Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists. Origin of the concept. Alfred Wegener c. 1924–1930World map of Pangaea created by Alfred Wegener to illustrate his concept. The name "Pangaea" is derived from Ancient Greekpan(πᾶν, "all, entire, whole") and Gaiaor Gaea (Γαῖα ...
The opening of the North Atlantic Ocean is a geological event that has occurred over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe (Eurasian Plate) and North America (North American Plate) separated during the final breakup of Pangea in the early Cenozoic Era, [ 1 ] they formed the North Atlantic Ocean.
Laurasia (/ l ɔː ˈ r eɪ ʒ ə,-ʃ i ə /) [1] was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around , the other being Gondwana. It separated from Gondwana 215 to 175 Mya (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split and finally ...
Formed from three cratonic fragments - the Baltic Shield, Sarmatia and Volgo–Uralia. Formed part of Columbia, then Rodinia and Pannotia. Collided with Laurentia and Avalonia to form Laurussia. [1][4][2][10] Cathaysia. 1800. Continent. Fused with the Yangtze block to form the South China Craton during the Early Paleozoic.
Gondwana formed part of Pangaea for c. 150 Ma [31] Gondwana and Laurasia formed the Pangaea supercontinent during the Carboniferous. Pangaea began to break up in the Mid-Jurassic when the Central Atlantic opened. [32] In the western end of Pangaea, the collision between Gondwana and Laurasia closed the Rheic and Palaeo-Tethys oceans.
The continents formed at the break-up of Pannotia and Rodinia at the end of the Proterozoic slowly moved together again, forming the supercontinent Pangaea in the late Paleozoic. [ 148 ] The Mesozoic ("middle life") era lasted from 251.9 Ma to 66 Ma. [ 105 ]
Pangaea Proxima (also called Pangaea Ultima, Neopangaea, and Pangaea II) is a possible future supercontinent configuration. Consistent with the supercontinent cycle, Pangaea Proxima could form within the next 250 million years. This potential configuration, hypothesized by Christopher Scotese in November 1982, earned its name from its ...
The supercontinent Pangaea in the early Mesozoic (at 200 Ma) surrounded by Panthalassa. The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago. Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [ 1 ...
