Geochemical rock survey section from Guxian Reservoir to Quanbao Mountain is located in the Shagou-Longmendian Ag polymetallic ore concentration area of western Henan Province. The obvious anomalies of Au, Ag, Cr, Co, Cu and Pb were found about 6.0km to 10.0km in length along the section. The results obtained by the authors are important in search for concealed igneous bodies and ore bodies in the depth under 6.0~10.0 km in geochemical rock survey section, and also of great significance in finding new type deposits, such as pegmatite-type Au deposits and porphyry-type deposits in the Shagou-Longmendian Ag polymetallic ore concentration area.
