The geometry and dimensions of fault-core lenses
Geological Society, London, Special Publications, 2016AbstractField analysis shows that fault cores of brittle, extensional faults at a medium to mature stage of development are commonly dominated by lozenge-shaped horses (fault-core lenses) characterized by a variety of lithologies, including intact, mildly to strongly deformed country rock derived from the footwalls and hanging walls, various types of ...

Effects of layering and anisotropy on fault geometry
Journal of the Geological Society, 1992The geometry and orientation of faults are examined using several field examples of small-scale (< lm displacement) fault systems. For isotropic rocks under triaxial compression, faults normally develop in conjugate sets about the maximum compressive stress (σ 1 ), with dihedral angles usually of about 50°, as ...

Analogue models of extensional fault geometries
Geological Society, London, Special Publications, 1987Summary The progressive development of extensional fault geometries in a sedimentary cover sequence above a rigid or deforming basement has been experimentally investigated using analogue models. Quartz sand (700 μm) was used as a modelling material.

Analysis of fault geometry and displacement patterns
Geological Society, London, Special Publications, 1996Abstract Interpretation of the subsurface is still often performed on suites of vertical seismic sections with structures being correlated from line to line to build up a map view at a particular horizon. The advent of 3D seismic surveys and routine use of interpretation software has made it common to produce ‘horizon-based’ interpretations ...

Fault geometry and earthquakes in continental interiors
Tectonophysics, 1999Abstract Although large earthquakes in continental interiors are much less frequent than those along plate boundaries, they have been responsible for a disproportionate amount of destruction. I present a testable model for strain accumulation and seismicity in the upper crust of continental interiors.

Geometry of Shearing Stress and Relation to Faulting
The Journal of Geology, 1951The distributions of intensity and orientation of maximum shearing stress in typical stress systems are plotted on stereographic projections in order to show the three-dimensional relationships. Mathematical expressions of these relationships as well as graphical methods of evaluation are given.

Fault-network geometry influences earthquake frictional behaviour
NatureUnderstanding the factors governing the stability of fault slip is a crucial problem in fault mechanics1-3. The importance of fault geometry and roughness on fault-slip behaviour has been highlighted in recent lab experiments4-7 and numerical models8-11, and emerging evidence suggests that large-scale complexities in fault networks have a vital role in
