Massive siderite of brown color with typical flashes of the mineral.
Siderite is one of the main iron minerals known since prehistoric times. It is a mineral of economic importance for the extraction of iron since it contains almost 60% iron in its pure state. It is also found in space and on satellites like the Moon or in meteorites.
