中文摘要：
学术界普遍认为花岗岩能够分离和演化,实际上这是不对的,理由是没有野外和镜下观察的证据。岩浆演化的理论是对的,该理论是从研究玄武质岩浆得来的,只适合玄武质岩浆而不适合花岗质岩浆。本文指出,鲍温反应原理不适用于花岗质岩浆。文中呼吁要重视区分幔源岩浆和壳源岩浆,幔源岩浆可以演化,但是,幔源岩浆不可能演化为壳源岩浆,壳源岩浆不可能演化。
英文摘要：
It is commonly accepted that granitoid plutons can be produced by differentiation of granitic magmas.However,field observations of granitic plutons and textural relationship of the rocks fail to support such a viewpoint.The theory of magma differentiation is based on the study of basaltic magmas rather than granitic magmas.Likewise,the Bowen reaction principle is not applicable to the study of granitic magmas.It is crucial to distinguish mantle-derived magmas from crust-derived magmas prior to discussing the differentiation of magmas.It is possible for mantle-derived magmas to experience fractionation but impossible for crust-derived magmas to do so.
