Exhumed fault zones offer insights into deformation processes associated with earthquakes
in unparalleled spatial resolution; however it can be difficult to differentiate seismic slip from …

The structure, frictional properties and permeability of faults within carbonate rocks exhibit a
dynamic interplay that controls both seismicity and the exchange of fluid between different …

Classical rate‐and‐state friction (RSF) laws are widely applied in modeling earthquake
dynamics but generally using empirically determined parameters with little or no knowledge …

Recent friction experiments carried out under upper crustal P–T conditions have shown that
microstructures typical of high temperature creep develop in the slip zone of experimental …

We report an experimental and microstructural study of the frictional properties of simulated
fault gouges prepared from natural limestone (96% CaCO 3) and pure calcite. Our …

The constitutive behavior of faults is central to many interconnected aspects of earthquake
science, from fault dynamics to induced seismicity, to seismic hazards characterization. Yet …

The understanding of fault-slip behaviour in carbonates has an important societal impact
due to the widespread occurrence and propagation of earthquakes in these rocks. Fault rock …

We report ring shear experiments on simulated calcite fault gouges performed at fixed
temperatures (T) within the range from 20° C to 600° C. The experiments were performed …

Understanding the internal mechanisms controlling fault friction is crucial for understanding
seismogenic slip on active faults. Displacement in such fault zones is frequently localized on …

To determine the role of strain localization during dynamic weakening of calcite gouge at
seismic slip rates, single-slide and slide–hold–slide experiments were conducted on 2–3 …
