花岗岩类岩石谱系单位的基本特点和有关问题的探讨

本文系统而全面地总结了花岗岩类岩石谱系单位填图的基本特点、原则和方法。提出确立岩浆事件和理顺侵入序次的重要性。并且对侵入作用和火山作用的相互关系；花岗岩类与基性岩类的共生组合；花岗岩类岩石谱系单位填图在时代和类型上的适用范围；均作了探讨，初步提出了处理意见。明确说明花岗岩类岩石谱系单位填图方法的真正核心，是把花岗岩类作为主要地质过程的代表，而不应单纯地把它看作是一种纯化学物质

A STUDY IN THE BASIC FEATURES AND RELATED PROBLEMS OF THE GRANITOID LITHODEMIC UNIT

This paper systematically and comprehensively sums up the basic features,principles and methods of the granitoid lithodemic unit mapping,and points out the importance of establishing the magmatic events and putting the intrusive sequence in order.At the same time,the interrelation between intrusion and volcanism,the three kinds of granitoid and basic rock associations,and the scope of application of granitoid lithodemic unit mapping have also been discussed Finally,the author points out definitely that the core of the granitoid lithodemic unit mapping is to deem the granitoid as the representative of the major geological processes,but not simply as a pure chemical material.
