地质、地球化学和地球物理的综合分析表明,以赣东北断裂带、东乡—江山—绍兴断裂带和宁波—嵊泗断裂带围限的地区是一外来地体,其形成的构造环境与边缘海相当。晋宁期,该地体与扬子大陆边缘九岭区发生碰撞拼贴造山作用,相伴形成了一系列的碰撞造山构造。这一事件控制了九岭山和怀玉山及其邻区中元古—晚元古代的大地构造及其演化。
The comprehensive analysis of geology, geochemistry and geophysics shows that the area surrounded by the northeastern Jiangxi fault zone, the Dongxiang-Jiangshan-Shaoxing fault zone and the Ningbo-Shengsi fault zone is an alien landform, and the tectonic environment formed by it is comparable with the marginal sea . During the Jinning period, collision and collage-orogeny occurred between the terrain and the Jiuling area on the margin of the Yangtze continental China, forming a series of collision orogeny structures. This event controlled the geotectonic and evolution of the Middle Proterozoic-Late Proterozoic in Jiuling and Huaiyushan and their adjacent areas.
