New research from Chinese scientists reveals how Earth's deep mantle stored vast amounts of water in its early years, a key to the planet's habitability.
The study, published in Science, shows that bridgmanite, the main mineral in the lower mantle, can trap significant amounts of water, especially at high temperatures.
Scientists recreated the extreme conditions of the lower mantle, finding that hotter temperatures increase bridgmanite's water storage capacity. This could have locked away water equivalent to 0.08-1 times the volume of today's oceans.
This water has gradually returned to the surface through volcanic activity, contributing to Earth's oceans and making our planet habitable. Discover more about this fascinating discovery!
