Even though a given mineral, for instance olivine, may contain only traces of dissolved H2O, CO2 and N2 the gases which evolve from its surface during heating comprise (a) highly reduced molecules such as H2, CH4, CmHn and more complex hydrocarbons, HCN and other N-bearing compounds (b) oxidized species in various degrees of oxidation from formaldehyde and CO to oxygen. These gases evolve sequentially besides H2O, CO2 and possibly N2, their relative amounts being controlled by experimental parameters such as the rate of heating. Preliminary indications of amino acids have been obtained by liquid extraction. The chemical complexity is a consequence of radical reactions between different solute species in the surface and the bulk of the mineral grains. Data for synthetic MgO and for mantle-derived olivine are presented.
