Siderite - an overview ScienceDirect Topics

The earth's core is composed of metallic iron, and iron compounds form 1.5% of the lithosphere, making iron the eighth most abundant element. The most common iron mineral is hematite (Fe 2 O 3), with magnetite (Fe 3 O 4), siderite (FeCO 3), limonite (FeO(OH)) and iron pyrites (Fool's gold, FeS 2) also widely distributed. At neutral pH, aerial ...

Wisconsin Geological Natural History Survey » Siderite

The siderite iron ore there occurred with a host of minerals, many well-crystallized, including manganite, rhodochrosite, pyrolusite, and manganoan calcite (Dickey, 1938; LaBerge,1984). — Siderite occurs with magnetite and hematite in drill core and small pits in the Pine Lake area in sec. 23, 26, 27, and 28 T.44N.

Siderite - Mineral Properties, Photos and Occurence

2018-11-22  Siderite is a member of calcite group minerals, which have a similar structure and form several solid-solution series. The miscibility of the calcite group members is limited though. Of the several possible members of the solid-solution series associated with siderite (FeCO 3), only the smithsonite (ZnCO 3), magnesite (MgCO 3) and rhodochrosite (MnCO 3) varieties are common.
