genesis of magnetite and hematite ores in BIF

Hydrothermal fluids responsible for the upgrading of magnetite and hematite in BIF are puzzling...what is so special about the fluids that dissolve the primary quartz bands? This talk presents key relationships that explain the nature of these fluids (data include whole rock geochemical data, mineral chemistry, fluid inclusion, and isotope data).
