Simplified geological maps showing outlines of the Kalahari craton (A), pre–1.8 Ga Kalahari craton (B), and northeastern Kaapvaal craton (C) (adapted from de Kock et al., 2019; Hanson et al., 2011; Olsson et al., 2016). U-Pb baddeleyite age constraints are from the Mashonaland sill province (MSP; Söderlund et al., 2010; Hanson et al., 2011), post-Waterberg sill province (PWSP; Hanson et al., 2004); and Black Hills dike swarm (BHDS; Olsson et al., 2016; Wabo et al., 2019; this study). 40Ar-39Ar age is from Layer et al. (1998). Soutpansberg Basin U-Pb zircon ages are from Geng et al. (2014). Paleomagnetic data are from the MSP (McElhinny and Opdyke, 1964; Bates and Jones, 1996), Mazowe dike swarm (MDS; Wilson et al., 1987), PWSP (Hanson et al., 2004), BHDS (Layer et al., 1998; Lubnina et al., 2010; Letts et al., 2011; Maré and Fourie, 2012; Wabo et al., 2019; this study); and Soutpansberg Group and post-Soutpansberg sill province (PSSP; Hanson et al., 2004; Gose et al., 2006).

(A) Paleomagnetic site means from ca. 1.89 to <1.83 Ga units grouped and color coded according to magmatic province. The Post-Waterberg sill province (PWSP) mean differs significantly from the Mashonaland sill province (MSP) mean (the separation angle y0 = 25.4° >the critical angle yc = 11.0°) but is indistinguishable from the Black Hills dike swarm (BHDS) mean (y0 = 4.9° < yc = 14.1°) and Soutpansberg Basin (SB) mean (y0 = 4.6° < yc = 18.1°). PSSP—post-Soutpansberg sill province. α95 is the radius of 95% confidence around the mean. (B) Crystallization ages and definition of magmatic episodes. (C) Magnetic inclination of directly dated units with dike LDH highlighted. MSWD—mean squared weighted deviation. Vertical error bars represent 2σ uncertainty in Ma, and horizontal error bars represent 95% confidence bounds of the inclination. (D) Site means according to age. BHDS dikes with positive inclination are inferred to belong to the ca. 1.87 Ga episode. The ca. 1.87 Ga mean is indistinguishable from the ca. 1.86 Ga mean (y0 = 11.9° < yc = 20.3°) and ca. 1.85 Ga mean (y0 = 1.4° < yc = 15.9°). (E) Fennoscandia and Superior virtual geomagnetic pole (VGP) latitude (numbering as per Table S4 [see footnote 1]).

(a) Relief map of southern Africa, emphasizing the present-day drainage basin of the Limpopo river, which has seen very significant erosion since breakup of the Gondwana supercontinent. Note the erosional incision made by the Limpopo river. The position of the geological map in Figure 1b is indicated. (b) Simplified geological map of eastern South Africa and adjacent parts of Mozambique, Swaziland, Zimbabwe and Botswana, based on Schlüter (2006) with supplementary data from Förster (1975a), Botha and de Wit (1996) and Rutten et al. (2009). “Archaean” includes crystalline basement and Archaean supracrustal cover of the Kaapvaal Craton, southern rim of the Zimbabwe Craton and the Limpopo Belt. Sampling localities and major modern rivers are shown. Arrows indicate main late Mesozoic - early Cenozoic transport directions deduced from sedimentological data (from Förster, 1975a and Botha and de Wit, 1976).

Cumulative distribution curves for 207Pb/206Pb detrital zircon ages, filtered on a minimum value of the 206Pb/204Pb ratio of 2 000 (or on a corresponding upper limit for common 206Pb of 0.2%). (a) Magaliesberg Formation. Samples outside of the Bushveld aureole are from the present study and Andersen and Elburg (2022). Data on samples 618, 620, 733, 734, 735 and 739 have been pooled, sample 619 is shown separately. Data from samples taken within the contact aureole are from Zeh et al. (2016) and Andersen et al. (2019a). The minimum limit of deposition of the Pretoria Goup at 2 060 Ma is shown, and prominent age fractions are highlighted by shaded backgrounds. (b) Samples from the northern area, Timeball Hill (Thabazimbi) and Leeuwpoort (Rooiberg inlier) formations. Prominent age fractions in the Leeuwpoort Formation at 2 080 to 2 150 Ma and in the Timeball Hill Formation at 2 360 to 2 500 Ma and 2 750 to 3 000 Ma are highlighted by background shading. Note that the age tails younger than 2 080 Ma and 2 360 Ma, respectively, disappear if only formally concordant grains are considered. (c) Post-Magaliesberg formations in the central (Rayton Fm) and southeastern areas. Prominent age fractions at 2 080 to 2 150 Ma in the Steenkampsberg Fm and 2 200 to 2 350 Ma in the Lakenvalei Fm are highlighted by background shading. Note that samples of Lakenvalei Formation sandstone outside of the aureole (this work) and inside (Zeh et al., 2016) show the same age fractions, the differences between the two are only in their relative abundance. Both of the Palaeoproterozoic age fractions (2 080 to 2 150 Ma and 2 200 to 2 350 Ma) are present in samples of the Houtenbek Formation (Zeh et al., 2020). (d) Age distributions for comparison: Zircon from volcanic tuff layers in the Timeball Hill Formation and the Lephala Formation in the extension of the Transvaal basin into Botswana (also known as the ”Bushveld Basin”). Detrital zircon in the post-Bushveld Palaeoproterozoic Waterberg Group of the Waterberg and Nylstroom basins (Andersen et al., 2019b) and Wylliespoort formation in the Soutpansberg Basin (Andersen et al., 2020a) and the Okwa Group, Botswana, whose age of deposition is unconstrained (Andersen et al., 2020b). Distribution curves for the ”Quartzite II” of the Gumbu Group in the Limpopo Belt (Buick et al., 2003; Zeh and Kirchenbaur, 2022) are shown for comparison. This quartzite has detrital zircon distributions overlapping with the younger part of the distributions in the Waterberg, Okwa and Soutpansberg sandstones, but not with the Pretoria Group samples shown in (a) to (c).
