Bridgmanite, the most abundant mineral in Earth
Silicate perovskite is the term given to (Mg,Fe)SiO3 (also known as bridgmanite[1]) and CaSiO3 (calcium silicate) when arranged in a perovskite structure.Silicate perovskites are mainly found in the lower part of Earth's mantle, between about 670 and 2,700 km (420 and 1,680 mi). They are thought to form the main mineral phases, together withferropericlase.
Meteorites exposed to high pressures and temperatures during impact-induced shock often contain minerals whose occurrence and stability normally confine them to the deeper portions of Earth’s mantle. One exception has been MgSiO3 in the perovskite structure, which is the most abundant solid phase in Earth. Here we report the discovery of this important phase as a mineral in the Tenham L6 chondrite and approved by the International Mineralogical Association (specimen IMA 2014-017). MgSiO3-perovskite is now called bridgmanite. The associated phase assemblage constrains peak shock conditions to ~ 24 gigapascals and 2300 kelvin. The discovery concludes a half century of efforts to find, identify, and characterize a natural specimen of this important mineral.
