HIGHLIGHTS
- who: Jérémie Aubineau from the University of have published the paper: Microbially induced potassium enrichment in Paleoproterozoic shales and implications for reverse weathering on early Earth, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
- what: The authors highlight that K enrichments are localized in illite particles within fossilized MRS, and, most crucially, that this provides insight for the search of biosignatures in early Earth's sediments where stable isotope evidence are controversial. The authors discuss how these findings have important implications for Earth's climate and ocean chemistry in the Paleoproterozoic.
