THE RESULT OF MATCH FILTERING ON THE AEROMAGNETIC MAP(1:1000000)OF NORTHEAST CHINA AND ITS GEOLOGICAL INTERPRETATION

Dong Huancheng  
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.
