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.
