Magnetite - Wikipedia

Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a bufferthat can control how oxidizing its environment is (the oxygenfugacity). This buffer is known as the hematite-magnetite or HM buffer. At lower oxygen levels, magnetite can form a buffer with quartzand fayaliteknown as the QFM buffer.
