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 ankeritedolomite in the Kidd Creek tailings impoundment at Timmins, Ontario, Canada (Al et al., 2000).
