The oxygen fugacity of olivine-phyric martian basalts and the components within the mantle and crust of Mars

, 2003
The oxygen fugacity of olivine-phyric martian basalts is estimated using olivine-pyroxene- spinel equilibria, supported by detailed petrography. Results are plotted, along with previous oxygen fugacity estimates, against La/Yb, which is used as a proxy ...

THE STABILITY OF CARBONATE UNDER UPPER-MANTLE CONDITIONS AS A FUNCTION OF TEMPERATURE AND OXYGEN FUGACITY

, 1995
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.
