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 Zhuang Autonomous Region is located in the southeastern margin of China continental belt, belonging to the southern margin of the Paleozoic Yangtze Plate, east Huaxia plate, west of the Indo-China plate, in the three plate combination. Volatile volcanic history in history, with different periods of volcanic eruptions and intrusions, the formation of a variety of metal minerals, and obviously controlled by the fault structure. Based on the latest satellite geomagnetic field model (NGDC-720), especially using new techniques such as total magnetic field anomalous modulus and wavelet multiscale analysis, the paper discusses the regional geomagnetic characteristics and the distribution of magmatic rocks in Guangxi.
