The following is a list of known orogenies organised by continent, starting with the oldest in each. The headings are present-day continents, which may differ from the geography contemporary to the orogenies. Some orogenies encompass more than one continent and may have different names in each, and some very large orogenies include sub-orogenies.

A similar sequence of orogenies has taken place on the west coast of North America, beginning in the late Devonian (about 380 million years ago) with the Antler orogeny and continuing with the Sonoma orogeny and Sevier orogeny and culminating with the Laramide orogeny. The Laramide orogeny alone lasted 40 million years, from 75 million to 35 ...
The Mazatzal orogeny was an orogenic event in what is now the Southwestern United States from 1650 to 1600 Mya [1] in the Statherian Period of the Paleoproterozoic. Preserved in the rocks of New Mexico and Arizona , it is interpreted as the collision of the 1700-1600 Mya age [ 1 ] Mazatzal island arc terrane with the proto-North American continent.
The Nevadan Orogeny began with the formation of a continental volcanic arc due to east dipping subduction of the Farallon Plate beneath the North American Plate. [1] Continued subduction of oceanic crust transported multiple oceanic arc terranes to the western margin of North America where they were accreted onto the edge of the continent. [1]
The Laramide orogeny was a time period of mountain building in western North America, which started in the Late Cretaceous, 80 to 70 million years ago, and ended 55 to 35 million years ago. The exact duration and ages of beginning and end of the orogeny are in dispute.
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.
The Acadian orogeny is a long-lasting mountain building event which began in the Middle Devonian, reaching a climax in the Late Devonian. [1] It was active for approximately 50 million years, beginning roughly around 375 million years ago (Ma), with deformational, plutonic, and metamorphic events extending into the early Mississippian.
