Volcanic Influence on Atmospheric Sulfur Cycle in 2.7 Ga inferred from Multiple Sulfur Isotope Record of Pyrite Nodules in Black Shales from Nimbus, Western Australia
DownloadSpring 2018
Sulfur isotope compositions of Archean sulfide and sulfate minerals show mass-independent fractionation (S-MIF) signatures, which are characterized by non-zero Î33S and Î36S values. Producing the Archean S-MIF signal requires an O2-free atmosphere where broad-band UV radiation can penetrate to...
