，为进一步找矿工作提供有利依据。

Daoga area in Ej inaqi county of Inner Mongolia is a quartz-vein mineralization where gold-bearing quartz vein outcrops. The soil geochemistry measurement of study area was conducted in this paper. Based on statistics of the trace element contents of study area formations,we analyzed elemental correlation by cluster analysis.As a result,6 1 multi-element anomaly areas were found,and among them there were 8 abnormal areas of Au.The soil geochemical characteristics and abnormal characteristics were mainly summarized according to the general classification of geochemical anomalies.Considering the scale of geochemical anomalies, morphology,abnormal strength,zoning,abnormal element combination,ore-forming geological anomalies and geochemical conditions,we found out two Type B comprehensive abnormal areas (I and II)and one Type C comprehensive abnormal area (III),on the basis of the single element anomalies.After combining with the geological characteristics and geochemical characteristics of soils,we marked out 3 prospecting target areas,and conducted surface engineering verification,which would provide a favorable basis for further prospecting work.
