A new study published in Frontiers in Earth Science has found helium and carbon isotope signatures in Zambian hot springs that indicate mantle-derived fluids are reaching the surface through the Kafue Rift, providing the first direct geochemical evidence of active continental rifting along the 2,500-kilometer Southwest African Rift System. The findings arrive alongside a separate Nature Communications study showing that the Turkana Rift in Kenya has thinned past the point of irreversible breakup, raising questions about how far south and how fast Africa's tectonic division extends — and what it means for the millions of people and billions of dollars in mineral wealth sitting atop the fault lines.
