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…

Siderite forms in oxygen-deficient environments when ferrous iron reacts with carbonate ions. The mineral is a sedimentary precipitate, meaning it forms when the minerals in water precipitate. This mineral can also form inside metamorphic rocks. Most often, you'll find siderite in sedimentary deposits, hydrothermal veins, and banded iron beds.

The composition of the roasted products of siderite is determined by the roasting atmosphere [15]. In an inert atmosphere, siderite first decomposes to form wustite (FeO) and CO 2 (FeCO 3 → FeO + CO 2), and then the wustite and CO 2 react to form magnetite (Fe 3 O 4) and CO (FeO + CO 2 → Fe 3 O 4 + CO) [15]. The roasted product is a mixture of magnetite and …

Siderite is a carbonate mineral composed primarily of iron(II) carbonate (FeCO₃). It is significant both economically and geologically, often found in sedimentary iron deposits and playing a vital role in the formation of iron ore. The presence of siderite can indicate specific environmental conditions during its formation, linking it to processes such as diagenesis and metamorphism.

Siderite is a significant component of the Ordovician bedded ironstones exposed across North Wales from Cadair Idris to Anglesey (Pulfrey, 1933). In South Wales, it is the principal carbonate mineral in the clay-ironstone nodule beds of Upper Carboniferous age which occur within the South Wales Coalfield (North, 1916; Firth, 1971).

Siderite and clay minerals are the main authigenic constituents in ironstones of the Bakchar deposit. Siderite is classified into two varieties (Fig. 3). Siderite I is the most dominant type and shows a low content of Σ(MnO + MgO + CaO) up to 5.6%. It shows primary fluid inclusions having 2–6 μm diameter.
