The formation of Pannotia began during the [[Pan-African orogeny]] when the [[Congo Craton]] was logdedlodged between the northern and southern halves of the previous supercontinent [[Rodinia]] some 750 Ma. The peak in this mountain building event was around 640–610 Ma, but these continental collisions may have continued into the early Cambrian some 530 Ma. The formation of Pannotia was the result of Rodinia turning itself inside out.<ref name="Scotese-2009-Pannotia">{{Harvnb|Scotese|2009|loc=Reconstruction of Pannotia, pp. 71–72}}</ref>
 
When Pannotia had formed, Africa was located at the centre surrounded by the rest of Gondwana: South America, Arabia, Madagascar, India, Antarctica, and Australia. Laurentia, which 'escaped' out of Rodinia, [[Baltica]], and [[Siberia (continent)|Siberia]] kept the relative positions they had in Rodinia. The [[Cathaysia|Cathaysian]] and [[Cimmeria (continent)|Cimmerian terranes]] (continental blocks of southern Asia) were located along the northern margins of east Gondwana. The [[Avalonia]]n-[[Cadomian Orogeny|Cadomian]] terranes (later to become central Europe, Britain, the North American east coast, and Yucatán) were located along the active northern margins of western Gondwana. This [[orogeny]] probably extended north into the [[Ural Mountains|Uralian]] margin of Baltica.<ref name="Scotese-2009-Pannotia" />
