Permeability Evolution and Gouge Formation During Fracture Shearing

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Hydro‐mechanical processes are crucial in shear‐controlled geoscientific applications such as enhanced geothermal systems and often result in stress‐dependent permeability changes. The present study aims to investigate shear‐induced permeability evolution of a natural sandstone fracture using a novel modeling approach.

Identifying Framboidal Pyrrhotite: A Proxy for Hydrothermal Alteration of Organic‐Rich Sediments

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Framboidal pyrrhotite, in sharp contrast to framboidal pyrite, has been rarely reported, and its formation remains poorly understood. Here we report its clear identification in a shale‐gas well core and explore its potential as a proxy for diagenesis or low‐grade metamorphism of organic‐rich sediments.
