A universal concept for melting in mantle upwellings - Nature
High-pressure multi-anvil experiments simulate volatile-bearing mantle melting at 7 GPa and 1,420–1,630°C using CO2–graphite buffering and Re/Pt capsules.
Earth's core may contain 45 oceans' worth of hydrogen
Earth's core may contain up to 45 oceans' worth of hydrogen, indicating formation from a hydrogen-rich protoplanetary disk and primordial retention of water.
