Thrust tectonics or contractional tectonics is concerned with the structures formed by, and the tectonic processes associated with, the shortening and thickening of the crust or lithosphere. It is one of the three main types of tectonic regime, the others being extensional tectonics and strike-slip tectonics .

In geology, a nappe or thrust sheet is a large sheetlike body of rock that has been moved more than 2 km (1.2 mi) [1] or 5 km (3.1 mi) [2] [3] above a thrust fault from its original position. Nappes form in compressional tectonic settings like continental collision zones or on the overriding plate in active subduction zones.
The use of more complex compression machines substantially increases the number of simulations of compressional tectonics, including subduction, collision, lithospheric shortening, fracture formation, thrust and accretionary wedge. If the simulation only focuses on the upper crustal, the model is always built in the glass box (or two lateral ...
A fold and thrust belt (FTB) is a series of mountainous foothills adjacent to an orogenic belt, which forms due to contractional tectonics. Fold and thrust belts commonly form in the forelands adjacent to major orogens as deformation propagates outwards. Fold and thrust belts usually comprise both folds and thrust faults, commonly interrelated ...
Knowledge of the kinematics of the Himalayan fault system is not as ideal as it has long been debated. To help understand the structural position the Main Central Thrust and role it played in the tectonic evolution of Himalaya, there are three general kinematic models: extrusion model, [11] channel flow model, [12] tectonic wedging model.
Schematic overview of a thrust system. The hanging wall block is (when it has reasonable proportions) called a nappe which overlays the autochthonous (unrelocated) material. A hole in the nappe which exposes the underlying autochthonous material is called a window. A klippe is a solitary outcrop of the nappe in the middle of autochthonous material.
For this reason the area in which the thrust is found was declared a geotope, a geologic UNESCO World Heritage Site, under the name "Swiss Tectonic Arena Sardona." The area of this "tectonic arena" encompasses 32,850 hectares of mainly mountainous landscape in 19 communities between the Surselva, Linthtal and Walensee.
