Here we present a detailed study of a 139-m-long core of Francevillian rocks marked by carbonate δ 13 C (δ 13 C carb ) values of 5‰–9‰ that decline upsection to near 0‰, a trend inferred by many workers as a fingerprint of the LJE and its termination. However, we...

... previously recognised. However, the possibility of a post-LomagundiJatuli Excursion carbon isotope event cannot conclusively be ruled out. The directly overlying Denault Formation records a range in δ 13 C values, from −0.5‰ to +4.3‰, suggesting that it was deposited after the conclusion of the Lomagundi...

Although well-dated, contemporaneous carbonate successions with similar carbon isotope values are not documented, it is possible that some of these could have been miscorrelated with Lomagundi-aged carbonate successions in the absence of precise...

The last major Archaean event in the Zimbabwe Craton was the emplacement of the Great Dyke, a 550 km-long layered intrusion, at ca. 2575 Ma (Oberthu¨r et al. 2002). On the southern side of the craton is the Archaean Limpopo Belt, which...
