Abstract: Abstract Cataclasis is a first-order mechanism shaping fault-rock development in the brittle crust. The most accepted model for cataclasis is “constrained comminution” which predicts a power-law distribution of particle size described by the fractal dimension,… read more here.

DOI: 10.1016/j.jseaes.2018.03.004
Abstract: Abstract As faults can be barriers to or conduits for fluid flow, it is critical to understand fault seal processes and their effects on the sealing capacity of a fault zone. Apart from the stratigraphic… read more here.

Abstract: As iron‐bearing minerals—ferrimagnetic minerals in particular—are sensitive to stress, temperature, and presence of fluids in fault zones, their magnetic properties provide valuable insights into physical and chemical processes affecting fault rocks. Here, we review the… read more here.

Abstract: Fault zones accommodate relative motion between tectonic blocks and control earthquake nucleation. Nanocrystalline fault rocks are ubiquitous in "principal slip zones" indicating that these materials are determining fault stability. However, the rheology of nanocrystalline fault… read more here.

DOI: 10.1038/s41598-022-05379-5
Abstract: Whether seismic rupture propagates over large distances to generate mega-earthquakes or is rapidly aborted mainly depends on the slip processes within the fault core, including particularly frictional melting or intense grain-size reduction and amorphization. The… read more here.
