Our results show that the hematite ore bodies formed at sites of repeated focussed hydrothermal fluid flow. In contrast to the aforementioned models, our results imply that iron-ore formation was probably a long-lived, multi-stage process spanning more than one billion years.

An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.
