Sound velocity of CaSiO₃ perovskite suggests the presence of basaltic crust in the Earth's lower mantle, Published online: 09 January 2019; doi:10.1038/s41586-018-0816-5

In situ high-pressure and high-temperature measurements of the sound velocity of CaSiO3 perovskite suggest accumulation of basaltic crust in the Earth's uppermost lower mantle.
