Biogeochemistry of Sulfur Isotopes

Reviews in Mineralogy and Geochemistry, 2001
Sulfur, 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

Sulfur Isotopic Composition of Mangroves

Isotopes in Environmental and Health Studies, 1998
Abstract 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.

Seawater Sulfur Isotope Fluctuations in the Cretaceous

Science, 2004
The 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.
