Abstract Northeastern Yunnan Province is an important region for lead, zinc and silver resources, with quite a few Pb-Zn deposits and mineralized spots. Chejiaping area in Huize is close to the large Pb-Zn mines such as Kuangshanchang and Qilinchang, with great prospecting potentiality. On the basis of detailed geological work, the 1:10000 scale geochemical survey is carried out in the area. The iteration method is adopted to determine the background value and anomaly threshold, with the assemblage of Pb, Zn, As, Cu and Cd as the best indicator. By analysis on the geochemical anomaly shapes, scale and zonation, 3 prospecting targets are delineated, which will provide basis for the searching of blind orebodies in the area.
