accretionary wedge

The belt is the accretionary wedge of the Carpathians.

A mélange is formed in the accretionary wedge above a subduction zone.

The range is a combined horst, forearc high and accretionary wedge structure.

The internal structure of an accretionary wedge is similar to that found in a thin-skinned foreland thrust belt.

In geodynamics the concept is used to explain tectonic observations in accretionary wedges.

Instead, terranes and the accretionary wedge have been uplifted to form a series of coast ranges and exotic mountains.

Materials incorporated in accretionary wedges include:

The Apennines in Italy are largely an accretionary wedge formed as a consequence of subduction.

The Murihiku Terrane is considered to be an accretionary wedge of mainly volcanogenic forearc sediments.

Accretionary wedges and listric faulting are characteristic of plate collisional conditions, and these terms now occur frequently in theses.

In accretionary wedges, seismicity activating superimposed thrusts may drive methane and oil upraising from the upper crust.

These assumptions allow the application of a simple plastic continuum model, which successfully predicts the observed gently convex taper of accretionary wedges.

The mountains themselves are products of accretionary wedge uplifting related to the Juan De Fuca Plate subduction zone.

The paragneiss of the Gotthard nappe was once oceanic sediment, which was deformed into an accretionary wedge during this orogeny.

The Quetico gneiss belt represents an accretionary wedge that formed in a trench during the collision of several island arcs (greenstone belts).

Accretionary wedges in front of subduction zones are normally covered by oceans and the weight of the seawater on top of the wedge can be significant.

The range has no single structural or lithological origin but is the result of the alignment of horst, forearc highs and accretionary wedges along Chile's coast.

Accretionary wedges are the home of mélange, intensely deformed packages of rocks that lack coherent internal layering and coherent internal order.

The Carpathian accretionary wedge is made of several thin skinned nappes composed of Cretaceous to Paleogene turbidites.

The gabbros and peridotites, now lenses in the paragneiss, probably represent pieces of oceanic crust underneath these sediments, that were incorporated into the Ordovician accretionary wedge.

An accretionary prism or accretionary wedge is formed from sediments that are accreted onto the non-subducting tectonic plate at a convergent plate boundary.

Rapid tectonic loading of wet sediment in accretionary wedges is likely to cause the fluid pressure to rise until it is sufficient to cause dilatant fracturing.

Backthrusting of the rear of the accretionary wedge, arcward over the rocks of the forearc basin, is a common aspect of accretionary tectonics.

The Ordenes Massif dates from 380 to 390 Ma, and represents part of the Rheno-Hercynian Ocean as part of an accretionary wedge.

Most tsunami earthquakes have been linked to rupture within the uppermost part of a subduction zone, where an accretionary wedge is developed in the hanging wall of the megathrust.
