Summary

Description
English: An illustration of the collision between two tectonic plates. One plate goes under the other, and the result is the buildup of a critical wedge of material. This orogenic wedge, or mountain-building wedge, maintains its slope by a stress balance between failures along the décollment, or main basal fault, and the faults inside the wedge.

This geology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Orogenic wedge.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
