Abstract

Vertical magnetic measurements were carried out along three chosen profiles to have an insight and inference about the subsurface geology and structures of Schirmacher region of east Antarctica. The interpretation of magnetic profiles based on amplitude analysis using the Hilbert transform and traditional Fourier spectral analysis in frequency domain reveal certain structural features such as faults/ contacts at shallow depth. Depths from modeling of the magnetic anomalies agree well with the interpreted depths particularly in the case of profiles II and III. Measured densities and magnetic susceptibilities of the rock samples are found to be marginally high in some cases in comparison with those of the Indian Peninsula.
