What Is Martite?
Martite is a mineralogical variety of hematite that forms as a pseudomorph after magnetite. This means that martite retains the original crystal shape of magnetite but has been chemically altered into hematite, typically through oxidation. It commonly preserves the cubic or octahedral crystal habit of magnetite, resulting in sharply defined forms with a metallic to submetallic luster.
Martite is typically dark steel-gray to reddish-black in color and has a hardness of about 5.5 to 6.5 on the Mohs scale. It is often found in iron ore deposits, especially those subjected to weathering or hydrothermal alteration. Notably, it can occur in massive forms or as sparkling granular aggregates, and is frequently associated with other iron oxide minerals. Martite is valued both for its role in iron ore geology and as an attractive mineral specimen.
