Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract Oceanic lithosphere formed at the global mid‐ocean ridge system makes up >60% of Earth's solid surface. Its uppermost ∼6 km are accreted either magmatically, where mafic melt is available, or tectonically, where this melt is absent. The magmatically accreted lithosphere is known to evolve with age, as demonstrated by its velocity increase ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract The Cenozoic topographic growth of the Iranian Plateau, situated at the Arabia‐Eurasia collision front, provides insights into continental collision dynamics. However, the relative contributions of tectonic shortening versus deep mantle processes to crustal thickening remain debated because systematic quantitative constraints on paleo‐crustal ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract Despite its importance in modeling the interior dynamics of a planet, our understanding of interior rheology remains incomplete because of several reasons, including insufficient experimental data and inadequate analysis of the available data.

Highly Enriched and Heterogeneous Mantle Signals Recorded in Mantle Pyroxenite Veins
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract The Earth's mantle is inherently heterogeneous, reflecting ongoing mantle depletion and crustal recycling driven by plate tectonics. Radiogenic isotopes in oceanic basalts are commonly used to characterize mantle reservoirs, but the full chemical diversity of mantle‐derived melts may be obscured by magma mixing during melt transport and ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract The diverse volcanic activity in the Alaska Peninsula section of the Alaska‐Aleutian subduction zone is presumably caused by substantial variations in mantle wedge melting or trans‐crustal processes beneath the arc. In this study, we investigate sub‐arc melting beneath the Alaska Peninsula by measuring P‐wave attenuation, as attenuation is ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Accurate interpretation of time‐variable gravity from GRACE (‐FO) requires correction for glacial isostatic adjustment (GIA), which has a gravitational signal similar in magnitude to that of contemporary hydrological and cryospheric mass change.

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...
