It is increasingly apparent that faults are typically not discrete planes but zones of deformed
rock with a complex internal structure and three-dimensional geometry. In the last decade …

Crustal deformation is inherently complex because the crust is inhomogeneous and
anisotropic on a wide variety of scales. Advances in our understanding have come from a …

Sliding on faults in much of the continental crust likely occurs at hydrothermal conditions, ie,
at elevated temperature and elevated pressure of aqueous pore fluids, yet there have been …

The presence of weak phyllosilicates may explain the low shear strengths of fault zones if
they define well‐developed fabrics. The growth of phyllosilicates is favored in meteoric water …

Some faults are considered strong because their strength is consistent with the Coulomb
criterion under Byerlee's friction, 0.6< μ< 0.85. In marked contrast, numerous studies have …

A growing body of evidence suggests that fluids are intimately linked to a variety of faulting
processes. These include the long term structural and compositional evolution of fault zones; …

Field and laboratory observations suggest that the porosity within fault zones varies over
earthquake cycles so that fluid pressure is in long-term equilibrium with hydrostatic fluid …

Deformation and chemical reaction in granitoids at greenschist faciès conditions were
investigated in samples from three shear zones: two from the Alps (Corvatsch Granodiorite …

We have shortened 15 schists and gneisses with varying compositions (15–75% mica by
volume) at angles (β) of 45° and 90° to foliation (S) to investigate the influence of micas on …

The basal slip systems of biotite and their mechanical expressions have been investigated
by shortening single crystals oriented to maximize and minimize shear stresses on (001) …
