摘要
复式岩体和杂岩体是花岗岩类岩体组合的两种基本形式,也是华南花岗岩类岩体的普遍特征之一。所谓"复式岩体"系指不同时代花岗岩类岩体在空间上的共生,组成复式岩体的各部分彼此之间不存在必然的成因联系。所谓"杂岩体"则是指来自同一岩浆房(或岩浆源地)的同源岩浆多次分离、上升和侵入定位所形成的岩体共生组合。研究花岗岩类岩体组合演化的规律,按照明确的涵义,正确地区分复式岩体和杂岩体,具有重要的理论和实际意义。
Compound massif and complex massif are the two basic forms of the association of granitoid. This is also a general character of granitoid geology in south China. 'Compound massif' means a massif that is spatially associated with several granitoid rocks at different ages. Thus the granitoid components are not geneticaly related with each other. The complex massife is meant to a massif that is associated with multiply differentiating ascending and emplacing magma from the same chamber. It is theoretically and pratically important to distinquish the two kinds of massifs.
