RELATION BETWEEN THE MEDIUM AND HIGH GRADE METAMORPHIC SERIES AND LOW GRADE METAMORPHIC SERIES IN THE YIHUANG AREA, JIANGXI

摘要: 宜黄地区是赣中南浅变质岩系与武夷中深变质岩系的接触地带，１∶５万区调证实，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，反映了加里东期造山作用的发生→发展→消亡的全过程。Abstract: The Yihuang area lies in the contact zone between the low grade metamorphic series of south central Jiangxi and the medium and high grade metamorphic series of Wuyi. 1∶50 000 regional survey has confirmed that the two metamorphic series have the same protolith formation and deformational history. Their metamorphism is characterized by “gradational transition in space and progressive evolution in time”, implying the entire process of the Caledonian orogeny from generation→development→elimination.
