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 ...

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...

Seafloor Displacements Across the Mid‐Ocean Ridge Eruption Cycle Modulated by Mush Zone Viscosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Mid‐ocean ridges (MORs) are active volcanic systems where axial magma lenses (AMLs) are replenished on decadal time scales, enabling frequent dike intrusions. The associated seafloor deformation, however, remains scarcely understood. Here we assess this deformation by simulating cycles of steady AML inflation followed by instantaneous dike ...

Plate Divergence at the Krafla Volcanic System, Iceland: Insight From GNSS Geodesy and Sentinel‐1 Satellite Radar Interferometry in 2002–2024

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The Krafla volcanic system in Iceland, a subaerial segment of the divergent boundary between the North American and Eurasian plates, offers a unique opportunity to investigate volcano‐tectonic processes. We present a six‐segment kinematic back slip plate boundary model constrained jointly by long‐term deformation velocity fields from Global ...

Seismic Constraints on Igneous Intrusions and Fluid/Gas Distribution in a Continental Back‐Arc System: Evidence From the Yaeyama Rift in the Southern Okinawa Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The geometry and distribution of igneous intrusions, which define melt source locations and record syn‐emplacement stress conditions, are essential for understanding tectonic and magmatic processes associated with crustal extension. However, in back‐arc settings along continental margins, structural constraints on these features remain poorly ...
