摘　　要：广西壮族自治区地处中国东南部大陆边缘活动带,属古生代扬子板块的南缘,东临华夏板块,西邻印支板块,处在三大板块的结合部位.历史上火山运动剧烈,伴随不同时期的火山喷发及侵入作用,形成各种金属矿产,并且明显受到断裂构造的控制.本文根据卫星重力、高程模型(EGM2008),运用小波多尺度分析及水平梯度模量分析对广西地区区域地质特征进行了相关讨论.Guangxi lies in the southern Paleozoic Yangtze plate, located in the continental margin belt of southeastern China at the binding site of the Huxia plate and Indo-China plate. In history, with different periods of volcanic eruptions and intrusions, a variety of metal ores were formed, which were controlled by faults. Based on satellite gravity and the digital elevation model （EGM2008）, by using the technology of wavelet multi-scale analysis and horizontal gradient modulus, we discuss the regional geological characteristics in the Guangxi area.
