摘　　要：利用遥感图像对华东南地区开展了构造格架解译,通过分析解译构造与已知主要断裂的关系,发现了多条NW和近EW向断裂带。岩石形成温度和综合地质分析表明,跨越扬子与华夏陆块的通道—龙川断裂带和永福—佛岗断裂带是前印支期形成的深大断裂,而华夏陆块内的抚州—福州断裂则是燕山-喜山期形成的浅层断裂。初步研究表明,NW向深大断裂带与NE、NNE向断裂带的交汇部位控制了区内铀矿田的空间定位。Remote sensing image was used to interpret the frame structure, and several NW and near EW strike faults were discovered by contrasting the interpreted structures and the mapping out faults. The forming temperature of the surface rock suggest that the NW strike Tongdao-Longchuan and Yongfu-Fogang faults which pass through Yangzi landmass and Cathaysia landmass are two large scale deep fracture formed before Indo-Chinese period, while the Fuzhoul-Fuzhou structure is a shallow fracture formed after Yanshanian period.The intersect area of deep NW strike fault and NE strike, NNE strike fracture control the metallogenic space of uranium ore-field.
