Constraints on the sulfur subduction cycle in Central America from sulfur isotope compositions of volcanic gases
(European Association of Geochemistry, 2022-01-20)
The sulfur cycle at convergent margins remains poorly constrained yet is fundamentally important for understanding the redox state of Earth's reservoirs and the formation of ore deposits. In this study we investigate the ...
Sulfur and carbon isotopes in scapolite-bearing granulites of the São José do Rio Pardo area, Brazil
(1992-07-01)
Sulfur and carbon isotope compositions of ten scapolites from granulite-facies rocks of the São José do Rio Pardo area, Guaxupé Complex, Brazil, were measured. Scapolite is the primary and major rock-forming mineral in ...

Methionine to cystine ratio in the total sulfur amino acid requirements and sulfur amino acid metabolism using labelled amino acid approach for broilers
(2018-11-22)
Background: Assuming that part of Methionine (Met) is converted into Cystine (Cys), but ignoring the rates with which such phenomenon occurs may lead to an excessive supply of Met in poultry diets. Such inconvenient could ...
Isotope determination of sulfur by mass spectrometry in soil samplesDeterminação isotópica de enxofre por espectrometria de massas (irms) em amostras de solo
(Sociedade Brasileira de Ciência do Solo, 2012)
Sulphur plays an essential role in plants and is one of the main nutrients in several metabolic processes. It has four stable isotopes (32S, 33S, 34S, and 36S) with a natural abundance of 95.00, 0.76, 4.22, and 0.014 in ...
Geochemical and Isotopic Signature of Pyrite as a Proxy for Fluid Source and Evolution in the Candelaria-Punta del Cobre Iron Oxide Copper-Gold District, Chile
(Society of Economic Geologists (SEG), 2020)
Pyrite is ubiquitous in the world-class iron oxide copper-gold (IOCG) deposits of the Candelaria-Punta del Cobre district, documented from early to late stages of mineralization and observed in deep and shallow levels of ...
