Geotribology-Friction, wear, and lubrication of faults
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 …

Dynamic weakening by nanoscale smoothing during high-velocity fault slip
Slip during large earthquakes occurs along faults that are hundreds of kilometers long, yet
the dynamic weakening that drives these earthquakes is controlled by nano-to micro-scale …

Fault wear by damage evolution during steady-state slip
Slip along faults generates wear products such as gouge layers and cataclasite zones that
range in thickness from sub-millimeter to tens of meters. The properties of these zones …

Modeling dynamic-weakening and dynamic-strengthening of granite in high-velocity slip experiments
Earthquakes are associated with slip along fault-zones in the crust, and the intensity of
dynamic-weakening is one of the central questions of earthquake physics (Dieterich, 1979; …

Wear of geo-materials by mechanical impulse
Shear along rock faults is always associated with wear of the sliding blocks that commonly
results in the production of fine powder called gouge. We experimentally analyzed intensity …
