This means that chemical weathering transforms the crystals of pyrite into limonite by hydrating the molecules, but the external shape of the pyrite crystal remains. 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.

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

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 ...

evident as magnetite. 3.5. Pyrrhotite/Pyrite/Siderite + (Magnetite) + Hematite/Martite For Martite-ochreous Goethite (M-oG) ores, the sharp susceptibility increases at temperatures of 400˚C to 550˚C in the heating curves, shown on Figure 5, may indicate the chemical conversion of pyrite/pyrrhotite or siderite to magnetite.
The former siderite grain has a mineralogical zonation inwards, with euhedral pyrite and pyrite clusters (Fig. 2b) on the rim, a zone of pyrrhotite needles, and then a zone of μm sized euhedral magnetite towards the core. In some experiments, siderite still exists as remnants in core regions.
Siderite is a common mineral and is found worldwide in many different environments. Only the most noteworthy will be mentioned here. Classic Siderite occurrences in Europe include Neudorf in the Harz Mountains, Germany; and Panasqueira, Portugal. Excellent gemmy greenish crystals come from Isere, (especially at Allevard), France.
THERMAL DECOMPOSITION OF SIDERITE–PYRITE … the original siderite and pyrite transformed pseudomorphically to magnetite and pyrrhotite, respectively (not shown). A small S concentration was detected even among magnetite grains; this S may be adsorbed on the surfaces of magnetite grains or be very fine-grained pyrrhotite.
The magnetic mineral assemblage comprises stoichiometric magnetite, greigite, and fine‐grained pyrrhotite. The pyrite content is generally reduced in the gouge compared to the wall rock. The magnetic mineral assemblage in the gouge consists of goethite, pyrrhotite, and partially oxidized magnetite.
Within narrow ranges of Eh-pH several pairs of iron minerals are stable together: magnetite-hematite, goethite-siderite, magnetite-siderite, siderite-pyrite 5,12,14. The Figure 3 shows two areas indicated by A and B. The A area is the field domain for vivianite and B for siderite stabilitiy.

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.
Limonite has been known to form pseudomorphs after other minerals such as pyrite, meaning that the chemical weathering transforms the crystal of pyrite into limonite but keeps the external shape of the pyrite crystal. It has also been formed from other iron oxides, hematite and magnetite; the carbonate siderite and iron rich silicates like some ...

Suboxic soils and sediments often contain the Fe(II)-bearing minerals mackinawite (FeS), siderite (FeCO3) or magnetite (Fe3O4), which should be able to reduce aqueous selenite, thereby forming solids of low solubility. While the reduction of selenate or selenite to Se(0) by green rust, pyrite and by Fe2+ sorbed to montmorillonite is a slow (weeks), kinetically limited redox reaction as ...
