THE BIOTIC PROCESSES IN SULFIDEBEARING MINE TAILINGS IN WINTER ACCORDING TO GEOCHEMICAL AND GEOPHYSICAL DATA
A close relationship has been established between the concentration of dimethyl sulphide in the near-surface layer of the atmosphere, the soil temperature and the electrical resistivity as a result of studies of sulphide-bearing mine tailings in winter. A local anomaly of the reduced electrical resistivity which corresponds to a soil with a positive temperature is found. The concentration of dimethyl sulphide is increased in the near-surface layer above this area, which we associate with methylation of sulfide-bearing compounds by autorotrophic microorganisms.
