Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges .
The Apennine orogeny is a type of mountain-building in which two simpler types are combined in an apparently paradoxical configuration. Sometimes this is referred to as "syn-orogenic extension", but the term implies that the two processes occur simultaneously during time.
Taconic orogeny. Algoman orogeny, also known as Kenoran orogeny – Late Archaean episode of mountain building in what is now North America – Superior province, South Dakota to Lake Huron, late Archean Eon (2700–2500 Ma) Wopmay orogeny – Mountain-building event in northern Canada – Along western edge of Canadian shield, (2100–1900 Ma)
The Alleghanian orogeny, a result of three separate continental collisions. USGS. The immense region involved in the continental collision, the vast temporal length of the orogeny, and the thickness of the pile of sediments and igneous rocks known to have been involved are evidence that at the peak of the mountain-building process, the Appalachians likely once reached elevations similar to ...
The Grenville orogeny was a long-lived Mesoproterozoic mountain-building event associated with the assembly of the supercontinent Rodinia. Its record is a prominent orogenic belt which spans a significant portion of the North American continent, from Labrador to Mexico , as well as to Scotland .
The Sevier Fold and Thrust Belt extends from southern California near the Mexican border to Canada. [1] Basin and Range faults cut the older Sevier thrust faults. [4] The Sevier orogeny was preceded by several other mountain-building events including the Nevadan orogeny, the Sonoman orogeny, and the Antler orogeny, and partially overlapped in time and space with the Laramide orogeny.
