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。本文根据最新卫星地磁场模型(NGDC-720),特别运用总磁场异常模量及小波多尺度分析等新技术,对广西地区区域地磁特征以及岩浆岩分布等进行了相关讨论。Guangxi that belongs to the southern Paleozoic Yangtze plate is located in continental margin belt of southeastern China,at the binding site of Huaxia plate and Indo-China plate.In history,with different periods of volcanic eruption and its intrusion,a variety of metal ores are formed and are obviously under the control of the fault structure.Based on the new satellite magnetism model（NGDC-720）,especially by using the technology of total magnetic anomaly modulus and wavelet multi-scale analysis,we discuss the geomagnetic characteristics and distribution of magmatic rocks in Guangxi area.
