Earth’s deep mantle was drier from the start

Geoscientist Rita Parai in Arts & Sciences uses noble gas isotopes to better understand the formation and evolution of planetary bodies. Her new modeling study published in PNAS shows that the deep mantle had low concentrations of volatiles like xenon and water when it formed, setting up an internal viscosity contrast with lasting impacts.
