Siderite

Like the precipitation of secondary Al(OH) 3, that of secondary siderite [FeCO 3] is widely employed in geochemical models. Secondary siderite and associated iron oxyhydroxides were determined to have formed as coatings, up to 1,000 μm thick, on ankerite-dolomite in the Kidd Creek tailings impoundment at Timmins, Ontario, Canada (Al et al., 2000).
