The Hematite Group is a more or less informal group of closely related trigonal oxides.Their relationship is linked through their similar structures. The general formula for this group is A 2 O 3. The A cations can be either iron, titanium, aluminum, chromium, vanadium, magnesium, antimony, sodium, zinc and/or manganese. (The structure is composed of alternating layers of cations and oxygens.
