这里提出各种斜长岩体,均由安山岩岩浆或玄武岩岩浆在粒变岩的变质条件下,经结晶和分离作用所形成。对于任何一个单独的岩体,其母岩浆的类型可以通过检验伴生岩石类型的垂直层序来确定。
Various types of plagiogranite bodies are proposed here, all of which are formed by the crystallization and separation of andesite or basalt magma under the metamorphic conditions of granulite. For any single rock mass, the type of parent magma can be determined by examining the vertical sequence of associated rock types.
