In geology, a terrane (/ t ə ˈ r eɪ n, ˈ t ɛr eɪ n /; [1] [2] in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or "sutured" to crust lying on another plate. The crustal block or fragment preserves its distinctive geologic history, which is different from the ...
Terrain (from Latin: terra 'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography , terrain is the lay of the land. This is usually expressed in terms of the elevation , slope , and orientation of terrain features.
The GMC Terrain is a crossover SUV by American manufacturer General Motors under its GMC marque. Sharing its platform with the Chevrolet Equinox , the first-generation Terrain was built on GM's Theta platform , [ 1 ] while subsequent generations are built on the Delta platform .
Badlands – Type of heavily eroded terrain; Bornhardt – A large dome-shaped, steep-sided, bald rock; Butte – Isolated hill with steep, often vertical sides and a small, relatively flat top; Canyon – Deep chasm between cliffs; Cave – Natural void under the Earth's surface; Cirque – An amphitheatre-like valley formed by glacial erosion
In the Carboniferous, the new continent and another terrane, Armorica which included Iberia, drifted in from Gondwana, trapping Avalonia between it and the continent so adding Iberia/Armorica to Euramerica. [13] This was followed up by the arrival of Gondwana. The effects of these collisions are seen in Europe as the Variscan folding. In North ...
The Yakutat Terrane is currently colliding with the continental margin below the central Gulf of Alaska. During the Neogene the terrane's western part was subducted after which a sediment wedge accreted along the northeast Aleutian Trench. This wedge incorporates sediment eroded from the continental margin and marine sediments carried into the ...

Oceanic-continental convergence and creation of accretionary wedge Stages of accretion through time with accretionary wedge and volcanic island arc. In geology, accretion is a process by which material is added to a tectonic plate at a subduction zone, frequently on the edge of existing continental landmasses.
