赣东北地区构造概况本区处于九岭东西构造带、华夏系永新-乐平拗褶带和新华夏系怀玉山-武夷山隆起带之复合部位.构造复杂、矿产丰富,尤其是新华夏系构造控制矿床分布的规律极为明显.本区地史上经受了长期的、多次构造运动和不同方式应力的作用,产生了错综复杂的构造形迹.古老的东西向构造组成本区的基底构造,表现为强烈的、南北向水平挤压作用,形成了一系列线型紧密褶皱;较新的
Geological structure in the northeastern Jiangxi Province The area is located in the compound zone of the Jiulong structural belt, the Yongxin-Loping bend fold belt of the Huaxia system, and the Huayu Mountain-Wuyi uplift belt of the Xinhua China series with complex structures and rich mineral resources, especially the structural control of the Xinhuaxia system The distribution of ore deposits is extremely obvious.The history of this area has undergone long-term, multiple tectonic movements and stress stress in different ways, resulting in a complex and complex tectonic trace. The ancient east-west tectonics make up the basement structure of this area, showing strong , North-south horizontal extrusion, forming a series of linear tight folds; newer
