摘要：
Magnetotelluric sounding (MTs, including audio-magnetotelluric, broadband-magnetotelluric and long-period-magnetotelluric) is a geophysical method to probe the near-surface to the upper mantle. Due to its sensitivity to low resistivity bodies, magnetotelluric plays an important role in deep structure, seismogenic environment, geothermal and resource exploration and geodynamics. The Sichuan-Yunnan region, located in the eastern section of the Tethys tectonic domain where many (micro) plates collide and merge, serves as an important channel for the eastward flow of materials and lateral extrusion of blocks within the Tibetan Plateau. The region is an important window to study the regional tectonic deformation, seismogenic environment and material migration due to the mutual cutting and influence of fault zones or suture zones of the plate boundary. This review first gives a brief introduction to the theory of magnetotelluric, then focuses on its application in the Sichuan-Yunnan region as well as the emerging CSELF (control source extremely low frequency) electromagnetic technique in recent years, and finally discusses the application of magnetotelluric in seismogenic environment, volcanic and geothermal activities, metallogenic activities, tectonic and dynamics, and electromagnetic coseismic effects. This review offers a comprehensive perspective on the application of magnetotelluric in the Sichuan-Yunnan region. © 2024 Science Frontiers editorial department. All rights reserved.
