Mineral chemistry of magnetite from magnetite-apatite ...

Magnetite-apatite deposits, sometimes referred to as Kiruna-type deposits, are major producers of iron ore that dominantly consist of the mineral magnetite (nominally [Fe²⁺Fe³⁺₂]O₄). It remains unclear whether magnetite-apatite deposits are of hydrothermal or magmatic origin, or a combination of those two processes, and this has been a subject of debate for over a century.
