  • Siderite

    The most common iron carbonate is siderite(FeCO3), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K (Housen et al., 1996), distinctively different from that of pyrrhotite (Section 5.08.3.9). Siderite is paramagnetic at ordinary temperatures and carries no NRM.
