Recent geodynamics of fault zones: faulting in real time scale

Geodynamics & Tectonophysics, 2014
Recent deformation processes taking place in real time are analyzed on the basis of data on fault zones which were collected by long-term detailed geodetic survey studies with application of field methods and satellite monitoring.A new category of recent crustal movements is described and termed as parametrically induced tectonic strain in fault zones.

Fault zone fabric and fault weakness

Nature, 2009
Geological and geophysical evidence suggests that some crustal faults are weak compared to laboratory measurements of frictional strength. Explanations for fault weakness include the presence of weak minerals, high fluid pressures within the fault core and dynamic processes such as normal stress reduction, acoustic fluidization or extreme weakening at ...

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.

Fault zones: A complex issue

Journal of Structural Geology, 2010
Faults are complex 4-D structures: volumes of complexly deformed rock that evolve in their structural and fluid flow properties through time.

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 ...

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 ...

Discontinuous fault zones

Journal of Structural Geology, 1987
Abstract Many tectonic faults and tension fractures are, at least initially, composed of separate segments. This note deals with a little explored reason for this phenomenon which, in faulting, has obvious implications both for the migration of hydrocarbons and for the sealing capacity of faults. Theoretical arguments based on CoulombMohr's theory of
