Dating of the Karakorum Strike‐slip Fault

Acta Geologica Sinica - English Edition, 2001
AbstractThis paper mainly discusses the timing of the Karakorum strike‐slip fault, and gives a brief introduction of its structures, offset, and deformational style. This fault strikes NNW‐SSE. Asymmetrical folds, stretching lineation, S‐C fabrics, feldspar and quartz s̀‐porphyroclasts, domino structure, shear cleavages and faults in the fault zone are

Sidewall ripouts in strike-slip faults

Journal of Structural Geology, 1989
Abstract Distinctive splay fault configurations in wallrocks associated with pseudotachylyte-bearing strike-slip fault structures at three different localities are recognized as ‘sidewall ripouts’. Sidewall ripout structures occur as asymmetric, doubly-tapered, fault-bounded lenses or slabs adjacent to a dominant planar fault surface.

Sinuosity of strike-slip fault traces

Geology, 1975
A mechanical basis for the occurrence of curvature or sinuosity on strike-slip faults is postulated from finite-element simulation of an earthquake sequence on the Parkfield, California, segment of the San Andreas fault. Using discontinuity fields from measured displacements associated with the M ≅ 5.3 earthquakes of June 1966, motions along 16 km of ...

Volcanism in Reverse and Strike-Slip Fault Settings

2009
Traditionally volcanism is thought to require an extensional state of stress in the crust. This review examines recent relevant data demonstrating that volcanism occurs also in compressional tectonic settings associated with reverse and strike-slip faulting.

Strike-Slip Faults of Northern Venezuela

AAPG Bulletin, 1956
The Caribbean Mountains of northern Venezuela, and the area covered by the Caribbean Sea off the coast of Venezuela have been displaced to the east, relative to the land on the south, along a system of major strike-slip faults. From west to east this right-lateral fracture system consists of the following big faults: the Ocoa fault in the northern ...

A stochastic model for strike-slip faulting

Journal of the International Association for Mathematical Geology, 1980
The frequency of length of strike-slip faults in continental crust follows a lognormal probability distribution, and a nonlinear positive correlation exists between length and offset. These results appear to be scale-independent. An explanation of the observations is presented in terms of a stochastic model which treats the occurrence of faulting as a ...

Mechanics of strike-slip faulting with friction

Journal of Geophysical Research, 1968
Strike-slip is analyzed for long, shallow surface faults of arbitrary dip on which motion is opposed by a frictional shear stress, which is assumed to increase linearly with depth. Static elastic analysis is used to find surface displacements and strains and to estimate the change in elastic potential energy, the frictional dissipation, and the ...

Some theoretical implications of strike-slip faulting

2011
When a fault occurs in the earth's crust, the ground in its vicinity becomes deformed. This thesis uses the theory of dislocations, as developed by J. A. Steketee, to examine the nature of this deformation for a variety of strike-slip fault models. The theory is developed for calculating the displacement field and stress changes expected at any point ...
