• Siderite - Wikipedia

    en.wikipedia.org/wiki/Siderite Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.

    hyperphysics.phy-astr.gsu.edu/hbase/Minerals/siderite.html Siderite is a member of the calcite group of carbonates along with rhodochrosite and Smithsonite. Siderite is a minor ore of iron. Its name derives from sideros, the Greek word for iron. Looking profoundly different from the sample above, this siderite is from Baia Sprie, Crisana-Maramures, Romania and measures about 12x14 cm.

    www.galleries.com/Siderite Siderite forms mostly in sedimentary and hydrothermal environments, although it is also found in some igneous pegmatites. Siderite is a common mineral although excellent, attractive crystal specimens are sometimes hard to find. But many crystals, when colorfully iridescent, make a wonderful, colorful, satiny, shimmering mineral specimen.
