Weakening Processes in Carbonate‐Hosted Faults: Phyllosilicate Microlayers and Injections Along the Mattinata Fault (Southern Italy)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Micrometric phyllosilicate films along fault slip surfaces (SSs) can drastically reduce friction, yet they are unexpected in clay‐poor carbonate platforms. We inquire how a major carbonate‐hosted, seismogenic strike‐slip fault can develop weak slip interfaces and undergo dynamic weakening despite an intrinsically strong host rock.

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

open access: yesTectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

Prediction of Fault and Fracture Density From Seismic Attributes and Machine Learning Models Calibrated With Borehole Image Logs

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.
