Biogenicity of an Early Quaternary iron formation, Milos Island, Greece

A ~2.0‐million‐year‐old shallow‐submarine sedimentary deposit on Milos Island, Greece, harbours an unmetamorphosed fossiliferous iron formation ( IF ) comparable to Precambrian banded iron formations ( BIF s). This Milos IF holds the potential to provide clues to the origin of Precambrian BIF s, relative to biotic and abiotic processes. Here, we combine field stratigraphic observations, stable isotopes of C, S and Si, rock petrography and...
