Thermochemical oxidation of methane induced by high-valence metal oxides in a sedimentary basin

The role of thermochemical oxidation of methane (TOM) by high-valence metal oxides as a potential methane sink remains poorly understood. Here, the authors present evidence of TOM induced by Mn(Fe) oxides in a sedimentary basin, which yields calcite with extremely negative δ13C values (−70 to −22.5‰...

Sumario:The role of thermochemical oxidation of methane (TOM) by high-valence metal oxides as a potential methane sink remains poorly understood. Here, the authors present evidence of TOM induced by Mn(Fe) oxides in a sedimentary basin, which yields calcite with extremely negative δ13C values (−70 to −22.5‰, VPDB).
