It is relatively stable under surface soil conditions, but may weather to different secondary minerals. There is some speculation, based mainly on studies of the magnetic properties of soils, that fine-grained magnetite may form in soils. Magnetotopic bacteria have been shown to produce magnetite under appropriate conditions.

There are different levels of magnetic susceptibility of rocks. Highly magnetic rocks are ironstone and serpentinite – rocks that are highly enriched in magnetite minerals. Magnetic properties of rocks form at the earliest stages of rock formation. As magma or lava cools, magnetic minerals begin to form.

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.
