Overview

Silicate perovskite is either (Mg,Fe)SiO3 (the magnesium end-member is called bridgmanite) or CaSiO3 (calcium silicate, known as davemaoite) when arranged in a perovskite structure. Silicate perovskites are not stable at Earth's surface, and mainly exist in the lower part of Earth's mantle, between about 670 and 2,700 km (420 and 1,680 mi) depth. They are thought to form the main mineral phases of the lower mantle, together with ferropericlase.
