Bridgmanite

Uncategorized

Silicate perovskite is either (Mg,Fe)SiO3 (the magnesian end-member is called bridgmanite) or CaSiO3 (calcium silicate) 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, together with ferropericlase.
