The role of off-fault damage in the evolution of normal faults

Earth and Planetary Science Letters, 2004
Abstract Recent measurements of slip profiles on normal faults have found that they are usually triangular in shape. This has been explained to be a consequence of on-fault processes such as slip-dependent friction. However, the recent observation that cumulative slip profiles on normal faults and fault systems in Afar are both triangular and self ...

Normal fault growth, displacement localisation and the evolution of normal fault populations: the Hammam Faraun fault block, Suez rift, Egypt

Journal of Structural Geology, 2003
Fault segment linkage, migration of the locus of fault activity, and displacement localisation were important processes controlling the late Oligocene-Recent evolution of the normal fault population of the Hammam Faraun fault block, Suez rift. Initial fault activity was distributed across the fault block on fault segments that had attained their final ...

Normal fault corrugation: implications for growth and seismicity of active normal faults

Journal of Structural Geology, 1999
Abstract Large normal faults are corrugated. Corrugations appear to form from overlapping or en echelon fault arrays by two breakthrough mechanisms: lateral propagation of curved fault-tips and linkage by connecting faults. Both mechanisms include localized fault-parallel extension and eventual abandonment of relay ramps.

The geometry of normal faults

Journal of the Geological Society, 1990
This meeting took place at Burlington House on 14 and 15 June 1989. Until recently a specialist structural geology meeting on a theme such as this would have been solely the preserve of the Tectonic Studies Group.

Normal faults, normal friction?

Geology, 2001
Debate continues as to whether normal faults may be seismically active at very low dips (d , 308) in the upper continental crust. An updated compilation of dip estimates (n 5 25) has been prepared from focal mechanisms of shallow, intracontinental, normal-slip earthquakes (M .

Dilational normal faults

Journal of Structural Geology, 2003
Abstract At low differential effective stress and with minimum principal effective stress near zero or tensile, rocks fail in several modes and with variable failure angles. Under these conditions mechanical stratigraphy exerts a significant influence on initial dip of normal faults.

Overlapping Faults, Intrabasin Highs, and the Growth of Normal Faults

The Journal of Geology, 1994
Normal fault systems bounding extensional basins are typically adjoined by a series of subbasins separated by intrabasin highs. The strata within these basins form syndepositional anticlines and synclines whose axes are transverse to the strike of the main bounding fault.

Fault reactivation control on normal fault growth: an experimental study

Journal of Structural Geology, 2005
Field studies frequently emphasize how fault reactivation is involved in the deformation of the upper crust. However, this phenomenon is generally neglected (except in inversion models) in analogue and numerical models performed to study fault network growth.
