- W1512804539 abstract "Sulfur isotopes display mass independent fractionation (MIF) according to pyrite morphology in some late Archean Hamersley Basin sediments [1]. These data provide valuable insight into the distribution of late Archean microbial habitats when analysed in the context of depositional environment and the carbon isotope systematics of the host rock,. In the shallow water sediments of the ~2.6 Ga Wittenoom and Carawine Formations, variably negative organic carbon isotopic compositions occur without a corresponding carbonate carbon isotope depletion, while multiple pyrite morphologies exhibit little variation in sulfur MIF values in individual samples. This pyrite displays two distinct sulfur isotope distribution patterns. One is indicative of microbial sulfate reduction in a somewhat oxidised environment, with low negative Δ33S corresponding to a diverse range of positive and negative δ34S values. The other may represent an atmospheric mixing array with positive Δ33S values corresponding to generally positive δ34S [2]. Regardless of morphology, the pyrite in each sample contains sulfur from a common source. In the relatively deeper water sediments of the ~2.7 Ga Jeerinah Formation, morphology dependent pyrite sulfur MIF occurs together with depleted carbonate carbon isotope compositions and the strongly depleted organic carbon isotope values that are common in the organic rich sediments of the Hamersley Basin. The samples exhibit positive sulfur MIF values and can be separated into two populations. One comprises an atmospheric mixing array similar to that of the overlying shallow water sediments, the other may be the result of multi-stage sulfur cycling, involving both oxidising and reducing processes and/or metabolisms. This trend is characterised by positive Δ33S and a range of δ34S values. Biological multi-stage carbon cycling, possibly involving methanogenesis, methanotrophy and anaerobic methane oxidation, may have lead to the strongly depleted organic and carbonate carbon isotopes, which occur in the same anaerobic deeper water sediments that contain evidence of multi-stage sulfur cycling and multiple sulfur sources." @default.
