Deciphering sulfur cycling with multiple sulfur isotopes
Nature Reviews Earth & Environment, 2022Laetitia Guibourdenche explains the use of multiple sulfur isotopes in understanding past and present sulfur cycling.

Sulfur Isotopic Composition of Mangroves
Isotopes in Environmental and Health Studies, 1998Abstract Sulfur isotope ratios of mangrove leaves of 19 species were compared to discuss the species-specific characteristics of sulfur uptake and assimilation. The members of Rhizophora and Bruguiera always show remarkable enrichments of the light isotope, giving negative δ(34)S values in most cases.

Biogeochemistry of Sulfur Isotopes
Reviews in Mineralogy and Geochemistry, 2001Sulfur, with an atomic weight of 32.06, has four stable isotopes. By far the most abundant is 32S, representing around 95% of the total sulfur on Earth. The next most abundant isotope is 34S, followed by 33S, and finally 36S is the least abundant contributing only 0.0136% to the total (Table 1⇓). The natural abundances of sulfur isotopes, however, vary

Seawater Sulfur Isotope Fluctuations in the Cretaceous
Science, 2004The exogenic sulfur cycle is tightly coupled with the carbon and oxygen cycles, and therefore a central component of Earth's biogeochemistry. Here we present a high-resolution record of the sulfur isotopic composition of seawater sulfate for the Cretaceous.

Sources and Isotopic Composition of Atmospheric Sulfur
Science, 1961In nonindustrial areas the prime source of SO--4in rain and snow is atmospherically oxidized H2S that is produced predominately along coastal belts by anaerobic bacteria. The δ S34analyses of atmospheric SO--4vary from +3.2 to +15.6 per mil in contrast to +20.7 per mil for sea water SO--4.

The isotopic composition of plant sulfur
Organic Geochemistry, 1980Abstract The isotopic composition of sulfur has been studied in plants representative of various regions of the U.S.S.R., two oceanic islands, and atmospheric precipitations on land and in marine areas. In soils, the isotopic composition of sulfur in the atmospheric water varies as a result of sulfate reduction (increase of δ 34 S of the soil sulfate)

Sulfur Isotope Fractionation in the Biogeochemical Sulfur Cycle of Marine Sediments
Isotopes in Environmental and Health Studies, 2001Abstract The sulfur isotopic record of sedimentary sulfides (mainly pyrite) and sulfates shows considerable variations in time and plays an important role in the biological and geochemical interpretation, e.g., of the evolution of life and the oxygen partial pressure of Earth's atmosphere (e.g. [1]).

Sulfur isotopes and ore deposits
Economic Geology, 1960A geochemical history of the sulfur isotopes in the crust of the earth is presented. New measurements of the S³²/S³⁴ ratio on sulfide minerals are used to show that transport and depositional processes do not appear to produce appreciable variation in the relative abundance of the sulfur isotopes.

Centrifugal enrichment of sulfur isotopes
Journal of Radioanalytical and Nuclear Chemistry, 2013This work contains the results of the research for the complete cycle of the centrifuge enrichment process of all sulfur isotopes. As a result of this work there was obtained, and made available (by centrifuge enrichment process), for the first time hundreds of grams of all the isotopes of sulfur to high enrichment.
