Pyrites were measured in order to provide insights into their origin. Light and variable S isotope compositions in pyrite have been used to infer the influence of sulphate-reducing bacteria (and subsequent Se precipitation by sulphate-reducing microbes), whereas heavier S isotope compositions indicate a non-biological origin (i.e. physical and chemical diagenesis).

Liberated SO2 gases were analysed on a VG Isotech SIRA II mass spectrometer, with standard corrections applied to raw δ66SO2 values to produce True δ34S. Stable isotope geochemistry is concerned primarily with the relative partitioning of isotopes among substances (i.e. changes in the ratios of isotopes), rather than their absolute abundances. The principal ratio of concern in sulphides is 34S/32S, i.e. in the δ34S notation, with parts per thousand or per mille (‰) variations from the V-CDT standard. The standards employed were internationally certified reference materials NBS-123 and IAEA-S-3 (supplied by the IAEA) and Scottish Universities Environment Research Centre (SUERC) laboratory standard CP-1.
