The geology and hydrogeology of the Liptovská Kotlina Depression were studied by means of new geophysical methods. Controlled source audio-frequency magnetotellurics enabled us to delineate the relief of the pre-Cainozoic basement in the western part of ...

A note on the topographic distortion of magnetotelluric impedance
Magnetotelluric surveys are prone to interpretation errors in the presence of rough topography, which may need to be compensated for. In the present work we assume that the surface of the Earth is simulated by a single-valued, twice differentiable ...

The Relationship Between Kimberlitic Magmatism and Electrical Conductivity Anomalies in the Mantle
Kimberlites are igneous rocks whose formation remains enigmatic due to their severely altered nature, highly variable compositions and rapid ascent through the lithosphere.

Detecting a salt dome overhang with magnetotellurics: 3D inversion methodology and synthetic model studies [PDF]
Detecting a salt dome overhang is known to be problematic by seismic methods alone. We used magnetotellurics (MT) as a complementary method to seismics to investigate the detectability of a salt dome overhang.

For electromagnetic (EM) modeling based on the electric-field formulation at low frequencies, the quasi-static approximation (i.e., only the conduction current is considered and the displacement current is ignored) is commonly applied, and a small ...

A new petrological and geophysical investigation of the present-day plumbing system of Mount Vesuvius [PDF]
Article in PressInternational audienceA model of the electrical resistivity of Mt. Vesuvius has been elaborated to investigate the present structure of the volcanic edifice. The model is based on electrical conductivity measurements in the laboratory, on
