Magnetic Scanning of the Earth's Crust in Siberia from a stratospheric Aerostat

Abstract

Data from surface, aerostat (balloon), and satellite surveys were used in constructing profiles of the anomalous magnetic field of Siberia. Wavelet analysis of the profiles revealed a number of longitude inhomogeneities in the structure of anomalous magnetic fields. It is shown that the dynamics of anomalous fields is concentrated for the most part in the range of low values of the wavelet transformation scale factors. Good agreement between the estimates of depths to the sources on the basis of magnetic data and information on heat-flow distribution facilitates an understanding of the tectonic structure of this region.
