Magnetotelluric sampling theorem

Earth, Planets and Space, 2023
Abstract We consider a general case of a magnetotelluric (MT) study to reveal three-dimensional (3D) distribution of the electrical conductivity within the Earth based on measurements of electromagnetic (EM) fields by a two-dimensional (2D) array.

Practical Magnetotellurics [PDF]

Eos, Transactions American Geophysical Union, 2006
Practical Magnetotellurics lives up to its title and nicely fills a big hole in the literature on the subject of the magnetotelluric (MT) method, a means by which the geological and physical properties of the crust and mantle may be studied using electrical conductivity images.In an MT sounding passive time series, measurements of the Earth's naturally

ECloud - Magnetotelluric Webapp [PDF]

ASEG Extended Abstracts, 2018
Geophysical web applications are highly underrated. There are many potential benefits for transitioning to a cloud based web applications including compatibility improvement, low on-going operating costs and better access to existing third-party code and tools for facilitating rapid development.

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Magma and Volatile Pathways Beneath Sakurajima Volcano From Self‐Potential, Helium Isotopes, and Broadband Magnetotellurics

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

Seismic Attenuation Reveals Fault and Forearc Structure Across the Subduction‐Collision Transition in Southern Taiwan

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) provides a new window into the subduction‐collision transition zone in southern Taiwan, where the Eurasian Plate‐Luzon Arc convergence drives intense orogeny and crustal deformation. Using dense P‐ and S‐wave spectral amplitude data recorded by SALUTE and a quality
