List of orogenies

The following is a list of known orogenies organised by continent, starting with the oldest at the top. The organization of this article is along present-day continents that do not necessarily reflect the geography contemporary to the orogenies. Note that some orogenies encompass more than one continent and might have different names in each continent. Likewise some very large orogenies include a number of sub-orogenies. As with other geological phenomena orogenies are often subject to different and changing interpretations regarding to their age, type and associated paleogeography. In some interpretations, especially in the older literature, the term orogeny is equivalent to a long "Episode" of basin formation and deposition of sediments (with durations of hundreds of millions of years), ending with deformation (sometimes including metamorphism) of these deposits. Some workers use the term only for the final mountain building deformation "Event" with a small duration of tens of millions of years or even shorter. [1] [2]

Orogenies affecting Antarctica include:[3]

Asian orogenies

Persia–Tibet–Burma orogeny in Eurasian Plate

European orogenies

  • Saamian orogeny – Formation of an extensive area of tonalitic-trondhjemitic crust in Fennoscandia, (3.1–2.9 Ga)
  • Lopian orogeny – Archean orogeny – Formation of two different types of terrain compatible with plate tectonic concepts. One is a belt of high-grade gneisses formed in a regime of strong mobility, while the other is a region of granitoid intrusions and greenstone belts surrounded by the remnants of a Saamian substratum, (2.9–2.6 Ga)
  • Svecofennian orogeny, also known as Svecokarelian orogeny – Geological process that resulted in formation of continental crust in Sweden, Finland and Russia, (2.0–1.75 Ga)
  • Gothian orogeny – Formation of tonalitic-granodioritic plutonic rocks and calc-alkaline volcanites (like the previous Svecofennian orogeny), (1.75–1.5 Ga)
  • Sveconorwegian orogeny – Orogenic belt in southwestern Sweden and southern Norway – Essentially reworking of previously formed crust, (1.25 Ga – 900 Ma)
  • Timanide orogeny – Orogen that formed during the Neoproterozoic – Affecting the northern Baltic Shield during the Neoproterozoic Era, (620–550 Ma)
  • Cadomian orogeny – On the north coast of Armorica in the Ediacaran/Cambrian, (660–540 Ma)
  • Caledonian orogeny – Mountain building event caused by the collision of Laurentia, Baltica and Avalonia – Deformation of the western Scandinavian Peninsula, Britain and Ireland, in the Ordovician Grampian phase and the Silurian Scandian phase[4]
  • Variscan orogeny, also known as Hercynian orogeny – Collision of tectonic plates resulting in the creation of mountains – Deformation in western Iberia, southwest Ireland, southwest England, central and western France, southern Germany and Czech Republic, during the Devonian and Carboniferous Periods
  • Uralian orogeny – Long series of linear deformation and mountain building events that raised the Ural Mountains, during the Permian Period.
  • Alpine orogeny – Formation of the Alpine mountain ranges of Europe, the Middle East and northwest Africa, encompassing:
  • Mediterranean Ridge – Seabed ridge south of Greece

North American orogenies

Taconic orogeny

Oceania orogenies

Australian orogenies

New Zealand orogenies

  • Tuhua Orogeny, (370–330 Ma)
  • Rangitata Orogeny – long period of uplift and collision in New Zealand, (142–99 Ma)
  • Kaikoura Orogeny – seismic formation event, (24 Ma – present)

South American orogenies
