The composition and state of Earth's core, located deeper than 2,900 km from the surface,
remain largely uncertain. Recent static experiments on iron and alloys performed up to inner …

This paper provides the state-of-the-art discussion of major aspects of the composition and
evolution of the Earth's core. A comparison of experimentally-derived density of Fe with …

The melting temperature of Earth's mantle provides key constraints on the thermal structures
of both the mantle and the core. Through high-pressure experiments and three-dimensional …

The Fe-H system has been investigated by combined x-ray diffraction studies and total
energy calculations at pressures up to 136 GPa. The experiments involve laser annealing of …

Hydrous minerals in subducted crust can transport large amounts of water into Earth's deep
mantle. Our laboratory experiments revealed the surprising pressure-induced chemistry that …

Eutectic melting temperatures in the Fe–FeO and Fe–Fe 3 C systems have been determined
up to 150 GPa. Melting criteria include observation of a diffuse scattering signal by in situ X …

Melting experiments were performed on the Fe–Fe 3 S system at high pressures between 34
and 254 GPa in a laser-heated diamond-anvil cell (DAC), using starting materials of fine …

We have examined the density and bulk sound velocity of liquid iron alloys,(Fe, Ni) X (H, Si,
O, S, C) 1-X, at Earth's outer core pressure and temperature conditions based on first …

We explore the partitioning behavior of hydrogen between coexisting metal and silicate
melts at conditions of the magma ocean and the current core–mantle boundary with the help …

Liquid-liquid immiscibility has been widely observed in iron alloy systems at ambient
pressure and is important for the structure and dynamics in iron cores of rocky planets. While …
