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.

Geochemical distribution of the elements - Britannica.com

Geochemical distribution of the elements. Knowledge of the geochemical distribution of elements involves elucidation of the relative and absolute abundances of the stone elements in the Earth and in its various parts—the crust, interior, atmosphere, and hydrosphere. This comprises a major part of the science of geochemistry, which is the study of the distribution of the stone elements ...
