Abstract
Summary
The problem of taking into account the influence of the relief of the earth’s surface when measuring the magnetic field over the plateaubasalts is considered. A new method is proposed for assessing the effect of sharply dissected relief composed of intensely magnetized rocks on the results of field observations. The decomposition of data on the magnetic field and altitude marks into empirical modes is used, and also the subsequent application to the received components the Group Method of Data Handling (GMDH). The results of reduction of the aeromagnetic survey performed in the northwest of the Siberian platform over the copper-nickel ore deposit are presented.
