Gondwana (/ ɡ ɒ n d ˈ w ɑː n ə /) [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.
The following is a list of known orogenies organised by continent, starting with the oldest in each. The headings are present-day continents, which may differ from the geography contemporary to the orogenies.
The Pan-African orogeny was a series of major Neoproterozoic orogenic events which related to the formation of the supercontinents Gondwana and Pannotia about 600 million years ago. [1] This orogeny is also known as the Pan-Gondwanan or Saldanian Orogeny . [ 2 ]
In another model, the assembly of East Gondwana c. was a multiphase process which included two main periods of orogenesis: the older EAO (c.) and the younger Kuunga Orogeny (c. 6] In the former scenario the Kuunga Orogeny of the latter scenario are two coeval events: the collisions between India and Australia-East Antarctica and Azania and India.
Pannotia was centred on the South Pole, hence its name. Pannotia (from Greek: pan-, "all", -nótos, "south"; meaning "all southern land"), also known as the Vendian supercontinent, Greater Gondwana, and the Pan-African supercontinent, was a relatively short-lived Neoproterozoic supercontinent that formed at the end of the Precambrian during the Pan-African orogeny (650–500 Ma), during the ...
In contrast with Pannotia, little is known about Rodinia's configuration and geodynamic history. Paleomagnetic evidence provides some clues to the paleolatitude of individual pieces of the Earth's crust , but not to their longitude, which geologists have pieced together by comparing similar geologic features, often now widely dispersed.
