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 ...
Strike-slip faults are commonly almost vertically inclined faults, where the main displacement and slip is in the horizontal direction, parallel to the strike of the fault. Depending on the movement of the fault blocks relative to the fault plane, strike-slip faults can be classified as either sinistral (left-lateral displacement) or dextral ...
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]
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 ...
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 ...
In geology, a basin is a region where subsidence generates accommodation space for the deposition of sediments. A pull-apart basin is a structural basin where two overlapping (en echelon) strike-slip faults or a fault bend create an area of crustal extension undergoing tension, which causes the basin to sink down.
The Mendocino Fault Zone, the region responsible for the quake, is home to strike-slip faults, which involve horizontal motion rather than vertical displacement that would typically move larger ...
Diagram of fault geometry (in map view) that leads to transtension at the bend or step-over. Releasing bends are transtensional structures that form where the orientation of a strike-slip fault becomes oblique to the regional slip vector causing local extension (such as a right stepping bend on a right-lateral fault).
