Identify Metamorphic and Primary Multiple Sulfur Isotopic Signatures in the 2.7 Ga Pyrite Nodules from the Southwestern Superior Province (Minnesota, USA)
DownloadSpring 2016
Sulfur isotopes of some Archean rocks show unique mass independent fractionation (S-MIF) signatures, which are generally considered to have been produced by UV radiolysis on volcanic SO2 in the oxygen-free Archean atmosphere. Based on the distinct S-MIF signals of different sulfur sources (i.e.,...
