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 ...
Rifted off Rodinia at about 840 Ma. Then accreted to North Africa with large volume of juvenile crust during the Pan-African orogeny to form the Arabian-Nubian Shield. [4] [5] Arctica: 2565 Neoarchean Supercraton [6] Argoland: 155 an archipelago of microcontinents Rifted off Australia 155 Ma ago after splitting into microcontinents about 215Ma ...
The term Pan-African was coined by Kennedy 1964 for a tectono-thermal event at about 500 Ma when a series of mobile belts in Africa formed between much older African cratons. At the time, other terms were used for similar orogenic events on other continents, i.e. Brasiliano in South America; Adelaidean in Australia; and Beardmore in Antarctica.
The Pan-African Ocean is a hypothesized paleo-ocean whose closure created the supercontinent of Pannotia. [1] The ocean may have existed before the break-up of the supercontinent of Rodinia. The ocean closed before the beginning of the Phanerozoic Eon, when the Panthalassa ocean expanded, and was eventually replaced by it.
The East African Orogeny (EAO) is the main stage in the Neoproterozoic assembly of East and West Gondwana (Australia–India–Antarctica and Africa–South America) along the Mozambique Belt. [ 2 ] Gondwana assembly
In southwestern central Africa the granulite cooling ages range between 587 and 576 Ma, while in northeast Brazil they range from 568 to 500 Ma. [6] However, aeromagnetic and gravity data give evidence of continuity between the TBL lineament , the Sobral fault in northeastern Brazil, the Kandi fault zone in Benin and the Trans-Saharan Belt ...
Pannotia broke apart in the late Precambrian into Laurentia, Baltica, Siberia, Gondwana. A series of continental blocks, the Cadomian, Avalonian, Cathaysian, Cimmerian terranes, broke away from Gondwana and began to drift north.
Extent (orange regions) of the Grenville orogeny, after Tollo et al. (2004) and Darabi (2004) The Grenville orogeny was a long-lived Mesoproterozoic mountain-building event associated with the assembly of the supercontinent Rodinia.
