Siberia (continent) the Carboniferous Period, it collided with the minor continent of Kazakhstania. A subsequent collision with Baltica during the Permian completed the formation of the supercontinent Pangaea. The Siberian Traps formed. Pangaea split up during the Jurassic though Siberia stayed with Laurasia. Laurasia gradually split up during the Cretaceous with Siberia remaining part of present-day northeastern Eurasia. Today, Siberia forms part of the minor supercontinent of Afro-Eurasia. In around 250 million years from now Siberia may be in the subtropical region and part of a new supercontinent of Pangaea Ultima. Siberia (continent) Siberia, also known as Angaraland (or simply Angara) and
Geology of England Permian, the new continent and another terrane, Armorica which included Iberia, drifted in from Gondwana, trapping Avalonia between it and the continent so adding Iberia/Armorica to Euramerica. This was followed up by the arrival of Gondwana. The effects of these collisions are seen in Europe as the Variscan folding. In North America it shows as later phases of the Acadian orogeny. This was happening at around the Equator during the later Carboniferous, forming Pangaea in such a way that Avalonia was near its centre but partially flooded by shallow sea. In the Jurassic, Pangaea split into Laurasia and Gondwana, with
