The process continued for nearly a billion years and eventually let to the accumulation of oxygen in the atmosphere. Resources. Most of the world's important iron ore resources occur in banded iron formations, which are almost exclusively of Precambrian age (i.e. greater than 541 million years old). BIFs occur on all continents.
