Huangzhulin area is located in the southern Ailaoshan metallogenic belt of Yunnan Province, and lies in southwest Yangjiazhai. The lower Permian sandstone, slate and quartz sandstone are main exposed strata. Through soil geochemical profile measurement, a gold anomaly was delineated in Huangzhulin area. The abnormal area has obvious concentration, continuous distribution of high value points, and obvious three-stage zoning. The anomaly is a good composite anomaly with the association of Au-As-Sb-Ag-Mo-Hg and Cu-Pb-Zn. Through the analysis of primary halos of rock samples from Gaojingchao Group, the authors detected the geochemical characteristics of the front halo and near-ore halo of the ductile shear zone type of gold deposit, which has the middle and deep prospecting potential. Based on the geological, mineral resources and geochemical information, the authors present an ore-prospecting model for ductile shear zone type gold and polymetallic deposits in this area.
