Short summary
Banded iron formations (BIFs) are chemical sediments last seen in the marine sedimentary record ca. 600 million years ago. Here, we report on the formation mechanisms of a modern BIF analog in the Cape Vani sedimentary basin (CVSB) on Milos Island, Greece, demonstrating that rare environmental redox conditions, coupled to submarine hydrothermal activity and microbial processes, are required for these types of rocks to form in the modern marine biosphere.
