Primary hematite in Neoarchean to Paleoproterozoic oceans
Geological Society of America Bulletin, 2015Banded iron formations (BIFs) are ironand silica-rich chemical sedimentary rocks formed throughout the Archean and Paleoproterozoic Eras. The presence of hematite (Fe2O3) and magnetite (Fe3O4) in BIFs has led to the widespread assumption that Fe(II) oxidation must have occurred in the ancient oceans via either a biological or chemical mechanism ...

GROWTH AND MODIFICATION OF NEOARCHEAN-PALEOPROTEROZOIC CRUST
The temporal distribution of Earth’s crustal rocks exhibits distinctive age peaks, representing periods of significant crustal growth. Among these, the Neoarchean (2.7-2.5 Ga) and Paleoproterozoic (2.0-1.8 Ga) stand out as major periods of crustal formation in Earth’s early history.openaire +1 more source
