摘　　要：本文以豫西伏牛山花岗岩体的遥感地质解译为例，介绍了当代花岗岩地质研究中的同源岩 浆演化和等级体制等学术思想；论述了花岗岩成分演化序列、结构演化序列中各岩浆单元的反 射波谱特征和遥感图像的可解译性；讨论了岩浆单元、侵入体的图形识别和岩浆序列归并、构 造演化的遥感解析方法等问题。In this paper, a new theory about the evolution of the granite magma with the same source and a new method of geological mapping of unit and super-unit system is introduced based on the evolution sequence of mineral composition and texture of granite. which can be recognized with the line of reflected spectrum of diffrent granite units. The methods of the recognizing of the unit of granites, arrangement of the unite and analyzing of the structure of the granite system are also introduced. It is proved that after the renerwing of the geological theory about granite, the advantage of remote sensing on geological mapping of unit-superunit system for granite remains with correct way and the precision of processing and the level of geological investigation can meet recent geological mapping of unit-superunit system.
