decollement

Due to this pressure a decollement developed over which thrusting took place.

Evaporites are also often related the decollement and thrust planes.

The decollement is also called a detachment fault.

The evaporites served later as major decollement horizons.

This is particularly the case where a good basal decollement exists such as salt or a zone of high pore fluid pressure.

Typical of sedimentary slump folding, migmatites and decollement detachment zones.

Once critical taper is attained, the wedge slides stably along its basal decollement.

Recent geological mapping at the eastern side of the Seattle Fault suggests a decollement (horizontal plane) about 18 km deep.

The phyllite at the granite contact formed a weak horizon, which assisted the decollement process after the batholith was emplaced.

By placing your foot on one end and pushing toward the other, the rug slides across the floor (decollement) and folds upward (detachment fold).

Strata beneath the Upper Triassic halite are unfolded indicating that the salt is acting as a decollement.

The thrust plane itself represents a zone of detachment (or decollement) along a bed of salt or other incompetent lithology.

Furthermore, Pisana et al., 2006, identified protothrusts and decollement surfaces along the Nankai Trough.

Structurally, the Jura consists of a sequence of folds, the formation of which is facilitated by an evaporite decollement layer.

Beneath the inner trench wall, the two plates slide past each other along the subduction decollement, the seafloor intersection of which defines the trench location.

The surface of a thrust fault which caused movement of a nappe is called a decollement, detachment plane or sole of thrust.

Thrusting over the decollement horizon continues today, as the Apulian tectonic plate moves westward, converging with the European plate.

This style may also occur in the foreland where no effective decollement surface is present or where pre-existing extensional rift structures may be inverted.

Eventually the propagating thrust tip may reach another effective decollement layer and a composite fold structure will develop with characteristics of both fault-bend and fault-propagation folds.

From the interpretation of seismic reflection data, it has been proposed that the southeastward displacement takes place on a decollement surface near the top of the oceanic crust.

Typically, you will see repeated sections of the same rock over and over as thrust faults, coming up from the decollement, stack the same layer on top of itself.

Fault-propagation folds form at the tip of a thrust fault where propagation along the decollement has ceased but displacement on the thrust behind the fault tip is continuing.

The shape of the wedge is determined by how readily the wedge will fail along its basal decollement and in its interior; this is highly sensitive to pore fluid pressure.

As is also the case in the southern foreland of the Pyrenees, thrusts in the Southern Alps are oriented along listric fault planes with relatively shallow decollement horizons.

The Jura mountains - A series of sub-parallel mountainous ridges formed by folding over a Triassic evaporite decollement due to thrust movements in the foreland of the Alps.
