宜黄地区是赣中南浅变质岩系与武夷中深变质岩系的交接地带，通过１∶５万地质填图已证实，两套变质岩系具有相同的原岩建造和变形历史，其变质作用具“空间上渐变过渡，时间上渐进演化”之特点，较好地反映了加里东造山作用发生→发展→消亡的全过程
The Yixian area is the transition zone between the middle-Ganjiang-Middle-shallow metamorphic rock series and the Wuyi middle-deep metamorphic rock series. It has been confirmed through 1: 50000 geological mapping that the two sets of metamorphic rocks have the same history of original rock formation and deformation, and their metamorphism With the characteristics of “gradual transition in space and gradual evolution in time”, the whole process of occurrence of Caledonian orogeny → development → demise is well reflected
