Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger The origin of iron can be ultimately traced to the formation through nuclear fusion in stars, and most of the iron is thought to have originat
