对于花岗岩的起源曾经是岩石学家和地球化学学家所关注的一个问题。但是近年来普遍意识到变形作用在大陆地壳中的富硅熔体的分离、运移和就位过程中的本质性作用。已被接受的岩石学模型正越来越受到人们置疑,这是因为这些模型的建立需要岩石和岩浆具有不现实的流变行为,或者是因它们不能满意地解释实际的构造数据或地球物理数据。不考虑构造背景,假定流体是连续的,从动力学考虑表明花岗岩浆活动是以小于０．１Ｍａ时间尺度的一个迅速的、动态的过程,远非地质学上所讲的那种缓慢过程。
The origin of granites was once a matter of concern to petrologists and geochemists. However, in recent years, it has been widely recognized that the deformation plays an essential role in the separation, migration and site-setting of silicon-rich melt in the continental crust. Accepted petrological models are increasingly being questioned because their establishment requires unrealistic rheological behavior of the rock and magma or because they can not satisfactorily explain the actual tectonic or geophysical data . Regardless of the tectonic setting, the fluid is assumed to be continuous, and kinetic considerations suggest that granitic magmatism is a rapid and dynamic process on the time scale of less than 0.1 Ma, far from the slow process of geology.
