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 metallogenic 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 anomaly areas. Through verification, the authors found a lead-silver mineralization body in No.Ⅰanomaly area. In combination with an analysis of metallogenic geological environment, the authors hold that this area has promising prospecting potential for lead-zinc-silver resources 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.
