Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series.
42.
It commonly occurs with galena, tetrahedrite, sphalerite, chalcopyrite, pyrite, stibnite, zinkenite, siderite, quartz, rhodochrosite, dolomite and barite.
43.
Associated minerals include : adamite, paradamite, kottigite, scorodite, smithsonite, leiteite, renierite, pharmacosiderite, aurichalcite, siderite, goethite and pyrite.
44.
Limonite pseudomorphs have also been formed from other iron oxides, hematite and magnetite; from the carbonate siderite and from iron rich silicates such as almandine garnets.
45.
Next to a hematite deposit owned by Algoma was a mountain more than 1, 000 feet high but it contained a low-grade ore called siderite.
46.
It was first described for an occurrence in Wheal Boys in the parish of St Endellion in Cornwall, it was found associated with jamesonite, sphalerite and siderite.
47.
In the 18th and 19th centuries, the clays of the Muirkirk Deposit in Prince George's County, Maryland were mined for siderite, or iron ore.
48.
They can also contain the following particles at less than 63 micrometres : calcite, dolomite, siderite, pyrite, marcasite, heavy minerals, and even organic carbon.
49.
Siderite or pyrite coatings are also occasionally observed on the wall of the cavities present in the septaria, giving rise respectively to a panoply of bright reddish and golden colors.
50.
The area is known to contain quartz, siderite, and calcite crystal deposits and one such item is on display in Sarajevo at the National Museum of Bosnia and Herzegovina.
