There may be significant primitive water reservoirs thousands of kilometers deep within the Earth.

Journalists learned from the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences that recently, the research team at the institute has achieved a breakthrough by simulating the extreme environment at 660 kilometers underground through high-temperature and high-pressure experiments. They discovered that the major mineral in the mantle, bridgmanite, has significant water retention capabilities at high temperatures, suggesting the existence of previously undiscovered important primitive water reservoirs deep within the earth. This finding updates the understanding of water storage and distribution in the deep earth, indicating that deep-seated water may be a key force driving the transformation of Earth into a habitable planet. The related results were published on December 12 in the international academic journal "Science".
