两类花岗质岩石的发育概况关于花岗质岩石的成因分类,已有不少介绍.本文所述过渡型花岗岩(大体相当于Ⅰ型或同熔型花岗岩)主要分布于赣北(图1);赣中、赣南分布零星.该类岩体多受深大断裂控制,见于隆拗交接带的旁侧,呈不连续的串珠状线型展布、出露面积为一至数平方公里的筒状岩株或岩墙.岩石类型主要有石英闪长(玢) The developmental classification of two types of granitic rocks There have been many introductions on the genetic classification of granitic rocks.The transitional granites (roughly equivalent to type I or the same type of granites) described in this paper are mainly distributed in northern Jiangxi (Figure 1 ); Jiangxi, southern Jiangxi sporadic distribution.They are mostly controlled by the deep faults, seen in the side of the bend over the junction zone, showing a non-continuous beaded linear distribution, the exposed area of ​​one to several square kilometers Tubular rock or rock wall. The main rock types are quartz dilatometer (玢)
