国内外对花岗岩类的研究,历史悠久且卓有成效。近十余年来人们广泛地开展了对花岗岩类的新研究,故其成果又有新的发展。以对花岗岩类的成因观点而论,至少有五种以上,即岩浆说或称岩浆分异说,也是传统的经典说,还有重熔说或断裂重熔说,花岗岩化说,沉积说以及火山说等等。而对于花岗岩类的各种划分方案,更是目不暇接,其中已为广大地质工作者所熟知的,举其要者有:壳源型,幔源型,壳幔源型,S型,I型,A型,磁铁矿型和钛铁矿型等等。 The research on granite at home and abroad has a long history and fruitful results. In recent ten years, people have carried out extensive research on new types of granite, so its achievements have been further developed. In terms of the genesis of the granites, there are at least five or more magmatic or magmatic differences, as well as the classical classics, remelting or remelting, graniticization, sedimentation, and Volcano and so on. For granite classes of various programs, even more dizzying, which has been well known to the majority of geological workers, to mention its most important are: shell source, mantle source, crust type, S type, I type, A type, magnetite type and ilmenite type and so on.
