Taking Bendong and Xiqiu granitic bodies as an example, the thesis expounds geochemical characteristics of mantle-derived type granitoids in Sourthern China in REE and trace elements as follows: lower ∑REE, obvious fractionation of LREE and HREE, negative anomaly of Eu, relative higher ∑LREE/∑HREE,〓 and 〓 ratioes, rich in transitional elements and poor in large-ion lithophile and immobile elements compared with acidite means by Vinogradov. Original mantle-normalized distribution pattern of incompatible elements is one kind of rich -in-strongly incompatible elements type with enrich of K and loss of Sr, P, Ti and trace element association makes a feature of siderophile and chalcophile elements. The tectonomagmatic discriminating shows that mantle -derived granitoids in Southern China belong to orogenic granitoids formed in island arc/marginal sea basin system.
