The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.

形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境，部分岩石具有碰撞期或非造山期花岗岩的某些特征，表明碰撞后阶段既是碰撞造山过程的延续，又是向非造山环境的构造转换时期，因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明，区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔，由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

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.
