Sulfur isotope fractionation between aqueous and carbonate-associated sulfate in abiotic calcite and aragonite [PDF]

, 2020
Sulfate (SO₄²⁻) incorporated into calcium carbonate minerals enables measurements of sulfur (S) isotope ratios in carbonate rocks. This Carbonate Associated Sulfate (CAS) in marine carbonate minerals is thought to faithfully represent the S isotope ...

Sulfur reduction distillation of sulfides and verification of the effect of sulfur isotopic fractionation during pretreatment

Journal of Analytical Science and Technology, 2023
Toxic gases can be emitted when sulfides form compounds with heavy metals; thus, a series of pretreatments are required prior to the analysis of sulfur isotope ratios to remove unnecessary elements.

Organosulfur Aerosols Likely Carried Sulfur MIF Signatures in the Early Earth’s Atmosphere

Geochemistry, Geophysics, Geosystems, 2023
Signatures of mass‐independent fractionation (MIF) of sulfur in Archean sulfide and sulfate minerals are widely thought to record an anoxic early Earth’s atmosphere.

Sulfur isotope fractionation during oxidation of sulfur dioxide: gas-phase oxidation by OH radicals and aqueous oxidation by H₂O₂, O₃ and iron catalysis [PDF]

Atmospheric Chemistry and Physics, 2012
The oxidation of SO2 to sulfate is a key reaction in determining the role of sulfate in the environment through its effect on aerosol size distribution and composition.

Digging Deeper: Bioturbation increases the preserved sulfur isotope fractionation

Frontiers in Marine Science, 2023
Bioturbation enhances mixing between the seafloor and overlying ocean due to changes the redox state of the sediment and influences the biogeochemical cycling of redox-sensitive elements such as sulfur. Before the widespread appearance of burrowing fauna

Multiple-sulfur isotope effects during photolysis of carbonyl sulfide [PDF]

Atmospheric Chemistry and Physics, 2011
Laboratory experiments were carried out to determine sulfur isotope effects during ultraviolet photolysis of carbonyl sulfide (OCS) to carbon monoxide (CO) and elemental sulfur (S⁰).
