Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Quantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite. However, constraining the amount and composition of common Pb, as well as the timing of its entrapment, remains a persistent challenge.

The Influence of Elevated Temperature on Time‐Dependent Compaction Creep in Bleursville Sandstone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The inelastic compaction of sandstone in the upper crust typically occurs at depths where temperatures range from approximately 50°C $50{}^{\circ}\mathrm{C}$ to 150°C $150{}^{\circ}\mathrm{C}$. Previous experimental studies have shown that even this modest temperature increase can reduce the yield stress required to initiate inelastic ...

Fracture‐Assisted Pressure Solution Creep of Granite: An Example From the Mont Blanc Massif, Western Alps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...

Chemical‐Thermomechanical Modeling of Open‐System Mass Transfer: Application to the Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract One of the main limitations in simulating subsolidus metasomatism is the decoupling between thermomechanical models and chemical/thermodynamic modeling. This decoupling amplifies the uncertainty associated with mass transport. Here, we introduce a fluid‐rock chemical‐thermomechanical interaction scheme, which integrates thermodynamic modeling (
