Siderite chemical formula is FeCO3, its a simple iron (II) carbonate. Siderite has the trigonal crystal symmetry, usually crystallizing as rhombohedra. The crystals typically occur with curved faces, sometimes resulting in the form of lens-shaped or bladed crystals. The specimens are also well-known for exhibiting saddleshapes…

An early and historical method, where meteorite, magnetite, native iron, siderite and pyrite samples were dissolved and converted into iron sulfate, was developed by Valley & Anderson (1941, 1947) Valley & Anderson (1941) Valley & Anderson (1947). Iron isotopes (54 Fe, 56 Fe, 57 Fe, 58 Fe) were measured on a mass spectrograph (Figure 12-7.3).

Excellent historic specimen showing large crystals of fresh green siderite, but covered with a fine veil of large brown iron oxides. A few rare breaks are present on the piece, which is usual for this type of specimen extracted at the end of the 19th century from the mine then in operation, by a miner looking for a "drink", in secret from his employer.

Using an open pit mining method, the mine had a capacity of extracting 111,766 metric tons of ore per day in 1987, with a production unit cost of $2.08 per metric ton of ore. The ore extracted from the Minntac Iron Mine primarily consists of siderite, magnetite, and ankerite, while the waste material predominantly consists of chert and calcite.

In iron-bearing reducing settings on the Earth's surface and in the shallow subsurface, siderite is the most common iron carbonate mineral (Hangari et al., 1980; Mulders et al., 2021).Siderite is formed by complicated interactions between iron and organic materials precipitated during quasi-syngenesis (Wittkop et al., 2014).Most often, siderite is formed in …

Iron in the siderite was not only derived from silicate weathering of high-Ti basalts in the sediment source regions followed by transport as ions by ground and surface waters, but was also generated from in situ alteration of the Fe-bearing minerals within the peat itself. In addition, ascending hydrothermal solutions would also contribute some Fe, with the Fe …
