recommendations! Published in 2017 at "Chemical Geology"

DOI: 10.1016/j.chemgeo.2016.12.006

Abstract: Abstract Multiple sulfur isotope variability in Archean sedimentary rocks provides constraints on the composition of the Earth’s earliest atmosphere. The magnitude and sign of mass-independent anomalies reflect not only atmospheric processes, but also transformations due… read more here.
