  • Geochemical evidence suggests the iron- and silica-rich precipitates that compose large Neoarchean and Paleoproterozoic iron formations formed along a chemocline between iron-rich deep water and iron-poor surface water. Sedimento-logical evidence indicates many large iron formations accumulated in marine shelf environments during major transgressions. We suggest this occurred because the chemocline could only impinge on continental shelves during times of sea-level rise or highstand. On the… CONTINUE READING
