Intense biogeochemical iron cycling revealed in Neoarchean micropyrites from stromatolites
Paper summary
Measures iron-isotope compositions of micropyrites in ancient stromatolites. Spatially resolved geological evidence is used to investigate intense iron cycling and possible metabolic contributions while considering abiotic and alteration alternatives.
Relevance to the project
A reminder to distinguish biological organization from abiotic processes producing similar signatures. Supports multiple null models when interpreting aggregate morphology or resource flux.
Isotope signatures do not uniquely identify metabolism without contextual evidence.
