Iron I

In iron formations, the amount of iron has been concentrated by weathering and leaching of non-iron minerals, such that we only use the term "iron formation" for rocks that contain >50% iron. The ore (iron) is concentrated by downward percolating water, and occurs in places where downward flowing waters are guided and converge, such as along a slanting layer of impermeable rock below.
