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 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.
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.
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 ...
A new study claims that the origin of bees is tens of millions of years older than previously believed.
The result was the formation of Gondwana. The Rodinia hypothesis assumes that rifting did not start everywhere simultaneously. Extensive lava flows and volcanic eruptions of Neoproterozoic age are found on most continents, evidence for large scale rifting about 750 Ma. [1]
The South Polar region of the Cretaceous comprised the continent of East Gondwana–modern day Australia, Zealandia, and Antarctica–a product of the break-up of Gondwana in the Cretaceous Period. The southern region, during this time, was much warmer than it is today, ranging from perhaps 4–8 °C (39–46 °F) in the latest Cretaceous ...
