CHAPTER-5 GEOCHEMISTRY OF IRON ORES

2012-8-16  Iron formation facies are of oxide type, silicate type, carbonate type and sulphide type depending upon the thermodynamics (Fig.-1) of the depositional environment. The mineralogical association in these facies is given in the Table-12. It is to note that the dominant mineralogy of iron bearing phase differs (Hematite, magnetite, siderite, pyrite)

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.
