Early man made tools and weapons from the iron ore they extracted from the earth and refined. Only meteorites carry pure iron ore, and the deposits locked away within the Earth require mining andIron Ore Deposits - Windows to the UniverseIn particular, iron, sulfur, and manganese are readily attacked by oxygen. As molecular oxygen began to be produced by early autotrophs, a curious phenomena occured. Large amounts of iron which had accumulated in the early ocean as both FeSO 4 - and a solid FeS 2 (pyrite) from naturally occuring weathering and as a product of heterotrophic activity, were attacked by the accumulating O 2 .
