| dc.description.abstract | A burning peat site in the Po Valley (Italy) has been investigated for the first time. Beyond the smoke from the smoldering combustion of peat, there are carbonatic concretions and huge amounts of methane in the soil (>60% by vol.), leading to fluxes to the atmosphere of the order of 10 to the power of 2/10 to the power of 3 mg m to the power of -2 d to the power of -1. A wide range of analyses (gas composition, stable isotopes of CH4 and CaCO3, methane radiocarbon) were performed in order to understand whether methane is produced by peat layers or seeps from deeper natural gas reservoirs. The quasi-fossil character of CH4, methane-derived carbonates, methane-stable isotopic compositions related to marine carbonates reduction, the presence of helium, and a fault corresponding to the burning site all converge to indicate that the major part of the methane ascends from deep horizons. Such methane seepage is likely to feed the peat combustion, explaining the observed phenomena and the large outbursts of historical gas-emission events. | en |
