摘    要:通过对华南及其相邻的边缘海域的布格重力异常和磁力数据的处理和分析,利用水平方向导数、小波变换及典型剖面反演的共同结果,在研究区中分辨出方向各异的主要断裂共39条,根据重磁异常特征并结合层析成像结果分析了研究区内断裂的分布与延伸,特别对红河断裂带等重要断裂进行了重点讨论,并探讨了它们的延伸及与周边各地质单元之间的关系。

关 键 词:断裂  地球物理证据  布格重力异常  磁力数据  小波变换  海域

Abstract:South China and adjacent marginal seas region is located in the area where Euro-Asia Plate, Philippine Plate and India Plate meet together. It's an important window to research the formation and evolution about Chinese Continent and marginal seas. In this paper, 39 main faults with different directions in research area are distinguished after processing (horizontal direction derivative, wavelet transform and inversion for special sections) and analysis for gravity and magnetic data of research area. The feature, extension direction of some faults (for example: Red River Fault) and relationship between faults and adjacent geological blocks are discussed according to geophysical anomaly features.
Keywords:South China and Adjacent Marginal Seas  Faults  Geophysical evidence
