The principal accessory minerals are titaniferous iron oxides and apatite.
titaniferous iron ores, extensive deposits of which are known in many places, usually contain a small percentage of vanadium.
The titaniferous magnetites constitute a widely distributed but at present commercially unavailable class of iron ores.
The titaniferous oxide of iron, or iron sand, is also attractable by the magnet.
It was found to contain good crystals of augite and olivine, well striated labradorite, and titaniferous iron ore.
