For the first time, a high-pressure calcium silicate perovskite (CaSiO3) has been identified as a naturally occurring mineral from Earth’s lower mantle, researchers report.

The newly discovered crystalline compound, named davemaoite by the authors, was found trapped as an inclusion inside a deep-earth diamond, which formed at high-pressure and temperature more than 660 kilometers below the Earth’s surface.

Davemaoite was named in honor of Ho-kwang (Dave) Mao – a prominent experimental high-pressure geophysicist – and confirmed as a new mineral by the International…
