Based on large amounts of data, this paper makes an analysis of the petrochemistry, ngnferrous metals, trace-element and the REE distribution of the granites in Pingquan district of Xinglong. This study deals mainly with the geochemical characteristics of two types of rocks related to minerahzation in this district, i. e., granite-granite porphyry and granodiorite. The paper points out that the geochemical difference between these two types of rocks is mainly related to the origin of their rockforming materials, beside their different petrological characters.
