First Signs of a Future Tectonic Split Are Bubbling Up in Zambia

Scientists found mantle-derived helium in hot springs in Zambia’s Kafue Rift, pointing to active tectonic rifting.

The isotope signal suggests magma or deep mantle fluids are rising beneath the region, not just shallow crustal processes.

This is new geochemical evidence that central Africa may be starting to split apart, potentially forming a future plate boundary.
