Gondwana ( / ɡɒndˈwɑːnə /) [1] was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian Subcontinent. Gondwana was formed by the accretion of several cratons ...
The name is a portmanteau of Laurentia and Asia. [2] Laurentia, Avalonia, Baltica, and a series of smaller terranes, collided in the Caledonian orogeny c. 400 Ma to form Laurussia/Euramerica. Laurussia/Euramerica then collided with Gondwana to form Pangaea. Kazakhstania and Siberia were then added to Pangaea 290–300 Ma to form Laurasia.
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.
The name "Pangaea" is derived from Ancient Greek pan (πᾶν, "all, entire, whole") and Gaia or Gaea (Γαῖα, " Mother Earth, land"). [4][9] The first to suggest that the continents were once joined and later separated may have been Abraham Ortelius in 1596. [10] The concept that the continents once formed a contiguous land mass was ...
Cimmeria (continent) Cimmeria rifted off Gondwana's north-eastern shores around 250 Ma. [1] As Cimmeria migrated from Gondwana to Eurasia the Paleo-Tethys closed and the Neo-Tethys opened. [2] After 150 million years Cimmeria collided with Eurasia and the Cimmerian orogeny closed the Paleo-Tethys. As the break-up of Gondwana began in the south ...
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.
Landscape – Natural. The Gondwana Rainforests of Australia, formerly known as the Central Eastern Rainforest Reserves, are the most extensive area of subtropical rainforest in the world. [1] Collectively, the rainforests are a World Heritage Site with fifty separate reserves totalling 366,500 hectares (906,000 acres) from Newcastle to Brisbane.
1 Relative to the African Plate. The Indian Plate (or India Plate) is a minor tectonic plate straddling the equator in the Eastern Hemisphere. Originally a part of the ancient continent of Gondwana, the Indian Plate broke away from the other fragments of Gondwana 100 million years ago and began moving north, carrying Insular India with it.
