Figure 2From: Multiple sulfur isotopes fractionations associated with abiotic sulfur transformations in Yellowstone National Park geothermal springsSulfur isotope composition in hydrothermal pools as a function of chloride to sulfate ratio. Detailed legend: Values of δ34S for sulfide (open circles) and sulfate (closed circles) in the water column of hydrothermal pools as a function of chloride to sulfate ratio. Solid line depicts δ34S of sulfate calculated with the use of the model proposed by Truesdell et al. [10] under assumption that δ34S of sulfide is zero.Back to article page
