perovskite model

views updated

perovskite model A theoretical model of the Earth's composition suggesting that the mineral perovskite (CaTiO3) makes up most of the lower part of the mantle between 600 and 2800 km depth, at 2000–2500°C. Perovskite has been made artificially by compressing olivine, pyroxene, and garnet, and has been shown to withstand temperatures of 2000°C in the laboratory.
