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 ...

Distinct Transcrustal Evolutions of Komatiitic Primitive Magma: Implications for the Compositional Dichotomy of Continental Flood Basalts

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The origin of the compositional dichotomy between high‐Ti and low‐Ti basalts in continental flood basalt provinces remains debated. Most existing studies attribute this dichotomy directly to variations in primitive magma composition to circumvent the complexities of significant evolutionary processes, such as multiphase fractional ...

Tertiary‐Ozone‐Maximum‐Like Mesospheric Ozone Increases Driven by Solar Eclipses: Sensitivity Experiments on WACCM‐X

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar eclipses offer natural experiments to isolate the photochemical response of mesospheric ozone to solar radiation. Using the WACCM‐X model, we performed mechanism‐oriented sensitivity experiments for the 14 December 2020 eclipse to quantify the tertiary‐ozone‐maximum‐like (TOM‐like) response.

A Contrasting TEC Behavior Over the Low‐Latitude Post‐Midnight Sector During Recovery Phases of May and October 2024 Storms: Possible Role of PPEF, DDEF, and O/N2

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The present study reports on the variability of the post‐midnight ionosphere over the low‐latitude sector during the recovery phases of the May and October 2024 storms. Multi‐instrument observations, comprising global navigation satellite system total electron content (TEC), F‐layer peak height, electron density profiles, and column O/N2 ...

Coincident ENA and Narrowband Radio Emissions as Diagnostics of Inward Plasma Transport at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Saturn's kilometric radiation (SKR) and Energetic Neutral Atom (ENA) emissions are important diagnostics of the planet's magnetospheric dynamics, intensifying during global plasma injections and displaying characteristic planetary periodicity. Related to the SKR emissions are myriametric narrowband radio emissions that typically appear in the ...
