Siderite. Siderite is an ore of iron when found in sufficient volume to be economically recoverable. It was named in 1845 from the Greek word meaning "iron," in allusion to its composition. It is most often found in bedded sedimentary deposits with shales and coal beds and also as bog deposits. Mineral Photos courtesy of R.Weller/Cochise ...

Siderite is a mineral composed of iron carbonate . Its name comes from the Ancient Greek word σίδηρος, meaning "iron". A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus. Zinc, magnesium, and manganese commonly substitute for the iron, resulting in the siderite-smithsonite, siderite-magnesite, and siderite-rhodochrosite …
The mineral surface of natural siderite can also exhibit needle-like or granular structures, commonly associated with minerals like pebbles or quartz (Weibel et al., 2016). Relevant studies have reported that a significant number of natural siderite samples have metal ions such as Mg, Ca, and Mn, replacing Fe in their crystal lattices ...

Distribution. Siderite occurs as clay ironstone, an impure mixture of siderite with clay minerals. It may form concretions or concentric layers. It may also occur as black-band ore, which can form extensive stratified beds admixed with shales, other carbonates, and coal. Siderite is also formed as iron rich waters replace Ca in limestone.
Item Description. A showy miniature sized piece of Siderite from the limited finds at the Kaiwu Mine in Guizhou, China.

Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides.
