The Earth’s interior is an extreme environment where the pressure and temperature (up to 3.6 Mbar or 360 GPa, and approximately 6000 K, respectively at Earth’s center) are sufficiently high to affect the structure, physics, and chemistry of minerals in often surprising ways that may confound our intuition based on studies at near-ambient conditions. Though the Earth’s interior deeper than 12 km has not been subject to in situ observation, observational evidence from seismology, combined with experimental and theoretical studies of Earth materials under extreme conditions, has allowed us to construct a picture of this remote region of the planet...
