Multi‐Scale Electrical Conductivity Model of the Contiguous United States
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The completion of the Magnetotelluric (MT) USArray across the contiguous US enables continental‐scale 3‐D imaging of the asthenosphere‐lithosphere electrical structure. We present a novel 3‐D model of the contiguous United States (MECMUS), derived from a single inversion of the now‐completed USMTArray data set.

The electrical structure of the central Pacific upper mantle constrained by the NoMelt experiment
Geochemistry, Geophysics, Geosystems, 2015 The NoMelt experiment imaged the mantle beneath 70 Ma Pacific seafloor with the aim of understanding the transition from the lithosphere to the underlying convecting asthenosphere.

Investigating the Antarctic Lithosphere Through Sp Receiver Function Analysis
Geochemistry, Geophysics, GeosystemsTo better understand the lithosphere of Antarctica, we imaged its lithosphere‐asthenosphere boundary (LAB) and crust‐mantle transition using Sp receiver functions from teleseismic events analyzed at individual stations and with common conversion point ...

Lithosphere-asthenosphere system in shield areas of North America and Europe
Annals of Geophysics, 1997 In previous papers surface dispersion data have been combined with the results of deep seismic refraction data to derive a regionalization of the lithosphere-asthenosphere system and to investigate the presence of significant heterogeneity down to depths

Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]
, 2006 Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

Satellite tidal magnetic signals constrain oceanic lithosphere-asthenosphere boundary
Science Advances, 2016 Researchers present results on the oceanic upper mantle electrical structure revealed by satellite-detected tidal magnetic signals. The tidal flow of electrically conductive oceans through the geomagnetic field results in the generation of secondary ...

Antarctic Record, 1998 Linear deformation laws have been applied to post glacial rebound, while many speculations based on real rock samples support non-linear rheology in the upper mantle. Essential information is required to support the assumed constitutive relation.
