- Many minerals are stable over a limited range of temperature and pressure. Changes in these two variables cause a mineral to react and form a new mineral or minerals.
- Laboratory experiments conducted with different minerals and at measured temperatures and pressures reveal the conditions where metamorphic minerals are stable.
