Laurasia and Gondwana were equal in size but had distinct geological histories. Gondwana was assembled before the formation of Pangaea, but the assembly of Laurasia occurred during and after the formation of the supercontinent. These differences resulted in different patterns of basin formation and transport of sediments.
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 "Old Red Continent" formed by the Caledonian Orogeny, joined with Gondwana to form Pangaea [18] Mawson: 1730 Paleoproterozoic Continent [3] Nena: 1900 Paleoproterozoic Continent [13] North Australia: 2000 Paleoproterozoic Craton [19] North China: 2500 Paleoproterozoic Craton [1] [4] Pangaea: 350 Late Permian Supercontinent [15] Pannotia ...
Comparison of the paleomagnetic poles of Patagonia and Gondwana from the Devonian to Permian periods allows for the separation of the two landmasses by up to 1000 kilometres; [4] however, though such a separation is permitted by the evidence, it is not required in order to explain differences in the pole positions. [12]
Pangaea's supercontinent cycle is a good example of the efficiency of using the presence or lack of these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.
Per USA Today, Gondwana, a former supercontinent, broke off from the landmass of Pangea about 180 million years ago and included multiple other continents including South America, Africa ...
Formed as Gondwana broke up Pliensbachian: 190.8 ± 1.0 * Sinemurian: 199.3 ± 0.3 * C. Atlantic magmatic province (Recurrent)(197±1) [x] Hettangian: 201.3 ± 0.2 * Central Atlantic magmatic province (199.5±0.5) [x] Formed as Pangea broke up Triassic–Jurassic extinction event: Triassic: Upper: Rhaetian: c. 208.5 Norian: c. 228 Wrangellia ...
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 ...
