“…Thickening of the cratonic lithosphere resulting from magmatism and deformation led to stabilization and the long‐term survival of the cratons, and is associated with overall depletion of lithospheric mantle (Griffin et al., 2009; Jordan, 1978, 1988; Pearson et al., 2021; Priestley et al., 2020). Following the termination of magmatism, the stabilized cratons were exhumed and eroded to variable extent, and then subsided to be unconformably overlain by laterally extensive basinal successions; for example, the Singhbhum Cover Sequence that accumulated across much of the Singhbhum Craton, the Fortescue Supergroup along the southern and eastern margins of the Pilbara Craton, the Pongola, Witwatersrand and Transvaal successions preserved in the central and eastern parts of the Kaapvaal Craton, and the Huronian Supergroup on the southern margin of the Superior Craton (Bennett et al., 1991; Catuneanu & Eriksson, 1999; Chowdhury, Mulder, et al., 2021; Frimmel, 2019; Hickman, 2012; Luskin et al., 2019; P. G. Eriksson et al., 2011; Thorne & Trendall, 2001). Empirical estimates of continental crustal thickness in the period 3.2–2.5 Ga suggest a slight decrease overall, either from ∼55 to ∼50 km (Tang et al., 2021) or from ∼40 to ∼35 km (Balica et al., 2020).…”

“…This is assumed to be reasonable since the two areas are close and tectonically similar. The geology of South Africa and Zimbabwe are similar, they both consist of Archean cratons which are almost of similar age and the cratons are both surrounded by mobile belts (Eriksson et al, 2011;Fouch et al, 2004;Jelsma and Dirks, 2002) During the 1963 -1991 period, the m blg magnitude scale was developed by Henderson (1974) and used for magnitude estimation in the southern African region by the Goetz Observatory. The Henderson (1974) relation (equation 2)…”

“…The Wilson Cycle can be seen as an integral part of the larger concept of the supercontinent cycle. When supercontinental dynamics are traced back into the deep geological past, as for the Proterozoic or even possibly the Archaean, it is clear that the relatively simple scenario of rifting of a large continental mass, separation of the relatively large daughter fragments on either side of a growing ocean, and eventual ocean closure together with reassembly of the earlier rifted margins in approximately similar mutual relationship (as implicit in Wilson's 1966 cycle derived from the Atlantic ocean example), becomes much more complex (e.g., Bleeker 2003;Eriksson et al 2011aEriksson et al , 2011b. Proterozoic supercontinents fragmented into many daughter components, and reassembly of the subsequent supercontinent several hundred million years later, encompassed a reassembly of fragments in a plethora of new relative orientations, reflecting multiple rotations and complex plate movements within a veritably Byzantine amalgamation history (e.g., Hartnady 1986;Hoffman 1991;Dalziel 1991;Moores 1991).…”
