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.

Siderite is some shade of brown or brownish yellow. It is more dense (3.96) than other common carbonates because of iron content. It occurs as an earthy mass or as concretionary nodules (clay ironstone) in iron-rich sedimentary rocks. Crystals form in hydrothermal veins and it may be found in banded iron formations from the Precambrian.

Siderite crystals have a rhombohedral shape and often occur as aggregates or clusters. It has a hardness of 3.5-4 on the Mohs scale, which means it is relatively soft and can be scratched with a knife. Siderite has several uses, both industrial and decorative. It is an important source of iron ore and can be used to produce pig iron and steel.
