Pressure profoundly alters all states of matter. The symbiotic development of ultrahigh-
pressure diamond anvil cells, to compress samples to sustainable multi-megabar pressures; …

Earth's core is known to be metallic, with a density of about 9.90 Mg· m− 3 at the coremantle
boundary and as such is substantially denser than the surrounding mantle (5.56 Mg· m− 3 at …

We determined high-pressure melting curves for Fe3C, Fe7C3 and the Fe–Fe3C eutectic
using laser-heated diamond anvil cell techniques. The principal criterion for melting is the …

Geochemical, cosmochemical, geophysical, and mineral physics data suggest that iron (or
iron–nickel alloy) is the main component of the Earth's core,,. The inconsistency between the …

Earth's inner core is known to consist of crystalline iron alloyed with a small amount of nickel
and lighter elements, but the shear wave (S wave) travels through the inner core at about …

Compressional wave velocity-density (VP-ρ) relations of candidate Fe alloys at relevant
pressure-temperature conditions of the Earth's core are critically needed to evaluate the …

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 solid inner core of Earth is predominantly composed of iron alloyed with several percent
Ni and some lighter elements, Si, S, O, H, and C being the prime candidates. To establish …

Abstract Knowledge of the sound velocity of core materials is essential to explain the
observed anomalously low shear wave velocity (VS) and high Poisson's ratio (σ) in the solid …

Carbon is a plausible light element candidate in the Earth's core owing to its cosmic
abundance and its chemical affinity for iron. Recent experimental studies on Fe‐C phase …
