Hidden inside two super-deep diamonds, rare mineral clues suggest cold slabs can drag phosphorus 700 kilometres down and help keep life’s ingredients in motion
Diamonds, once symbols of perfection, now reveal Earth's deep secrets. A recent study analysed a Brazilian diamond, finding mineral inclusions that show phosphorus, vital for life, can travel deep into the mantle. However, this journey is rare and requires specific cold conditions, suggesting most of Earth's phosphorus remains near the surface, supporting life's evolution.
