3.1 billion-year-old rocks in Australia reveal a forgotten chapter of Earth’s water cycle
Researchers studying 3.1 billion-year-old rocks in Australia's Pilbara Craton have discovered evidence of an ancient water cycle. The findings suggest that surface water was being transported into the Earth's mantle through subduction much earlier than previously thought.
Why it matters
This discovery provides critical insights into the early evolution of Earth's geology and the long-term history of its water cycle.
