Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
Animation of the break-up of the supercontinent Pangaea and the subsequent drift of its constituents, from the Early Triassic to recent (250 Ma to 0). This is a list of paleocontinents, significant landmasses that have been proposed to exist in the geological past. The degree of certainty to which the identified landmasses can be regarded as ...
First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana.. The Tethys Ocean (/ ˈ t iː θ ɪ s, ˈ t ɛ-/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early-mid Cenozoic Era.
Map of Earth during the Early Permian, around 285 million years ago, showing Central Pangean mountain range at equator. The Central Pangean Mountains were formed during the collision of Euramerica and northern Gondwana as part of the Variscan and Alleghanian orogenies, which began during the Carboniferous approximately 340 million years ago, and complete by the beginning of the Permian around ...
Pangaea was finally amalgamated in the Late Carboniferous-Early Permian, but the oblique forces continued until Pangaea began to rift in the Triassic. [33] 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 ...
The Pangean megamonsoon refers to the theory that the supercontinent Pangea experienced a distinct seasonal reversal of winds, which resulted in extreme transitions between dry and wet periods throughout the year. Pangea was a conglomeration of all the global continental land masses, which lasted from the late Carboniferous to the mid-Jurassic. [1]
East Antarctica was the highest ground within Pangaea and produced sediments that were transported across eastern Gondwana but never reached Laurasia. During the Palaeozoic, c. 30–40% of Laurasia was covered by shallow marine water but only 10–20% of Gondwana was covered by shallow marine water.
The eastern part of this ocean formed between Baltica and Laurentia, the western part between Amazonia and Laurentia. Because the timeframe of this separation and the partially contemporaneous Pan-African orogeny are difficult to correlate, it might be that all continental mass was again joined in one supercontinent between roughly 600 and 550 Ma.
