江西北部前寒武纪地壳可分为南、北两区。在早元古代江西北部尚属大洋优地槽,大别运动使北区基底开始固结,至中元古代演化为边缘海,而南区仍为大洋优地槽。晋宁运动使北区进一步固结上升为陆,南区基底变质褶皱,外海迁至赣南。由于南、北两区地壳演化不同,成矿作用各具特色。
The Precambrian crust in northern Jiangxi can be divided into two zones, south and north. In the Early Proterozoic, the northern part of Jiangxi Province still belonged to the oceanic favorable trough. The Dabie movement started to consolidate the basement of the northern part of the province to the marginal sea in the Middle Proterozoic, while the southern part was still the oceanic favorable trough. Jinning movement to further consolidate the North rose to land, the basement metamorphic fold south, offshore moved to southern Jiangxi. Due to the different crustal evolution in South and North regions, the mineralization has its own characteristics.
