江西地处我国东南部,横跨两个一级构造单元,即北部属扬子准地台区和中、南部位于华南褶皱系,大致以萍乡—广丰深断裂为界。具有构造活动强烈、岩浆活动频繁、沉积作用多样、成矿条件优越等特色。地壳成长经历了多旋回、多阶段的构造发展演化,明显的大的地壳运动有:晋宁运动、加里东运动、华力西—印支运动和燕山运动,伴随每次构造运动有不同程度的变质作用产生,并形成了不同类型的变质岩石。区域变质岩石是省内 Located in the southeastern part of China, Jiangxi lies across two first-level tectonic units, namely the northern part of the Yangtze quasi-platform area and the central and southern parts of the South China fold system, roughly bounded by the Pingxiang-Guangfeng deep fault. With strong tectonic activity, magmatic activity is frequent, sedimentary diversity, superior metallogenic conditions and other characteristics. The crustal growth experienced multi-cycles and multi-stage tectonic evolution. The obvious large crustal movements include the Jinning, Caledonian, Variscan-Indosinian and Yanshanian motions with varying degrees of tectonic movement Metamorphism generated, and the formation of different types of metamorphic rocks. Regional metamorphic rocks are the province
