Abstract: Abstract Broadband and long-period magnetotelluric (MT) data were used to obtain a continuous image of the lithospheric electrical conductivity structure across the southeastern Tibetan Plateau margin, where long-wavelength crustal thickening and surface uplift have been… read more here.

DOI: 10.1016/j.jappgeo.2019.103919
Abstract: Abstract De-noising the magnetotelluric (MT) data using the conventional time-series editing methods is at the risk of losing low-frequency signals, especially the signal below 1 Hz. To overcome this deficiency, we propose a combinatorial method based… read more here.

DOI: 10.1093/gji/ggac029
Abstract: SUMMARY The footprint of a mineral system is potentially detectable at a range of scales and lithospheric depths, reflecting the size and distribution of its components. Magnetotellurics is one of a few techniques that can… read more here.

DOI: 10.3103/s0145875219060139
Abstract: Two applications of 3D inversion of magnetotelluric data using the Lomonosov supercomputer are discussed. The effectiveness of the chosen inversion approach for several real geological objects is demonstrated. Each object belongs to a different class… read more here.
