An idealized strike-slip fault runs in a straight line with a vertical dip and has only horizontal motion, thus there is no change in topography due to motion of the fault. In reality, as strike-slip faults become large and developed, their behavior changes and becomes more complex. A long strike-slip fault follows a staircase-like trajectory ...
Lateral strike-slip faults. Strike-slip faults occur when the blocks slide against each other laterally, parallel to the plane. The direction of the slip can be observed from either side of the fault, with the far block moving to the left indicating a left lateral slip, and the converse indicating a right lateral slip. See animation here [5]
Magmatism along strike-slip faults is the process of rock melting, magma ascent and emplacement, associated with the tectonics and geometry of various strike-slip settings, most commonly occurring along transform boundaries at mid-ocean ridge spreading centres [1] and at strike-slip systems parallel to oblique subduction zones.

Schematic illustration of the two strike-slip fault types. The view is of the Earth's surface from above. In geology, the terms sinistral and dextral refer to the horizontal component of the movement of blocks on either side of a fault or the sense of movement within a shear zone. These are terms of relative direction, as the movement of the ...
Strike-slip faults with left-lateral motion are also known as sinistral faults and those with right-lateral motion as dextral faults. [18] Each is defined by the direction of movement of the ground as would be seen by an observer on the opposite side of the fault. A special class of strike-slip fault is the transform fault when it forms a plate ...
The East Anatolian Fault is a strike-slip fault. In those, solid rock plates are pushing up against each other across a vertical fault line, building stress until one finally slips in a horizontal ...
Simple model for transpression: strike-slip zone with an additional and simultaneous shortening across the zone. Also induces vertical uplift. In geology, transpression is a type of strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane. This movement ends up ...
In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle ) measured downward from horizontal. [ 1 ]
