The purpose of this paper is to make prospective assessment for Pt and Pd geochemical megaprovince of Panjiang catchment. Testinq of Pt and Pd contents in various rocks indicate that the crust block in Panjiang catchment is rich in Pt and Pd. The geochemical megaprovince of Pt and Pd is a surface expression of the original geochemical heterogeneity of the earth. It is hoped that some giant deposits of Pt and Pd can be found in this geochemical province.
