The Tincroft mine is known for its Siderite, Torbernite and Hematite. This specimen is fabulous with perhaps two generations of Siderite, the first as an epimorphic cast over a later re-deposited lighter brown zoned Siderite. The rhombic crystals measure 8mm. David New label.
Limonite and siderite ores were recovered from open-pit mines in Cass, Cherokee, Henderson, and Morris counties. In 1985 Texas exported 1,116 short tons of iron ore to foreign countries and 22,237 short tons domestically, in addition to receiving significant imports.

Vivianite is famous for its bluish-green color. Erythrite is famous for its red-purple color, and annabergite for its apple-green color. A general formula of vivianite group minerals stands as: A2+3(XO4)2 × 8H2O, where X = P or As and A2+ = Co, Fe, Mg, Mn, Ni or Zn. Schematic representation of the structure of vivianite viewed along the b axis.

Mazon Creek Fossil Flora. The Mazon Creek fossil deposit extends over a wide area of northeastern Illinois. The fossils are best known from concretions or nodules of siderite, an iron carbonate mineral, which generally must be fractured to expose a plant or animal fossil within. These nodules occur in a geological unit known as the Francis ...

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.
Magnetite. Limonite. Siderite. The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.
