Growth and Chemical Evolution of the Kohistan Arc Crust, Northern Pakistan, Western Himalayas

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil arcs which expose the middle‐lower crust have the potential to shed light on active arc processes because magmatic rocks from the entire history of the arc can be examined. We present new geochemical data from the middle crust of the Kohistan Arc and use existing geochemical and geochronological literature data from this arc to ...

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part II Applications

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Compaction bands, desiccation cracks, and melt segregation structures are geological patterns relying on the same fundamental manifestations of a universal Turing‐type instability mechanism, as predicted by the thermodynamically consistent reaction–cross‐diffusion framework developed in Part I (Regenauer‐Lieb et al., 2025, https://doi.org/10 ...

Cenozoic Subduction Polarity Reversal Within the Celebes Sea Inferred From Teleseismic Tomography

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Sulawesi and Borneo are tectonically complex islands with multistage subduction histories stretching back through the Cenozoic. Seismic studies have played an important role in helping to unravel this history, with spatial distributions of earthquakes tracking actively subducting slabs. In contrast, old or relict aseismic slabs are illuminated

Comparing Slab Viscous Dissipation Under Slab Distributed Weakening and Slab Segmentation Scenarios

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction of cold, dense oceanic lithosphere is a key driver of plate tectonics and mantle convection. However, how much gravitational potential energy is internally dissipated by slab deformation during subduction remains debated and largely depends on the mechanisms of slab weakening.

Effect of Dislocations on Polycrystal Anelasticity Inferred From In Situ Forced Oscillation Test

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract To understand the effect of dislocations on the velocity and attenuation of seismic waves, the anelasticity of polycrystalline samples was measured in situ during dislocation creep. We used polycrystalline borneol as a rock analog. Because the effects of grain boundary mechanism on the anelastic properties of this material are well known ...
