花岗岩成因及构造环境认识

Study on Granites’ Origination and Tectonic Environment

摘要: 在地球中，花岗岩几乎全部产于大陆，是大陆分布最广的岩石之一，是有别于大洋地壳的最主要的物质组成标志。通过研究长期以来地质学者们对花岗岩的研究，取得了一些对花岗岩的认识。其中包括对花岗岩成因的分类。每种类型都对应了不同的地质历史演化。并认识到花岗岩的地壳深熔论是研究其成因的基础所在。在研究花岗岩岩石成因的过程中主要考虑大地构造环境以及源岩对其的影响。最后，深入探讨了花岗岩形成的大地构造背景。

Abstract: In the earth, almost all granite comes from the mainland, which is one of the most widely rock distributions and different from the main composition of oceanic crust. In this paper, by studying the geological scholars for a long time on the study of granite, we got some knowledge of granite. Including the classification of the causes of granite, each type corresponds to the different geologic evolution history. And awareness of the crustal anatexis is the basis of the research the causes in the study of granite rock formation in the process of the main consideration tectonic environment and source rock to its influence. Finally, we further discuss the granite formed by tectonic background.
