一、前言关于花岗岩成因的争论,已进行了几个世纪。自从18世纪末 James Hutton 提出花岗岩是由岩浆凝结而成的理论以来,火成论已成为地质学中的主导思想。二十世纪40和50 年代期间,这种理论曾受到变成论(交代说)的挑战。60年代以后,随着科学和实验技术的进步,地壳重熔形成花岗岩的理论已为多数地质学家所接受。1974年,Chappell 和 White 将地壳重熔花岗岩进一步划分为 I 型和 S 型。按他们的定义,I 型花岗岩是由未经过地表
I. Preface The controversy over the genesis of granite has been under way for centuries. Since the late 18th century, James Hutton proposed granite was formed by the magma condensation theory, fire theory has become the dominant idea in geology. During the forties and the forties of the twentieth century, such a theory was challenged to become discourse (argumentation). Since the 1960s, the theory of crustal remelting to form granite has been accepted by most geologists as scientific and experimental techniques advance. In 1974, Chappell and White divided the crust remelted granites further into type I and type S. According to their definition, type I granite is not through the surface
