Rutile - Wikipedia

Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.
