THE STABILITY OF CARBONATE UNDER UPPER-MANTLE CONDITIONS AS A FUNCTION OF TEMPERATURE AND OXYGEN FUGACITY
The stability of carbonate in the upper-mantle is a function of oxygen fugacity. Carbon-carbonate buffers such as EMOG (enstatite-magnesite-olivine-graphite) provide a lower fO2 limit for carbonate stability. For mantle compositions, the position of the carbonate-oxide equilibrium has been experimen...
