Geochemistry of pyrite from diamictites of the Boolgeeda Iron Formation, Western Australia with implications for the GOE and Paleoproterozoic ice ages

TL;DR: In this paper, a compilation of S-isotope data from pyrite in the Boundary Ridge diamictites analyzed in this study and previous work ( Williford et al., 2011 ) defines multiple δ 34 S vs. δ 33 S arrays, consistent with an origin of detrital pyrites from the underlying Hamersley and Fortescue groups.
Journal ArticleDOI
Aspects of the Archean-Proterozoic transition: How the great Huronian Glacial Event was initiated by rift-related uplift and terminated at the rift-drift transition during break-up of Lauroscandia
TL;DR: Mazumder and Eriksson as mentioned in this paper showed that the early Archean-Proterozoic sedimentary record contains evidence of the world's first widespread glacial episodes, which have come to be known as the Huronian Glacial Event.
Journal ArticleDOI
Sulfur isotope characterization of primordial and recycled sources feeding the Samoan mantle plume
TL;DR: In this paper, the relationship between Δ 33 S and radiogenic tungsten, helium and lead isotopes from 7 Samoan basalts (from the islands of Ofu, Vailulu'u and Malumalu) was investigated.
Reconstructing Earth's Surface Oxidation Across The Archean- Proterozoic Transition

TL;DR: In this article, the earliest recorded positive carbon isotope anomaly was found in the Transvaal Supergroup of South Africa, in phase with sulfur isotopes, and the authors linked these environmental perturbations to the Great Oxidation Event (ca. 2.3 Ga).
Journal ArticleDOI
Quantification of sulphide oxidation rates in marine sediment
TL;DR: In this paper, the authors present an experimental method to directly determine sulphide oxidation rates in undiluted marine sediment incubations and find that sulphide oxidization rates in the top two centimetres of organic-rich coastal sediments were greater than rates of sulphide production through sulphate reduction.

Geochemistry of Hydrothermal Ore Deposits
TL;DR: In this paper, Skinner et al. discuss the relationship between hydrous alteration and its relationship to hydrous fluid composition in the formation of sulfide-sulfide ores.
Journal ArticleDOI
Sedimentary pyrite formation: An update
TL;DR: In this article, it was shown that organic matter appears to be the major control on pyrite formation in normal (non-euxinic) terrigenous marine sediments where dissolved sulfate and iron minerals are abundant.
Journal ArticleDOI
The age curves of sulfur and oxygen isotopes in marine sulfate and their mutual interpretation
TL;DR: In this article, a model involving symmetrical fluxes is introduced to take advantage of the oxygen data, and the measured δ34S and δ18O correspond to variations in these isotopes in sulfate of the world ocean surface.
