摘要
花岗岩的成因是地质科学中争议最大的问题之一。70年代提出的著名的Ⅰ型和S型花岗岩分类以及“磁铁矿系列”与“钛铁矿系列”花岗岩分类,所考虑的是成岩物质来源。与“槽—台”构造学说有关的花岗岩成因分类,则朝着构造地质环境分类迈出重要的一步。应用板块构造理论可以科学地解释花岗岩的成因。本文根据板块构造单元将花岗岩的成因类型划分为四大类和九亚类。
The genesis of granites one of the most controversial issues in the geosciences.Some ideas of the genetic types of granites are gradually accepted by scholars.The well known classification which divides granites into the I type and s type and that which divides granites into the magnetite series and ilmenite series consider mainly the source materials forming the granites.The genetic classifications of granites related to the“geosyucline platfrorm”tectonics has advanced an important step towards the classification concerning tectonic scttings. The genesis of granites can be explained scientifically by the theory of the plate tectonics;In this paper the authors divide granites into four genetic types and nine sub types according to the plate toctonic theory。
