Full‐Waveform Seismic Tomography of the Upper Mantle Beneath the Arabia‐Eurasia Collision Zone

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Despite being one of the most recent major orogenic events, the timing of the Arabia‐Eurasia collision is still debated. Much of the discrepancy arises due to uncertainties over the amount of continental subduction of the Arabian passive margin and the timing of a hard collision of cratonic Arabian lithosphere with Eurasia.

OIB‐Type Garnet Amphibolites From the Xuerongzangbu Area, Central Lhasa Terrane, Tibet: Implications for Songduo Paleo‐Tethys Ocean Evolution and Permian Mantle Activity Along North Gondwana

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Whether the Songduo metamorphic belt represents an in situ Paleo‐Tethyan suture within the Lhasa Terrane or far‐traveled allochthonous high‐pressure slices, and how Permian mantle activity along the North Gondwana margin relates to subsequent Tethyan evolution, remain central questions in Tibetan tectonics.

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

Multiple Subduction–Exhumation Cycles and Episodic Hydration–Metasomatism of an Oceanic Eclogite Block: Implications for Thermal Structure Evolution and Mass Transfer at the Subduction Interface

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The rarity of natural rocks that specifically record the physicochemical conditions of the subduction interface strongly hampers pertinent studies on metamorphic trajectories of high‐pressure (HP) rocks and related fluid–rock interactions. This study examines an oceanic eclogite block from the Huwan shear zone in the Hong'an orogen.

Unraveling the Evolution of Silicic Volcanism in a Distributed Volcanic Field: Insights From Harrat Khaybar, Western Saudi Arabia

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.
