Understanding what governs the speciation in the C–O–H–N system aids our knowledge of how volatiles affect mass transfer processes in the Earth’s interior. Experiments with aluminosilicate melt + C–O–H–N volatiles were, therefore, carried out with Raman and infrared spectroscopy to 800 °C and near 700 MPa in situ in hydrothermal diamond anvil cells. The measurements were conducted in situ with ...
H2O, CO2, SO2, O2, H2, H2S, HCl, chlorinated hydrocarbons, NO, and other trace gases were evolved during pyrolysis of two mudstone samples acquired by the Curiosity rover at Yellowknife Bay within Gale crater, Mars. H2O/OH-bearing phases included 2:1 phyllosilicate(s), bassanite, akaganeite, and amorphous materials. Thermal decomposition of carbonates and combustion of organic materials are can...
The chemical equilibria concerning formic acid are computationally investigated in water over a wide range of thermodynamic conditions. The solvation free energies for relevant C1 compounds are evaluated in the method of energy representation, and are used to assess the solvent effect on the formic acid reactions. In the two competitive decomposition processes of formic acid, the solvent strong...
Introduction: The early climates of Earth and Mars appear to have been relatively warm, despite the existence of a less luminous young Sun [1]. Most attempts at reconciling these apparently contradicting observations rely on atmospheres that are richer in greenhouse gases (GHGs) than the present atmospheres of either planet [2]. The major contribution to most plausible greenhouses is from CO2 a...
The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...
The thermal induced variations of water inclusions in their OH stretching mode region were probed in quartz veins from Dharwar Craton, India, using fourier transformed infrared spectroscopy (FTIR) in the temperature range 25 to 300 oC. All the inclusions have composition H2O-NaCl-CO2. The peak positions monotonously shift to higher wavenumbers with increasing temperature with slopes of 0.23 and...
