摘　　要：利用遥感图像对华东南地区开展了区域断裂构造解译,发现了3条新断裂,分别是近东西向的醴陵-龙泉断裂,北西西向通道-龙川断裂和永福-佛岗断裂。笔者前期研究表明这3条断裂对地表岩石和铀矿田的分布均有明显的控制作用,属大型断裂。通过布格重力异常和磁异常进一步分析,发现通道-龙川断裂和永福-佛岗断裂具有明显的重力异常和磁异常,深部断裂特征明显,认为应归属深大断裂;而醴陵-龙泉断裂只是中段具有磁异常反应,是否为深大断裂有待进一步研究。Remote sensing image was used to interpret the frame structure in Southeastern China,and three large faults was newly identified: there are EW strike Liling-longquan fault;NWW Strike Tongdao-Longchuan fault and Yongfu-Fogang fault. The authors verified that the three faults are large fault and has significantly effects on the distribution of rock outcrop and uranium ore-filed. Gravity and magnetic data were used to study the deep extension feature of the three faults. It was found that Tongdao-Longchuan and Yongfu-Fogang faults produced wholly significant gravity and magnetic anomalies which respondent to the deep fault obvious,while Liling-Longquan fault only showed local anomaly in its middle segment. Therefore,Tongdao-Longchuan and Yongfu-Fogang fauls were regarded as large-deep faults,the deep feature of Liling-Longquan fault need more study to validate.
