Multiple sulfur-isotope signatures in Archean sulfates and their implications for the chemistry and dynamics of the early atmosphere.
Paper summary
Uses spatially resolved sulfur-isotope measurements in ancient sulfate minerals to examine atmospheric chemistry and sulfur cycling. Different isotope populations and comparisons with modern aerosols complicate simple interpretations of ancient anomalies.
Relevance to the project
An evidence-quality example for distinguishing multiple processes producing similar signatures. Relevant to interpreting environmental change without automatically attributing it to organisms.
Historical reconstruction depends on proxy and preservation assumptions.
