Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Intraplate volcanism in Northeast Asia, located in a distant back‐arc setting, challenges conventional models of mantle convection and volatile cycling. Using receiver function data from over 300 broadband stations, we image the mantle transition zone (MTZ) beneath the Changbaishan/Paektu volcano.

Geophysical Research LettersThe Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and

Geodynamic Significance of Intraplate Basaltic Magmatism From the Western Mediterranean Region
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Dynamic topography changes as mantle convection evolves, making its past surface expression difficult to reconstruct. Widespread Neogene‐Quaternary intraplate basaltic magmatism across the Western Mediterranean Region allows us to test whether dated basalts preserve the mantle thermal structure responsible for regional dynamic support.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

Flip‐Flop Detachments Require Moderate Strength Contrasts Between Fault Zone and Fault Blocks
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Large‐offset detachment faults frequently occur at slow‐ and ultraslow‐spreading mid‐ocean ridges, especially where magma supply is limited. Observations show that detachments at ultraslow ridges often alternate in polarity (“flip‐flop” regime), but the mechanical controls governing their formation remain poorly understood.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...
