Crystallization of diamond in the Mg-Si-C system has been studied at 7.5 GPa and 1800 °C with the Mg-Si compositions spanning the range from Mg-C to Si-C end-systems. It is found that as Si content of the system increases from 0 to 2 wt %, the degree of the graphite-to-diamond conversion increases from about 50 to 100% and remains at about this level up to 20 wt % Si. A further increase in Si

Experimental modeling of the formation of graphite and diamond as a result of carbide–fluid interactions was performed in the Fe 3 C–SiO 2 –Al 2 O 3 –(Mg,Ca)CO 3 systems at 6.3 and 7.5 GPa and 1100–1650 C. In the experiments with ƒO 2-gradient (7.5 GPa, 1250–1350 C), graphite + magnesiowüstite + garnet ± cohenite asselage was formed.
