of iron from ilmenite during weathering can result in poorly crystalline mineral grains residually enriched in TiO2. The term ilmenite commonly covers the entire range from unweathered ilmenite (TiO2 <50%) to altered ilmenite (TiO2 >60%). When the TiO2 content of altered ilmenite exceeds about 70%, it is commonly referred to as leucoxene.
