Siderite is an iron carbonate in the calcite group of similar carbonate minerals. The siderite formula is FeCO3. It forms a series with rhodochrosite, with siderite on the iron-dominant end and rhodochrosite on the manganese-dominant end. Zinc-dominant smithsonite and magnesium-dominant magnesite are also in individual series with siderite.

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. ASHLAND COUNTY: Siderite is a common …

Siderite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series. All members of the calcite group crystallize in the trigonal system, and have perfect rhombohedral ...
