Fault rocks and fault mechanisms
  • R. Sibson
  • Geology
  • Journal of the Geological Society
  • 1 March 1977
Physical factors likely to affect the genesis of the various fault rocks—frictional properties, temperature, effective stress normal to the fault and differential stress—are examined in relation toExpand

Generation of Pseudotachylyte by Ancient Seismic Faulting
Summary Pseudotachylyte occurs as vein material infilling highly brittle shear and extensional fractures developed along the western margin of the late Caledonian, Outer Hebrides Thrust zone in NWExpand

A note on fault reactivation
Reactivation of existing faults whose normal lies in the σ1′σ3′ plane of a stress field with effective principal compressive stresses σ1′ >σ2′ >σ3′ is considered for the simplest frictional failureExpand

Structural permeability of fluid-driven fault-fracture meshes
Fluid redistribution in the crust is influenced by hydraulic gradient, by existing permeability anisotropy arising from bedding and other forms of layering, and by structural permeability developedExpand

Thickness of the Seismic Slip Zone
This article reviews geologic and other evidence constraining the thickness of the principal slip zone (PSZ) that accommodates the bulk of coseismic shear displacement during an individual ruptureExpand

High-angle reverse faults, fluid-pressure cycling, and mesothermal gold-quartz deposits
Many mesothermal gold-quartz deposits are localized along high-angle reverse or reverse-oblique shear zones within greenstone belt terrains. Characteristically, these fault-hosted vein depositsExpand

Brecciation processes in fault zones: Inferences from earthquake rupturing
Surface-rupture patterns and aftershock distributions accompanying moderate to large shallow earthquakes reveal a residual brittle infrastructure for established crustal fault zones, the complexityExpand

Earthquake faulting as a structural process
Abstract Structural geology is concerned with the history of movement in the Earth's crust and the processes by which displacements occur. In the upper one third to one half of deforming continentalExpand

Conditions for fault-valve behaviour
  • R. Sibson
  • Geology
  • Geological Society, London, Special Publications
  • 1990
Abstract Evidence for fluid pressures well in excess of hydrostatic during crustal deformation is provided by direct measurements of pressure levels in active tectonic regions and by hydrothermalExpand
