Geochemical Clues Hint Africa May Be Forming a New Tectonic Boundary
TL;DR
An international Frontiers in Earth Science study found elevated helium isotope ratios and mantle-like CO2 in samples from the Kafue Rift in Central Africa, suggesting mantle fluids are reaching the crust and potentially signaling the early stages of a new plate boundary that could eventually split sub‑Saharan Africa. The result is preliminary, but if confirmed it could open geothermal and other resource opportunities, with follow-up research planned across the Southwest African Rift System.
