Journal of Geophysical Research: Solid Earth, 1987
The study of the electrical conductivity structure of the lower crust and the upper mantle and midmantle promises to place important constraints on the thermobaric and compositional state of the earth's interior. Such work, particularly for depths above approximately 400 km, is best attempted by magnetotelluric sounding, an effort frustrated by the ...

Magnetotellurics (MT) is an electromagnetic, passive geophysical method that permits to explore the electrical resistivity distribution inside the Earth. It takes advantage of the naturally variable geomagnetic field at Earth's surface that induces secondary electromagnetic field in the diffusive limit.

The distortion of the magnetotelluric impedance tensor by complex “near‐surface” structure leads to leakage between the elements of the tensor. The magnetotelluric impedance tensor for our principal model, which has both a local and a regional strike, can be written in the long‐period limit as a sum of the regional, undistorted impedance and a ...

The magnetotelluric method is a technique for imaging the electrical conductivity and structure of the Earth, from the near surface down to the 410 km transition zone and beyond. This book forms the first comprehensive overview of magnetotellurics from the salient physics and its mathematical representation, to practical implementation in the field ...

Directional noise cancelling in magnetotellurics
55th EAEG Meeting, 1993In Magnetotelluric (MT) data processing, poor signal-to-noire ratio usually biaces the impedance tensor Z elements estimates. Strong electromagnetic (EM) noise may thus render the MT method impracticable in industrial areas. Noise due to periodic sources (i.e. power line harmonies) is easily removed by analog filtering in the field; but non-periodic EM

Magnetotelluric and Radio-Magnetotelluric Investigation, an Example from Midsommar Island, Sweden
GEO 2010, 2010Electromagnetic methods are powerful and widespread geophysical methods that can be employed to delineate the electrical resistivity/conductivity of Earth materials. Magnetotelluric data and Radio-magnetotelluric data were collected in year 2000 at one site located on the Midsommar Island, west of Stockholm.
