Numerical models of fluid-filled fault zones: the effect of fluid flow on shear localization Academic Article uri icon

abstract

  • Abstract Slip on fault zones occurs within a gouge layer, which consists of a granular material of finely-ground rock that has worn off of the sliding surfaces. Within the gouge layer, the majority of shear is often further localized within narrow bands of grains. The development of this gouge layer and the forces that generate the deformation of the granular medium under constant shear has been extensively studied through both field studies and numerical models. However, there is still no comprehensive set of continuum governing …
