Allowance for the Earth’s Surface Topography in Processing the Magnetic Field Measurements
Abstract
The questions concerning the allowance for the Earth’s surface topography in the measurements of the magnetic field in mountainous regions are considered. The new method is suggested for estimating the influence of the sharply contrasting relief composed of the strongly magnetized rocks on the results of the field observations. The method uses the decomposition of the magnetic field and elevation data in the empirical modes with subsequent application of the method of group allowance for arguments. The results of reducing the airborne magnetic survey carried out n the northwestern part of the Siberian platform above the copper-nickel ore deposit are presented.
