摘　　要：河南洛宁南岭地区位于华北克拉通南缘与秦岭造山带结合部位之北侧,属熊耳山铅锌金银多金属成矿带之北亚带。通过对该区开展1∶1万土壤地球化学测量,分析元素地球化学特征、单元素异常特征、异常赋存的地质环境等,圈定了4个综合异常区并进行查证,在Ⅰ号异常区寻找到一条铅银矿化体。结合成矿地质条件分析,认为该区找矿前景很好,是寻找中低温热液充填交代型铅锌银多金属矿的有利地区。对该区继续开展工作,可望获得突破性进展。Located in the juncture between the Qinling orogenic belt and the southern margin of the North China Craton, the Nanling area in Luoning County of Henan Province belongs to the northern subzone of the Xiong＇ershan lead-zinc-gold-silver polymetallic metal-logenic belt. Based on 1 ∶ 10 000 soil geochemical survey, the authors analyzed the element geochemical characteristics, single-element anomalies and geological environment for the occurrence of anomalies in the Nanling area, and finally delineated four comprehensive a-nomaly areas. Through verification, the authors found a lead-silver mineralization body in No.Ⅰanomaly area. In combination with an a-nalysis of metallogenic geological environment, the authors hold that this area has promising prospecting potential for lead-zinc-silver re-sources and is a favorable area in search for epithermal filling metasomatic lead-zinc-silver polymetallic deposits. Continual work in the area is likely to get a breakthrough.
