一、前言关于花崗岩的成因問題,爭論了将近150余年,至今仍然是一个悬而未决的問題。現在的情况是,火成論与变成諭的势力几乎不相上下,有各具其理、互不相让之势。本文是介紹变成論者牛来正夫用斜长石双晶法研究花崗岩問題的一种新方法。据輿論与实践的反映,此方法有其一定的意义及价值,因此介紹,以供参考。二、斜长石的分类牛来正夫把斜长石的双晶分为三个类型: 1.A 双晶常見于火成岩与变貭岩中,包括鈉长石,肖鈉长石,阿庫林(Acline)等双晶。

First, the preamble On the cause of granite, argued for nearly 150 years, is still an open question. The present situation is that the arguments of fire and the forces that become encyclicals are almost the same, with their own advantages and disadvantages. This article is a new method to introduce the study of granite by the theory of plagioclase by Niu Lai-cheng. According to the reflection of public opinion and practice, this method has its own meaning and value, so it is introduced for reference. Second, the classification of plagioclase Niulaizhengfang plagioclase diphtheria is divided into three types: 1.A bicrystal common in igneous rock and rock, including albite, Xiao albite, Akulin (Acline) and other twin.
