Magnetite biomineralization in ferruginous waters and

Nov 01, 2020 4.1. Magnetite formation, FeIII reduction, and Fe recycling. Magnetite formation in LM and LT is biologically induced, as it is associated with microbial reduction of the biologically reactive FeIII in the water column and uppermost sediments. Magnetite formation thus represents an important sink for microbially produced FeII.
