Mathematical provision for interpretation of field of regional magnetic anomalies

© Kovalenko-Zavoyskiy V.M., Ivashchenko I.M.

Algorythms for interpretation of Δ field of regional magnetic anomalies (RMA) are proposed, which include interpolation of normal geomagnetic field on spherical surface, solution of direct problem of magnetometry in spherical coordinates, linearization of Δ function in relation to components of the vector of anomalous magnetic field. It has been shown that linearization allows to give interpretation of Δ in linear setting of inverse problem as to magnetization of RMA sources with sufficient accuracy.
