Mar 01, 2018  In finely laminated carbonate beds (Fig. 13A), clusters of brown ankerite rhombs that overprint the fine-grained siderite (Fig. 13B, C) preserve abundant minute particles of magnetite and hematite (Fig. 13D, E). The iron oxide particles are concentrated in the ankerite rhombs, which appear to have been oxidized in preference to siderite.

Siderite - Wikipedia

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.

Siderite - Mineral Properties, Photos and Occurence

Nov 22, 2018  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.

Siderite SpringerLink

Siderite is found in banded iron formations of different ages, the oldest being at Isua, West Greenland (ca. 3.8 Ga). The occurrence of siderite is considered an index of intermediate oxidation conditions, compared to that in sulfide-facies (reducing conditions) and hematite-magnetite facies iron formations (oxidizing conditions).
