Tectonic Evolution and Crustal Growth of the East Kunlun Orogen, NW China: Insights From the Late Permian–Triassic Granitoids

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The East Kunlun Orogen (EKO) on the northern margin of the Tibetan Plateau experienced complex Late Paleozoic–Early Mesozoic tectono‐magmatic activities associated with the subduction and closure of the Paleo‐Tethys Ocean. Controversies remain regarding the timing and processes of the transition from subduction to collision and post‐collision,

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 ...

A Graphical User Interface Application to Model Open‐System Melting in the Upper Mantle

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The mantle partial melting process is crucial for the physicochemical evolution of the Earth's upper mantle and the generation of mafic crust. The open‐system melting model incorporates continuous melt segregation, interaction with melts or fluids, and crystallization of trapped melt and therefore provides a comprehensive model for simulating ...

Evolution in Fluid Composition During Subduction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Fluid‐rock reactions play important roles in seismicity, arc‐magma chemistries, and volatile cycling at convergent plate boundaries. In subduction environments, metamorphic reactions involving hydrous fluids facilitate metasomatic alteration and mass transport.

Carbonate Clumped Isotopes (Δ47) in Cenozoic “Island Dolostones”: Dolomitization Driven by Modified Seawater at Earth‐Surface Conditions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Dolomite [CaMg(CO3)2] is abundant throughout the geological record and constitutes a major component of many ancient carbonate platforms, yet the mechanisms responsible for its formation under Earth‐surface conditions are equivocal. Given that modern examples of low‐temperature dolomitization are rare, Cenozoic “island dolostones” provide ...
