WebJan 25, 2024 · Magnetotellurics ( MT) is an electrical geophysical technique that measures the resistivity of the subsurface. Although MT cannot provide the resolution of seismic surveys, it is less expensive and, more importantly, can be used in places where seismic data collection is impractical or gives poor results. This is the same physical parameter ... WebThis animation shows how Magnetotelluric (MT) Surveys Work. It is part of a series of Field Activity Technique Engagement Animations.

Magnetotellurics (MT) is an electromagnetic geophysical method for inferring the earth's subsurface electrical conductivity from measurements of natural geomagnetic and geoelectric field variation at the Earth's surface. Investigation depth ranges from 300 m below ground by recording higher … See more The magnetotelluric technique was introduced independently by Japanese scientists in 1948 (Hirayama, Rikitake), Russian geophysicist Andrey Nikolayevich Tikhonov in 1950 and the French geophysicist Louis … See more Hydrocarbon exploration For hydrocarbon exploration, MT is mainly used as a complement to the primary technique of reflection seismology exploration. While seismic imaging is able to image subsurface structure, it cannot detect the changes … See more Energy sources Solar energy and lightning cause natural variations in the earth's magnetic field, inducing electric currents (known as telluric currents) … See more MT exploration surveys are done to acquire resistivity data which can be interpreted to create a model of the subsurface. Data is acquired at each sounding location for a period of time (overnight soundings are common), with physical spacing … See more Crust and mantle Since the MT is highly sensitive to the composition and temperature of the Earth, it has been widely used to understand numerous geological phenomena in the Earth's mantle and crust.
