Granular Packings and Fault Zones

Physical Review Letters, 2000
The failure of a two-dimensional packing of elastic grains is analyzed using a numerical model. The packing fails through formation of shear bands or faults. During failure there is a separation of the system into two grain-packing states. In a shear band, local "rotating bearings" are spontaneously formed.

Facies Modelling in Fault Zones

ECMOR X - 10th European Conference on the Mathematics of Oil Recovery, 2006
Traditionally fault impact on fluid flow is included by assigning transmissibility multipliers to flow simulation grid cell faces co-located with the fault plane (Manzocchi et al. 1999). A new method, called Fault Facies modelling (Tveranger et al. 2004, 2005), captures fault impact by considering faults as deformed rock volumes rather than simple ...

Flow Through Inhomogeneous Fault Zones

Proceedings of SPE Annual Technical Conference and Exhibition, 2007
Abstract Faults significantly influence fluid flow in reservoirs. In standard reservoir flow-simulator grids, faults are represented as surfaces or planes. However, outcrop studies show that faults often must be regarded as volumetric elements.

Fault zone analysis: identifying motor defects using the rotor fault zone

Proceedings Electrical Insulation Conference and Electrical Manufacturing Expo, 2005., 2006
In the last decade, advancements in motor testing technology have brought forth advances in online and offline testing. Online current signature analysis (CSA) is quickly becoming a standard industry practice. Offline tests include advanced inductance measurements to analyze rotor and stator health.

Fault Core/damage Zone; an Unhelpful Description of Fault Zone Structure?

Proceedings, 2012
The standard outcrop description of fault zones currently in vogue is a high strain fault core containing fault rock surrounded by a low strain halo termed a damage zone. This description does not acknowledge the significance of fault segmentation or displacement partitioning within fault zones and therefore fails to capture features which are crucial ...

Oceanic fault zones reconstructed

Nature, 2021
Tectonic-plate material is generally thought to be neither created nor destroyed at plate boundaries called oceanic transform faults. An analysis of sea-floor topography suggests that this assumption is incorrect. Crustal thinning and regrowth at oceanic transform faults.

Relating Fault Mechanics to Fault Zone Structure

2004
Abstract The fault zone of a mature large-displacement fault may be idealized as a nested hierarchical structure consisting of a core of extremely fine grained material surrounded by coarser granulated gouge and breccia which is in turn bordered by fracture-damaged wall rock in which the fracture density decreases with distance to a regional ...

Fault-zone weakening processes along the reactivated Outer Hebrides Fault Zone, Scotland

Journal of the Geological Society, 1997
The Outer Hebrides Fault Zone is a major reactivated structure cutting amphibolite-grade Lewisian basement gneisses in NW Scotland. During a regionally important phase of sinistral strike-slip movements, the influx of chemically active hydrous fluids along the fault zone was associated with the formation of a network of greenschist-facies phyllonitic ...
