...), Kaapvaal Craton, southern Africa, are two of the best exposed granite-greenstone belts. Their striking geological similarities has led to the postulated existence of Vaalbara, a Neoarchaean-Palaeoproterozoic supercraton. Although their respective TTG domes have been compared in terms of a common...

Possible Neoarchean–Paleoproterozoic supercraton reconstructions. (A) Pangea reconstruction at 200 Ma, in present South American coordinates, showing Archean cratons (gray, or colored and labeled) embedded within younger terranes (polygon outlines in gray, defined by Pehrsson et al., 2012; modern continental outlines in black).. (B) Proposed Superia supercraton (Ernst and Bleeker, 2010), based primarily on geometries of radiating dike swarms, with foci marked by stars. (C) Proposed Sclavia supercraton (French and Heaman, 2010) with its radiating dike foci. (D) Proposed Vaalbara supercraton (de Kock et al., 2009) based on stratigraphic comparison and paleomagnetic constraints. (E) More speculative Zimgarn juxtaposition (Smirnov et al., 2013) based on a limited number of dike ages, geometries, and paleomagnetic data. In (B)-(E), arrows show the present north orientation of each craton.

Bleeker (2003) discusses a Late Archaean geodynamic scenario wherein he evaluates three possible end-member models: (1) a single supercontinent (viz. the “Kenorland solution” based on the work of Williams et al. 1991 ) scenario; (2) a limited set of supercratons (e.g., Vaalbara, Superia...

Extant data have, however, been used to suggest a Vaalbara super-craton between 2.8 and 2.2 Ga, that break-up of Superia did not occur until 2.1 Ga, that break-up of Sclavia occurred at 2.0 Ga, and that these two supercratons were not likely adjacent from 2.4 to 2.2 Ga ( Salminen et al. 2021...

(B) Cumulative increase in the number of lithium minerals occurring in the lithium–cesium–tantalum (LCT) family of pegmatites and in all parageneses as a function of geologic time and the assembly of the supercontinents of Kenorland, Nuna, Rodinia, Gondwana, and Pangea, as well as the supercratons Vaalbara, Superia and Sclavia, based on the oldest reported occurrences in the geological record of 121 lithium minerals. Modified fromGrew et al. (2019). (C) Histogram showing estimates of the number of lithium minerals that had formed in a given 50 My interval in LCT pegmatites and in all parageneses based on the reported earliest, intermediate, and latest occurrences in the geologic record of 121 lithium minerals. The full names of the localities (number of lithium minerals in parentheses) are as follows: Tanco Mine, Manitoba (Canada); Tip Top Mine, South Dakota (USA); Kalahari manganese field, Northern Cape Province (South Africa); Lovozero and Khibiny alkaline complexes, Kola Peninsula (Russia); alkalic pegmatites from the Darai-Pioz Glacier, Alai Range (Tajikistan); Eastern Pedriza Massif, metasomatic rocks associated with the La Pedriza Pluton (Spain); Mont Saint-Hilaire alkalic complex, Monteregian Hills, Quebec (Canada).

Isotope evolution diagrams. (A) Initial εNd evolution diagram for depleted mantle isotopic array complementary to crustal array. Previous terrestrial data correspond to reference numbers given in Table S4. Two small green circles represent measured Lower and Upper Lava ages (Western Iron Ore Group, W-IOG) and initial εNd values reported in this study. Orange boxes represent supercontinent and/or hypothesized supercraton events found in literature (e.g., Mahapatro et al., 2012). P—Pangaea; G—Gondwana; R—Rodinia; N—Nuna; K—Kenorland; V—Vaalbara. Bars represent the range of initial εNd values for a suite of cogenetic samples. Light green band represents the depleted mantle (DM) evolution trajectory inferred from W-IOG data. The 3.42 Ga Lower Lava initial εNd value of +5.7, having been derived from a depleted mantle reservoir that formed soon after planetary differentiation, projects to a modern day εNd value of +23. Green circles—meta-basalts; yellow—ultramafics; brown—gabbro and amphibolite; light orange—anorthosite; grey—granitoids; white—sedimentary. (B) Plot of initial εHf versus absolute U-Pb age of zircons from the Singhbhum craton (see Chaudhuri et al., 2018; Sreenivas et al., 2019; Miller et al., 2018; Ranjan et al., 2020; Jodder et al., 2021; Dey et al., 2017). Three light-yellow bars represent Sm-Nd isotope age range for Lower Lava. The middle bar represents the isochron-derived age of 3420 Ma, while the other two bars represent the two end members of the ±140 m.y. age error. Zircons from the tuff unit give a U-Pb age of 3.39 Ga, represented as bold dashed vertical line. Given that this tuff unit lies above Lower Lava (Fig. S2), 3.39 Ga is its minimum age. Note that influence of depleted mantle occurs at ca. 3.5 Ga, coinciding with formation of W-IOG Lower Lava greenstones. Shaded gray regions in histogram represent major tonalite-trondhjemite-granodiorite (TTG) crustal formation events in Singhbhum. MORB—mid-ocean-ridge basalt; CHUR—chondritic uniform reservoir.

.... Rapid crust growth in the latest Archean suggests the existence of supercontinents, which still has no reliable proofs ( Condie, 2011 ). The known three dozens of Archean cratons appear to be fragments of large landmasses, judging by their similarity, and might have belonged to supercratons ( Bleeker...
