Evidence of denser MgSiO(3) glass above 133 gigapascal (GPa) and implications for remnants of ultradense silicate melt from a deep magma ocean
Ultralow velocity zones are the largest seismic anomalies in the mantle, with 10–30% seismic velocity reduction observed in thin layers less than 20–40 km thick, just above the Earth’s core-mantle boundary (CMB). The presence of silicate melts, possibly a remnant of a deep magma ocean in the early E...
