南岭是一条复杂的构造-岩浆活动带，也是我国重要的铀多金属成矿带。作者在前人丰硕研究成果的基础上，通过地层清理及断代划分，岩性、岩相古地理研究，岩石的年代学及地球化学研究，重磁资料的深层次处理和遥感深层次信息的提取，得出了如下认识：（1）三南-寻乌断裂是一条从早震旦至现代长期活动的东西向深断裂带；（2）南岭地区地壳经历3次不同规模的南北向开合活动；（3）安远-寻乌地区为一大型热隆伸展构造；（4）初步认为该区具备形成富大铀矿的条件。%Nanling is a complicated tectonomagmatic belt. It is also an important uranium-polymetallic metallogenic belt. On the basis of the research achievements of previous researchers, through the detailed stratigraphyic, lithologic, litho-paleogeographic, geochronologic and geochemical studies and the processing of gravimetric and magnetic data, as well as the information extraction of remote sensing data, the authors come to the following conclusions:(1)The Sannan-Xunwu fault is a long-lived(from the Early Sinian to recent time)EW-trending fau(2)The earth crust in Nanling experienced three time opening-closing with different scales;(3)The Anyuan-Xunwu area is a large thermo-upwelling extensional structure;(4)The above area is considered to be favourable for the formation of rich-large uranium deposit.
