The correct answer is Siderite. Siderite is a mineral composed of iron(II) carbonate (FeCO 3). Siderite is also called chalybite. Siderite has been used as iron ore and for steel production. Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites.
