| 摘 要： | 本文概括地叙述了匹配滤波提取区域磁场的原理、方法,并将东北地区的匹配滤波结果与向上延拓结果作了比较,说明了两个结果的异同点。着重分析了匹配滤波所得的东北地区区域磁场特征及它所反映的区域地质构造,指出华北地台北缘隆起带东延、华北地台北部存在西拉木伦褶皱系、松辽盆地内部的构造分区和东北东西向断裂的等间距性等。

| Abstract: | The principle and method of match filtering used for separating regional magnetic field out from total aeromagaetic field are described briefly.A comparison regarding the similarities and differences between the results obtained from match filtering and up continuation is made for northeast china.It is noted that the features of the regional magnetic field obtained through match fieltering method fit the regional geological structures well, and furthermore, dioclose the eastward extension of the uplifting zone on the northern margin of the North China platform, the existence of Xilamulun fold system in the northern part of the North China platform, the structural framework of the Songliao Basin, and the equalspaced east-west striking faults in that basin, and so on. |
