The oolites of intact iron ore were composed of goethite (α-FeOOH), with siderite (FeCO 3) and phyllosilicates as cement. Oolites of the aged iron ore contained hematite (α-Fe 2 O 3), as well as goethite and significantly less siderite. We observed that 26% and 20% of goethite was bio-reduced for aged and intact iron ore respectively.
