Post-perovskite (pPv) is a high-pressure phase of magnesium silicate (MgSiO3). It is composed of the prime oxide constituents of the Earth's rocky mantle (MgO and SiO2), and its pressure and temperature for stability imply that it is likely to occur in portions of the lowermost few hundred km of Earth's mantle.

Breyite is a high pressure calcium silicate mineral (CaSiO3) found in diamond inclusions. It is the second most abundant inclusion after ferropericlase, for diamonds with a deep Earth origin. Its occurrence can also indicate the host diamond's super-deep origin. This mineral is named after German mineralogist, petrologist and geochemist Gerhard P.
