THE explanation of why partial fusion of mantle peridotite sometimes yields basalts, sometimes kimberlites and sometimes carbonatites is given by the phase relationships in the system CaO–MgO–SiO2–CO2. The key is the intersection of a sub-solidus carbonation reaction with the solidus, which introduces carbonates as primary minerals alongside silicates on the surface of the liquidus. 
Links between Carbonatite and Kimberlite Melts in Chloride–Carbonate–Silicate Systems: Experiments and Application to Natural Assemblages
Recent data suggest an active role for chloride-bearing alkali carbonatitic melts in the formation and evolution of kimberlites, whereas experiments indicate that chlorides could be responsible for
Orthopyroxene survival in deep carbonatite melts: implications for kimberlites
Kimberlites are rare diamond-bearing volcanic rocks that originate as melts in the Earth’s mantle. The original composition of kimberlitic melt is poorly constrained because of mantle and crustal
Peridotite–CO2–H2O, and carbonatitic liquids in the upper asthenosphere
THE recent discovery that CO2 at upper mantle pressures has a dramatic effect on the melting temperature of peridotite (because the silicate assemblage becomes carbonated), and on the composition of
Mantle carbonatite eruptions: Crustal context and implications
Abstract High level carbonatites in south-east Zambia have sub-volcanic intrusion sequences similar to those of the classic Chilwa complex, with the significant addition of magnesiocarbonatite

Over recent decades, many experimental studies have focused on the effect of CO2 on phase equilibria and melting behaviour of synthetic eclogites and peridotites as a function of pressure and
Effect of variable carbonate concentration on the solidus of mantle peridotite
Abstract To explore the effect of variable CO2 concentrations on the solidus of natural carbonated peridotite, we determined near-solidus phase relations of three different nominally anhydrous,
Melting in the mantle in the presence of carbon: Review of experiments and discussion on the origin of carbonatites
Carbon emission at volcanic centers requires a constant balance between output (mostly by volcanism, either at plate boundaries or intraplate) and input (mostly at trench settings) of carbon from and
Petrogenetic grid for siliceous dolomites extended to mantle peridotite compositions and to conditions for magma generation
Decarbonation reactions in the system CaO-MgO-SiO_2-CO_2 involve calcite, dolomite, magnesite, and quartz, and the products enstatite, forsterite, diopside, and wollastonite, among others. Each
Solubility of CO2 in olivine melilitite at high pressures and role of CO2 in the earth's upper mantle
AbstractThe positions of the liquidi and the near-liquidus phases of olivine-melilitite+CO2 have been determined under MH-buffered and ‘furnace-buffered’ conditions up to 40 kb. It is found that CO2
The Transition from Carbonate to Silicate Melts in the CaO—MgO—SiO2—CO2 System
The compositions of melts in equilibrium with a lherzolite mineral INTRODUCTION assemblage were determined in the analogue system CaO– The common association of carbonatites with silicaMgO–SiO2–CO2
