Abstract
The majority of the sulphur in these coals occurs in the organic form. All studied sulphur phases are relatively rich in 34S isotopes (δ34Sorganic = + 12.74â°, δ34Spyrite = + 10.06â°, on average). This indicates that marine bacterial sulphate reduction played a minor role in their formation, in the sense that isotopic fractionation was limited. It seems that the interstitial spaces of the peat closed rapidly during early diagenesis due to a regime of high depositional rate, leading to a relative enrichment of the heavy sulphur isotopes.
