Orogeny is a geologic term associated with periods of mountain building. An orogenic belt, therefore, is a geologic structure associated with continental collisions and mountain building. Generally orogenic belts consist of long parallel strips of rock exhibiting similar characteristics along the length of the belt. The details of the specific belt will vary with what collided and the details of the collision. Frequently, many of the rock formations involved in the collision (Orogeny) will be severely deformed and metamorphosed. During this process, deeply buried rocks may be pushed to the surface. Sea bottom and near shore material may be overthrust into the orogeny covering some or all of the active area. Someplace under the orogenic belt will be a subduction zone that promoted the collision by consuming crust and dragging the material on one side of the collision into contact with that on the other. The subduction zone may have volcanoes or lava flows associated with it. 1 List of orogenies
- Acadian orogeny ( E. US) during Silurian and Devonian time.
- Alpine orogeny Formation of the Alps during Eocene through Miocene time.
- Andean orogeny ( Andes, 0-200 Myr ago)
- Antler orogeny (ancestral Sierra Nevada)
- Appalachian orogeny ( Appalachian MountainsThe Appalachian Mountains are a system of North American mountains running from Newfoundland and Labrador, Canada to Alabama in the United States, although the northernmost mainland portion ends at the Gaspe Peninsula of Quebec. The system is divided into, ) is a well studied orogenic belt resulting from a late paleozoic collision between North America and Africa. It stretches for many hundreds of miles on the surface from AlabamaAlabama is a state located in the southern United States; the population of Alabama is 4,447,100 as of 2000. The USS Alabama and CSS Alabama were named in honor of this state. History Main article: History of Alabama Among Native American people once livi to New JerseyNew Jersey is a state of the United States of America and has the U. postal abbreviation of NJ . The state is named after the island of Jersey in the English Channel. The USS New Jersey one of the most decorated vessels in the United States Navy, was name and can be traced further subsurface to the southwest. In the north it enters a region of confused topography associated with earlier orogenies, but clearly the Applachian deformations extend North to LabradorThis article is about the region in Canada.

- Caledonian orogeny (between Europe and Greenland) in Silurian time.
- Carpathean orogeny : Carpathian MountainsThis article is about the terrestrial mountain range. There is also a range on the Moon called the Carpathian Mountains (Moon). The Carpathian Mountains are the eastern wing of the great central mountain system of Europe curving 1500 km (~900 miles) along of east Europe during the Miocene
- The Cimmerian and Cathayasian orogenies were active through TriassicThe Triassic is a Geologic period that extends from about 248 to 202 million years (My or 'megayears') before the present. The extinction event that closed the Triassic period has recently been more accurately dated, but as with most older geologic period and JurassicThe Jurassic period is a major unit of the geologic timescale that extends from about 135 million years BP at the end of the Triassic to 195 million years BP at the beginning of the Cretaceous. As with other geologic periods, the rock beds that define the along south and southeast Asia.
- Granville orogeny
- Hellenic orogeny Greece and Aegean area during Eocene through Miocene time.
- Himalayan orogeny ( Himalaya Mountains) is a result of the ongoing collision of the Indian Plate with the Eurasian Plate.
- Laramide orogeny ( Rocky Mountains, 40-70 Myr ago)
- Nevadan orogeny was developing along western North America during the Jurassic.
- Ouachita orogeny ( Ouachita Mountains) of Arkansas and Oklahoma is an orogenic belt that dates from the late Paleozoic and is most likely a continuation of the Appalachian orogeny west across the Mississippi embayment rift zone .
- Taconic Orogeny (NE US and Canada) during Ordovician time.
- Ural orogeny in Eurasia during Permian time.
- Variscan orogeny
