Geotribology-Friction, wear, and lubrication of faults

Y Boneh, Z Reches - Tectonophysics, 2018 - Elsevier
We introduce here the concept of Geotribology as an approach to study friction, wear, and
lubrication of geological systems. Methods of geotribology are applied here to characterize …

Rapid sliding and friction degradation: lessons from the catastrophic Vajont landslide

JP Ibañez, YH Hatzor - Engineering Geology, 2018 - Elsevier
We use the numerical, discrete element, Discontinuous Deformation Analysis (DDA) method
to study velocity-distance evolution of the catastrophic Vajont landslide using a newly …

Preferential formation of chlorite over talc during Si‐metasomatism of ultramafic rocks in subduction zones

EA Codillo, F Klein, HR Marschall - Geophysical Research …, 2022 - Wiley Online Library
Talc formation via silica‐metasomatism of ultramafic rocks is believed to play key roles in
subduction zone processes. Yet, the conditions of talc formation remain poorly constrained …

Weak phases production and heat generation control fault friction during seismic slip

H Rattez, M Veveakis - Nature Communications, 2020 - nature.com
The triggering and magnitude of earthquakes is determined by the friction evolution along
faults. Experimental results have revealed a drastic decrease of the friction coefficient for …

Episodic slow slip hosted by talc‐bearing metasomatic rocks: High strain rates and stress amplification in a chemically reacting shear zone

WF Hoover, CB Condit, PC Lindquist… - Geophysical …, 2022 - Wiley Online Library
Episodic tremor and slow slip (ETS) downdip of the subduction seismogenic zone are poorly
understood slip behaviors of the seismic cycle. Talc, a common metasomatic mineral at the …

Mantle exhumation at magma-poor rifted margins controlled by frictional shear zones

T Theunissen, RS Huismans - Nature communications, 2022 - nature.com
The transition zone from continental crust to the mature mid-ocean ridge spreading center of
the Iberia-Newfoundland magma-poor rifted margins is mostly composed of exhumed …

High‐Pressure Mechanical Properties of Talc: Implications for Fault Strength and Slip Processes

Y Boneh, M Pec, G Hirth - Journal of Geophysical Research …, 2023 - Wiley Online Library
The hydrous mineral talc is stable over a relatively large P‐T field and can form due to fluid
migration and metamorphic reactions in mafic and ultramafic rocks and in faults along plate …

Frictional behavior and micro-damage characteristics of rough granite fractures

F Meng, LNY Wong, T Guo - Tectonophysics, 2022 - Elsevier
Natural faults or discontinuities in general are usually rough at different scales, and the
roughness of fault surfaces plays a dominant role in determining the mode of sliding (stable …

Earthquakes as dynamic fracture phenomena

Z Reches, J Fineberg - Journal of Geophysical Research: Solid …, 2023 - Wiley Online Library
A large earthquake unlocks a fault‐zone via dynamic rupture while releasing part of the
elastic energy stored during the interseismic stage. As earthquakes occur at depth, the …

Two-dimensional talc as a van der Waals material for solid lubrication at the nanoscale
