Isotopes of sulfide and sulfate sulfur in nitrogen hot springs of the Bauntov group (Baikal Rift Zone).

The article presents a study on the sulfates and sulfide in nitrogen hot springs of the Bauntov group of the Baikal Rift Zone (BRZ) in the Vitim River Basin in Russia. It says that physicochemical characteristics of nitrogen hot springs were examined using analytical techniques and precipitates for the assessment of isotopes were obtained by deposition with cadmium acetate, sulfate sulfur, and barium chloride. The results suggest that sulfide sulfur in the hot springs is depleted in heavy isotopes compared with that of sulfates and the chemical oxidation of sulfide sulfur under reduced environments at high Eh values is inconceivable. It adds that the influence of sulfate reduction in the improvement of sulfate sulfur in a heavy isotope is apparent.
