High‐Resolution 3‐D Lithospheric Structure of the Subducting Carnegie Ridge and the Ecuadorian Margin Imaged From Teleseismic Receiver Functions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Ecuadorian margin is a forearc‐arc system shaped by oceanic terrane accretion and Carnegie Ridge subduction, yet the accretion mechanism and ridge subduction extent remain poorly constrained. Using teleseismic P‐wave receiver functions from dense seismic arrays, we image velocity discontinuities within the overriding plate and subducting ...

Light Element Exsolution in Fe‐Si‐C‐(H) System: A Mechanism for Powering Mercury's Early Core Dynamo

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mercury is one of the few terrestrial planets in the solar system with a magnetic field, yet the energy source to power its core dynamo remains unclear to date. Si, C, and possibly H are the top candidate light elements for its liquid core. Here, we showed experimentally that Si, C, and H in Fe‐Si‐C and Fe‐Si‐C‐H liquids share a simultaneous ...

Limits of Water Storage in Stishovite at Deep Mantle Conditions

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The deep Earth water cycle is a key process in Earth's evolution. Stishovite has been proposed as a major carrier of water from the surface into the lower mantle. However, its role remains unclear because its water solubility is controversial. We investigated the water solubility of Al‐free stishovite at pressures of 33–38 GPa and temperatures

High‐Resolution Tomography for the Upper‐Mantle Structure in North China by Full‐Waveform Inversion of Teleseismic P Wave and Its Codas

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We investigate the structure and tectonic environment in the crust and upper mantle beneath the North China Craton (NCC) by conducting a full‐waveform inversion of teleseismic P and its coda waves from densely distributed broadband seismic stations. A high‐resolution model involving P‐ and S‐wave velocities as well as density is constructed by

Alteration of a Mantle‐Derived Dunite Boulder in Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In 2023, the Mars 2020 Perseverance rover explored the youngest preserved deposits on the Western fan of Jezero crater, Mars: a field of meter‐scale boulders dispersed above the previously explored sandstone and siltstone units. Reflectance spectra of the boulders delineated two classes, one olivine‐bearing and one pyroxene‐bearing.
