Please feel free to contact me with any questions !The banded iron layers were formed in sea water as the result of oxygen being released by photosynthetic bluegreen algae (cyanobacteria). This oxygen then combined with dissolved iron in the Earth's oceans to form insoluble iron oxides, which settled to the bottom as a thin layer. These iron oxides alternated with the deposition of (anoxic mud) that formed shale and chert. Each band is similar to a glacial varve, to the extent that the banding is assumed to result from cyclic variations in available oxygen. Most BIFs are Proterozoic in age (although some are Late Archean), and do not form today - they're "extinct"! Many specific varieties of iron formation are known, and some are given special rock names. For example, jaspilite is an attractive reddish & silvery gray banded rock consisting of hematite, red chert ("jasper"), and specular hematite or magnetite
