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 ...
Animation of the break-up of the supercontinent Pangaea and the subsequent drift of its constituents, from the Early Triassic to recent (250 Ma to 0).. This is a list of paleocontinents, significant landmasses that have been proposed to exist in the geological past.
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 ]
Eburnean Orogeny, series of tectonic, metamorphic and plutonic events establish Eglab Shield to the north of West African Craton and Man Shield to its south – Birimian domain of West Africa established and structured. c. 2,200 Ma – Iron content of ancient fossil soils shows an oxygen built up to 5–18% of current levels.

A decade later this continental collision was named the East African Orogeny, but it was also realised that this was not the simple bringing together of two halves. Rather, it was the piecemeal assembly of several much smaller cratonic elements that once formed an earlier supercontinent (today known as Rodinia ), a process that eventually ...
Within the West African Craton, there is a large amount of mining activity covering resources such as gold, copper, cobalt, silver, tin, and zinc. [ 24 ] Artisanal mining activity in the craton dates back to the early 1960s which used quartz vein debris as a gold indicator. [ 25 ]
The hypothetical supercontinent is sometimes referred to as Pannotia or Vendia. [137]: 321–322 The evidence for it is a phase of continental collision known as the Pan-African orogeny, which joined the continental masses of current-day Africa
There were many kingdoms and empires in all regions of the continent of Africa throughout history. A kingdom is a state with a king or queen as its head. [1] An empire is a political unit made up of several territories, military outposts, and peoples, "usually created by conquest, and divided between a dominant centre and subordinate peripheries".
