In sedimentary rocks, hematite can either have formed from have originally formed directly from direct precipitation out of marine waters, or as a concentration and enrichment deposit formed from groundwater. Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite.

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.

The lateral transition from unaltered siderite to partially altered siderite with hematite and magnetite inclusions, to oxides comprising a hematite core and magnetite rim (Fig. 7B–F) provides compelling evidence for the replacement of pre-existing siderite and iron-silicates by magnetite and hematite.

— Magnetite occurs with hematite and siderite in the banded iron formation in the Pine Lake area, T.44N. R.3E. (U.S.G.S., 1976). — Magnetite and grunerite occur at the Ford and Lucas Whitside exploration near Butternut in sec. 2 and 4 T.41N. R.1E. (Dutton and Bradley, 1970).
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.
