\r\n\r\n\r\n\r\n\r\n\r\nBackground:<\/strong>\r\n\r\n\r\n\r\n\r\n\r\nBanded iron formations (BIF) are the world\u2019s largest and most widespread source of iron. The Carajas BIF of Brazil is associated with the presence of a high-grade iron ore and extensive cave development. The formation of these caves appears to be through microbial iron reduction and silica mobilization. The role and importance of silica in the formation of these caves is still unknown, so that is what we are trying to uncover.\r\n\r\n\r\n\r\n\r\n

We use bacterial cultures grown in both anaerobic and aerobic conditions with iron and silica. We then analyze these cultures with geochemical and biological analyses.\r\n\r\n\r\n\r\n\r\n
