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 …

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 less dense than iron, and therefore it must contain “light elements,” such as S,
Si, O, or C. We use ab initio molecular dynamics to calculate the density and bulk sound …

The formation of Earth's core left behind geophysical and geochemical signatures in both
the core and mantle that remain to this day. Seismology requires that the core be lighter than …

Earth's inner core (IC) is less dense than pure iron, indicating the existence of light elements
within it. Silicon, sulfur, carbon, oxygen and hydrogen have been suggested to be the …

The abundance of siderophile elements in the mantle preserves the signature of core
formation. On the basis of partitioning experiments at high pressure (35 to 74 gigapascals) …

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 …

The Earth's core is comprised mostly of iron and nickel, but it also contains several weight
percent of one or more unknown light elements, which may include silicon. Therefore it is …

Investigations into the compositional model of the Earth, particularly the atypical
concentrations of volatile elements within the silicate portion of the early Earth, have …
