Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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.

Diversity of Sulfur Isotope Fractionations by Sulfate-Reducing Prokaryotes [PDF]
Applied and Environmental Microbiology, 2001 ABSTRACT Batch culture experiments were performed with 32 different sulfate-reducing prokaryotes to explore the diversity in sulfur isotope fractionation during dissimilatory sulfate reduction by pure cultures. The selected strains reflect the phylogenetic and physiologic diversity of presently known sulfate reducers and cover a ...

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.

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

Sulfur isotope rations of sulfide minerals from the deposit of the Tsuchikura mine, Shiga Prafecture, Japan [PDF]
, 1998 Sulfur isotope rations of sulfide minerals in the ore specimens from the deposit of the Tsuchikura mine are distrib-uted in a range from -0.8 to 5.4%, mostly from +0.5 to 3.0%, close to the previous data (from +1 to +3%) by Miyake and Sasaki (1980).

Fraction of Sulfur Isotopes during Reduction [PDF]
Bulletin of the Chemical Society of Japan, 1958 Barium sufaa labelled with sulfur-35 was reduced, and hydrogen sulfide evolved from the reactions was entrained with carben dioxide. The gas was led into two absorbing cells in series, the first of which contrined a known amount of aqueous zinc acetaa, for radioactivity measurement, and the second contained cadmium carbonate for sufide deaction.
