Evidence for oxygen-conserving diamond formation in redox-buffered subducted oceanic crust sampled as eclogite

Billions of years ago, pieces of subducted oceanic crust were trapped as eclogites in the mantle keels beneath continents. Comparing eclogitic minerals protected inside and evolving outside of ancient diamonds reveals no change in redox state.
