This paper, published in the journal Geodynamics, summarizes evidence for superplume events in the Kaapvaal (South Africa) and Pilbara (Australia) regions. Flood basalts and graben-related sedimentary-volcanic deposits are interpreted as evidence for a global superplume event at 2.7 Ga. A possible second superplume event at 2.5 Ga may have been responsible for transgressive successions in both of these regions, but the evidence is less clear than the 2.7 Ga event.
