The potential significance of microbial Fe(III) reduction during deposition of Precambrian banded iron formations
During deposition of late Archean–early Palaeoproterozoic Precambrian banded iron formations (BIFs) the downward flux of ferric hydroxide (Fe(OH)_3) and phytoplankton biomass should have facilitatedExpand

Decoupling photochemical Fe(II) oxidation from shallow-water BIF deposition
Abstract Oxidized Fe minerals in Archean–Paleoproterozoic banded iron formations (BIFs) are commonly taken to indicate the presence of biogenic O 2 or photosynthetic Fe(II)-oxidizing bacteria in theExpand

Iron Formations: Their Origins and Implications for Ancient Seawater Chemistry
Iron formations are economically significant, iron- and silica-rich sedimentary rocks that are restricted to Precambrian successions. There are no known modern or Phanerozoic analogues for theseExpand

Petrography and geochemistry of the Dales Gorge banded iron formation: Paragenetic sequence, source and implications for palaeo-ocean chemistry
Abstract Banded iron formations (BIFs) have long been considered marine chemical precipitates or, as more recently proposed, the result of episodic density flows. In this study, we examined theExpand

Accumulation of Metals by Bacteriogenic Iron Oxides in a Subterranean Environment
Bacteriogenic iron oxides (BIOS) and groundwater samples were collected from 66 to 432 m underground at the Aspo Hard Rock Laboratory near Oskarshamn, Sweden. The twisted, iron oxide-encrusted stalksExpand
