Carbonatites are familiar to students of petrology as rare igneous rocks formed
predominantly of carbonate, whose only modern expression is a single active volcano that …

Perhaps the first point to address in this chapter is what role, or roles, experimental petrology
can play in understanding the formation of natural diamond. As can be seen from the other …

Micro-inclusions in cloudy diamonds from Koffiefontein consist of three main types: silicates,
carbonates and brine inclusions. The silicates belong to either the eclogitic or the peridotitic …

We have experimentally studied the formation of diamonds in alkaline carbonate–carbon
and carbonate–fluid–carbon systems at 5.7–7.0 GPa and 1150–1700° C, using a split …

Phase relations in the K2CO3-MgCO3 system have been studied in high-pressure high-
temperature (HPHT) multi-anvil experiments using graphite capsules at 6.0±0.5 GPa …

Silicates, carbonates and brine were detected in microinclusions in cloudy diamonds from
Koffiefontein. The silicates belong to either the eclogitic or the peridotitic paragenesis. They …

Crystallization of diamond and graphite from the carbon component of magnesite, upon its
decarbonation in reactions with coesite and enstatite at pressures of 6-7 GPa and …

This study introduces a novel ICCU-RWGS process using Li, Na, and K carbonates mixed
with boric acid as dual functional materials, enhancing CO 2 capture and conversion without …

The capability of iron nitride, Fe3N for converting graphite to diamond was explored at P= 7
GPa and T= 1550–1850° C in experiments with a duration of 20 h. It was established that …

Diamond is impressive because of its wide range of extreme properties. By most measures,
diamond is 'the biggest and best': it is the hardest known material, has the lowest coefficient …
