Quantifying the role of hydrothermal alteration in creating geothermal and epithermal mineral resources: The Ohakuri ignimbrite (Taupō Volcanic Zone, New Zealand)
Hydrothermal fluids can alter the chemical and physical properties of the materials through
which they pass and can therefore modify the efficiency of fluid circulation. The role of …

The role of grain size and effective normal stress on localization and the frictional stability of simulated quartz gouge
For earthquakes to occur on tectonic faults deformation localizes onto discrete slip surfaces
within the gouge material of the fault core. Here, we investigate how localization is promoted …
