Magnetotelluric Systems at PASSCAL

Magnetotelluric (MT) methods are used to produce conductivity models of the crust and upper mantle through the recording of geoelectric and geomagnetic field variations at the Earth's surface. Depending on the period of the recordings, these methods can provide results from a few hundred meters depth (short period) to 30 km or deeper (long period). Conductivity is a physical property, which is complementary to seismic velocity, and which is very sensitive to the presence of fluids. When seismic and MT data sets are measured together, the additional data can dramatically improve determinations of the structure of the crust and mantle.

 

 

Since 2019, the EPIC (formerly known as PASSCAL) has been developing MT resources to meet PIs needs. We currently have a wide pool of MT equipment including both long-period (LEMI) and wideband (Phoenix) systems.
