>~Sequence of reconstructions from Li &al. shows how the breakup of Rodinia may have led to the assembly of Gondwana and Pannotia, (BIB: 2008PreR..160..179L):
(1) 900MYA\Rodinia,
(2) 760MYA\Rodinia breakup coincides with onset of widespread subduction in Mirovoi Ocean,
(3) 630MYA\Pannotia forms due to assembly of Gondwana & Laurentia, and
(4) 600MYA\after Pannotia’s amalgamation, onset of subduction along margins of Gondwana.
◊NOTE\ the S.A.N., the Saharan, Arabian, and Nubian portions that lay from the corner of Congo-SanFrancisco and West Africa. Such a reconstruction is not isolated to the aforementioned research group, but of persons representing other institutions. Another randomly selected group is, The Geological Society of London, & Yale personnel, who, with the use of the graphic below>, they had posed to put Pannotia: [as] A Supercontinent on Trial, and even with the questioning of her Super-potential, they also illustrate the aforementioned S.A.N.-craton/shields being very close together, hundreds of MYA.
