Ancient African bedrock holds clues to Earth's deep water cycles

Researchers probed the composition of 2-billion-year-old rock beneath southern Africa to understand how much water the planet's deepest layers contain. The findings could reshape models of mantle dynamics, volcanic activity, and ore deposits—with implications for mining, geothermal energy, and fundamental Earth science.
