A new study suggests that Africa might be splitting apart along the Kafue Rift in Zambia, a long crack in the Earth's crust. Unlike typical plate boundary formation indicated by earthquakes and volcanoes, this discovery was made by analyzing hot spring water. Researchers detected deep mantle gases, specifically helium isotopes, escaping from springs within the rift zone, indicating a direct connection to the Earth's mantle. Led by Professor Mike Daly of the University of Oxford, a team sampled gas from eight geothermal wells and springs, finding a clear mantle component in six springs located within the Kafue Rift, a signature absent in springs outside the rift. This strong contrast ruled out contamination and confirmed the deep origin of the gases, suggesting that the rift is actively reaching down into hot rock. The helium isotope signatures from the Kafue Rift were comparable to those found in the East African Rift system, an older, well-established rift that has been opening for millions of years. This comparison suggests that the Kafue Rift is in an earlier stage of the same geological process, indicating a newly active plate boundary forming in central Zambia.
