摘　　要：河南省新县付冲一带位于东秦岭—大别山造山带中东部。通过分析研究区内Mo等元素的地球化学分布富集特征,讨论了元素组合特点及相关性;通过对比1∶5万水系沉积物测量Mo异常和1∶1万土壤地球化学测量Mo异常,认为Mo异常重现性好,且伴生Ag,Pb,W等元素组合,具水平分带现象,呈斑岩型钼矿异常特点。研究区内以化探工作成果为重要依据进行工程验证,共发现7条钼矿体,找矿效果较好,且有进一步找矿的潜力。Fuchong area, Xinxian county, Henan province is located in the east Qinling-Dabie orogenic belt. Distribution and concentration pattern of Mo and other elements are analyzed and characteristics of the element combination and their correlation discussed. Mo anomlies of river sediment survey at scale 1： 50000 and soil geochemical survey at scale 1 ： 10000 are compared with high productivity of the anomly. The accompany elements are Ag, Pb, W etc. with horizontal zoning. All this shows anomly characteris- tics of porphyry Mo deposit. According to the geochemical results is laid out prospecting works revealing 7 Mo ore veins and further prospecting potential.
