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.
