Computing Effective Elastic Properties From Microtomographic Images: An Efficient 3D Digital Rock Workflow

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Digital rock physics (DRP), using high‐resolution 3D microtomographic rock images, is widely employed to predict elastic and transport properties of subsurface formations. Accurate microstructural characterization is often hindered by limited image resolution and overlapping grayscale values of minerals. Consequently, DRP simulations are often

Relative Source Time Functions, Spectral Ratios, and Near‐Source Spallation in the Source Physics Experiment Phase I Chemical Explosions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The Source Physics Experiment (SPE) Phase I was composed of six chemical explosions at the Nevada National Security Sites (NNSS) between 2011 and 2016. The experiment provided a robust set of dense, local to regional distance observations suitable for characterizing shallow chemical explosions located within the same borehole.

Two‐Layer Anisotropy Beneath Subduction Zones: Bayesian Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Shear‐wave splitting measurements have the potential to constrain multiple layers of anisotropy and thereby enhance depth resolution. Using the formulation of Silver and Savage (1994, https://doi.org/10.1111/j.1365‐246x.1994.tb04027.x), previous studies have employed deterministic grid‐search approaches to identify best‐fitting two‐layer ...

Grain‐Scale Heterogeneity in Fault Veins Influences Shear Rupture, Damage Distribution, and Microseismicity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Fault veins, mineral‐filled fractures within fault zones, exhibit substantial grain‐scale structural variation, yet, the mechanical consequences of this heterogeneity on fault deformation and seismicity remain poorly constrained. Here, we use the Discrete Element Method to investigate how grain‐scale heterogeneity in quartz veins, which are ...

D‐Rex++: A New Tool to Simulate Olivine's Crystallographic Preferred Orientation in the Upper Mantle With Grain Size‐Coupled Rheology

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Understanding the co‐evolution of olivine's crystallographic preferred orientation (CPO) and grain size is essential for capturing the dynamics of Earth's upper mantle. Existing CPO evolution models, such as D‐Rex, successfully predict CPO development but overpredict CPO strength and do not provide a physically meaningful grain size, limiting ...
