Advances in aspects of the application of magnetotellurics for mineral exploration

Abstract:

The high-frequency magnetotelluric method, audio-MT dramatically both diurnally and seasonally, and with solar (AMT), is currently being widely used for mining exploration, activity. The ionospheric layers are formed of particles that especially in Canada. However, there are still some aspects are electrically charged and that attenuate EM waves. The regarding its implementation that need to be considered. diurnal variation in attenuation is due the lower conductivity These range from signal detection and processing to response of the atmosphere at night because of the smaller aerosol function analysis to appreciation of three-dimensional effects. content (no sun activity). This results in higher penetration of The main natural electromagnetic source at the range of Sudbury (northern Ontario) and in northern Germany, we frequencies covered by mining scale MT, audio-frequencies have studied this diurnal variation …
