A oroxenia caledoniana comprende sucesos que ocorreron desde o [[Ordovícico]] ao [[Devónico]] temperán, aproximadamente hai de 490 a 390 millóns de anos (Ma). Foi causada polo peche do antigo [[océano de Iapetus]] cando chocaron os continentes e os [[terreo]]s de [[Laurentia]], [[Báltica]] e [[Avalonia]]. Present day coastlines are indicated in gray for reference. Later in [[Geological history of the Earth\|geological history]], the [[Atlantic Ocean]] opened and the different parts of the orogenic belt moved apart.<ref>Reconstruction based on Matte (2001); Stampfli ''et al.''

The Caledonian orogeny encompasses events that occurred from the [[Ordovician]] to Early [[Devonian]], roughly 490–390 million years ago ([[Megaannum\|Ma]]). It was caused by the closure of the [[Iapetus Ocean]] when the continents and [[terrane]]s of [[Laurentia]], [[Baltica]] and [[Avalonia]] collided. The Caledonian orogeny is named for [[Caledonia]], the [[Latin]] name for [[Scotland]]. The name was first used in 1885 by [[Austria]]n geologist [[Eduard Suess]] for an episode of mountain building in northern Europe that predated the [[Devonian]] [[period (geology)\|period]]. Geologists like [[Émile Haug]] and [[Hans Stille]] saw the Caledonian orogeny as one of several episodic phases of mountain building that had occurred during [[History of Earth\|Earth's history]].<ref>McKerrow ''et al.'' (2002)</ref> Current understanding has it that the Caledonian orogeny encompasses a number of [[Tectonics\|tectonic]] phases that can laterally be [[diachronous]]. The name "Caledonian" can therefore not be used for an absolute period of geological time, it applies only to a series of tectonically related events. == Historia xeodinámica == ▲<!-- The Caledonian orogeny was one of several [[orogeny\|orogenies]] that would eventually form the [[supercontinent]] [[Pangaea]] in the Late [[Paleozoic]] [[era]]. In the Early Paleozoic the majority of all continental landmasses were united in the [[paleocontinent]] of [[Gondwana]], containing the crust of future [[Africa]], [[South America]], southern [[Eurasia]], [[Australia]] and [[Antarctica]], which lay centered on the South Pole. Between 650 and 550 million years ago (in the [[Ediacaran]] period) the smaller continents of Laurentia (containing the future northeast section of [[North America]]), [[Baltica]] and [[Siberia]] had separated from Gondwana to move northward towards the equator. In the process, the [[Iapetus Ocean]] between Gondwana, Baltica and Laurentia closed.
