United KingdomScientists have discovered two super-deep diamonds that provide new insights into how phosphorus cycles through the Earth's mantle. These diamonds, formed 700 kilometers beneath the surface, contain rare minerals like tuite, which suggests that phosphorus can reach the lower mantle under specific conditions. Researchers from the University of Alberta and the Carnegie Institution for Science found that phosphorus typically remains near the surface due to the extreme heat of subducting oceanic plates, preventing it from being locked away in the deeper mantle. This finding challenges previous assumptions about the long-term availability of phosphorus, a critical element for life, and highlights the importance of cool subduction zones in facilitating deep mantle cycling.
