Oct 05, 2016 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.

Hematite and Magnetite differ due to the different oxidation states the Iron is in. Hematite Fe2O3 tends to form in environments that are generally more oxygen-rich than Magnetite Fe304. Magnetite tends to form in environments that contain more f02, such as in more evolved magmas, and can even be formed within metamorphic rocks.
