Formation of natural diamond: An experimental perspective

Experimental synthesis of nucleosides under conditions modelling the Earth’s reduced initial atmosphere

“…In a type (4) study, we have demonstrated that a Fe 70 S 28 O 2 melt can reduce magnesite in the presence of orthopyroxene at 1300°C at 6 and 7.5 GPa, although graphite forms rather than diamond (Gunn and Luth, 2006).
