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
Gondwana resulted in the Uralian orogeny and Laurasia. Pangaea was finally amalgamated in the Late Carboniferous-Early Permian, but the oblique forces continued until Pangaea began to rift in the Triassic. In the eastern end collisions occurred slightly later. The North China, South China, and Indochina blocks rifted from Gondwana during the middle Paleozoic and opened the Proto-Tethys Ocean. North China docked with Mongolia and Siberia during the Carboniferous–Permian, followed by South China. The Cimmerian blocks then rifted from Gondwana to form the Palaeo-Thethys and Neo-Tethys oceans in the Late Carboniferous, and docked with Asia during the Triassic and Jurassic. Western Pangaea
