Long‐Term Deformation in the Alpine‐Provence Foreland Constrained by In Situ Calcite U‐Pb Dating

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract The evolution of the Alpine‐Provence foreland is characterized by multiple deformation phases since the Mesozoic, representing successive compressional and extensional episodes. The precise timing and spatial evolution of these deformation phases remain poorly constrained due to the lack of absolute geochronological data. Here, we present U–Pb

Subducting Slab Thermo‐Petrologic Structure and Intermediate‐Depth Supra‐Slab Earthquakes Beneath Southern Colombia

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We develop 2‐D thermo‐petrologic models for two transects through southern Colombia and compare the model‐predicted temperature distributions and depths of slab dehydration with seismological observations. Along the northern transect, earthquakes occur above the relatively young subducting Nazca slab at 80–160‐km depths.

The Fate of Iron Formations in the Deep Mantle: Constraints From Iron Oxide Reduction Kinetics Experiments

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dense sedimentary iron formations (IFs) subducted into the mantle during Earth's early history, may have descended to the core‐mantle boundary where they could exert strong control on its thermal and seismological properties. A key unanswered question is the extent to which IFs retain their oxidized character in the much more reducing mantle ...

Reply to comments by H. Mashima on 'Evolution of the eastern margin of Korea: constraints on the opening of the East Sea (Japan Sea)' by Kim et al. [Tectonophysics 436 (2007) 37-55]

open access: yes, 2008
We thank H. Mashima for his interest in our recent article in Tectonophysics [Kim, H.J., Lee, G.H., Jon, H.T., Cho, H.M., Yoo, H.S., Park, G.T., Kim, J.S., 2007, Evolution of the eastern margin of Korea: Constraints on the opening of the East Sea (Japan ...

Poromechanical and Crack Evolution of Olivine‐Rich Rock During Serpentinization

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Serpentinization alters the strength, fracture behavior, and rheology of ultramafic rocks, yet the coupled evolution of mineral reactions, cracking, and mechanical softening remains poorly constrained. We experimentally simulated serpentinization in dunite at 220°C and 15 MPa for 14 and 30 days and compared the reacted specimens with dry heat ...

High‐Pressure Elasticity of CAS Phase and Its Implications for the Fate of Subducted Anorthosite Crust

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The CAS phase (CaAl4Si2O11) is a key phase formed in subducted silica‐alumina rich crustal and sedimentary materials under the mantle transition zone conditions. In this study, its elastic properties were investigated using first‐principles calculations up to 30 GPa.
