Reaction‐Driven Crack Propagation Controlled by Vein Extension in a Dilute Fracture System

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Permanent mineral trapping of CO2 ${\text{CO}}_{2}$ in ultramafic rocks can be accelerated if carbonate precipitation wedges open microcracks and sustains crack growth, thereby increasing permeability and reactive surface area. We develop a vein‐extension controlled model for carbonation reaction‐driven cracking in a dilute fracture system ...

Active Normal Fault Segmentation and Linkage in the Umbria‐Marche Apennines (Italy): Insights From 3D Structural Modeling

open access: yesTectonics, Volume 45, Issue 10, October 2026.
Abstract Normal‐fault growth, segmentation, and their relationships with crustal inheritance and rheological layering are investigated in a post‐thrusting setting of the southern sector of the Northern Apennines. We integrate 3D modeling with gravity, thermal, and seismological constraints to reconstruct the geometry and evolution of the main normal ...

A New Experimental Design to Measure Second‐ and Third‐Order Anisotropic Rock‐Stiffness Coefficients Using a Single‐Rock Sample

open access: yesGeophysical Prospecting, Volume 74, Issue 8, October 2026.
ABSTRACT We developed a new experimental setup for measuring and modelling stress‐induced anisotropy and nonlinearity in cylindrical rock samples. Multidirectional ultrasonic velocity measurements were conducted under laboratory conditions and during triaxial‐stress testing to capture dynamic rock properties. This is done by placing endcap transducers (
