model: 241: Superior Fe (BC name is Lake Superior & Rapitan types iron-formation)
alteration: Some magnetite formed by replacement of ferrous iron minerals during diagenesis and most iron silicate probably formed by metamorphism of an early silicate mineral.
conc_proc: Soft ore formed during the mid to late Proterozoic and/or possibly as young as the Cretaceous by (1) interaction of supergene groundwater which caused oxidation of ferrous iron minerals (siderite), (2) leaching of chert and its replacement by secondary hematite and goethite, and (3) removal of large amounts of CO2. hard ore formed by oxidation of carbonate of iron formation to soft ore during a period of mid-Proterozoic weathering and metamorphism during the Penokean orogeny which caused the soft ore to recrystallize to hard ore.
