Electrical conductivity during incipient melting in the oceanic low-velocity zone [PDF]

, 2014
International audienceThe low-viscosity layer in the upper mantle, the asthenosphere, is a requirement for plate tectonics1. The seismic low velocities and the high electrical conductivities of the asthenosphere are attributed either to subsolidus, water-

How Sediment Supply, Sea‐Level, and Glacial Isostatic Oscillations Drive Alluvial River Long‐Profile Evolution and Terrace Formation

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract For over a century, alluvial river terraces have been used as archives of tectonic deformation or changes in water discharge, sediment supply, and sea level. Despite this long history, such efforts remain challenging: using terraces as deformation markers requires knowledge of their initial geometry, and most attempts to attribute terrace ...

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.

Tectonic Inheritance During Plate Boundary Evolution in Southern California Constrained From Seismic Anisotropy

Geochemistry, Geophysics, Geosystems, 2021
The style of convective force transmission to plates and strain‐localization within and underneath plate boundaries remain debated. To address some of the related issues, we analyze a range of deformation indicators in southern California from the ...

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-

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Imaging Lithospheric Discontinuities Beneath the Northern East African Rift Using S‐to‐P Receiver Functions

Geochemistry, Geophysics, Geosystems, 2018
Imaging the lithosphere is key to understand mechanisms of extension as rifting progresses. Continental rifting results in a combination of mechanical stretching and thinning of the lithosphere, decompression upwelling, heating, sometimes partial melting

Subduction System Response to Ribbon Collision: Implications on the Intra‐Plate Force Balance and the Style of Slab Deformation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Ribbon collision is a process that can rapidly disturb the symmetry of subduction zones. Previous studies have demonstrated how ribbon collision causes rotation at the surface and contortion in the slab, but have only focused on the surface kinematics.

Seismic and isotopic evidence for depth-dependent mantle sources of intraplate basalts from Eastern China

Communications Earth & Environment
The origin of intraplate basalts remains controversial, despite numerous isotope and seismic studies. Here we employ thermodynamic modeling with MAGEMin to integrate the Sr-Nd-Hf isotopes of basaltic volcanics with the seismic velocities of their mantle ...
