Iron, Carbon, and Oxygen Isotope Compositions of Banded Iron Formation Carbonates Demonstrate a Major Role for Microbial Dissimilatory Iron Reduction in 2.5 b.y. old Marine Environments
Abstract
Fe, C, and O isotope data on carbonates of 2.5 Ga banded iron formations demonstrate formation via microbial dissimilatory iron reduction rather than precipitation from seawater, establishing the importance of this metabolism on the early Earth.
