| Abstract: | Fugacities of H2, N2, O2, CH4, H2O, H2S, NH3, CO, and CO2 are calculated on the basis of the extrapolation of the caloric properties, and those of the compressibility of substances into the region of pressures up to 2 Mbar and of temperatures up to 4000K. Several equilibrium mineralogical reactions are calculated. The most probable sequence of decreasing the magnitudes of the equilibrium molar fractions (masses) of these gases in the lower mantle of the earth is predicted. |
