Abstract We have carried out in situ high‐pressure acoustic velocity measurements of (Fe2+, Al)‐bearing MgSiO3 glass up to pressures of 155 GPa, which confirmed a distinct pressure‐induced trend change in the transverse acoustic velocity (VS) p

The iron isotope composition of Earth’s mantle requires planetary growth within 5 Ma of solar system formation.
Nucleosynthetic isotope variability among solar system objects provides insights into the accretion history of terrestrial planets.
