- Abstract:
-
Based on the observation data of the 4 periods of total intensity of geomagnetism during 2015 and 2016 obtained from the Xiaojiang fault and its surrounding regions,the distribution of the variation of curiosive and the lithosphere magnetic field anomalies in the deep and shallow areas.Then the characteristics of the magnetic field of the Xiaojiang fault are analyzed.The results show that:(1)The lithosphere magnetic field anomalies of Xiaojiang fault are generally enhanced from south,middle to north;(2)In the vicinity of Gejiu and Ludian,the characteristics of the magnetic field of lithosphere anomalies are obvious.In the temporal domain,the energy of the magnetic field near Gejiu shows the characteristics of enhancement,attenuation and then enhancement.(3)From August,2015 to March,2016,the obvious boundary of the magnetic field energy enhancement and weakening appeared in the distribution of the lithosphere magnetic field anomalies in the deep and shallow areas.
