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 ...

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 kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current
