Constraining the core's composition is essential for understanding Earth accretion, core
formation and the sustainment of Earth's magnetic field. Earth's outer and inner core exhibit …

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 …

Earth's core is structured in a solid inner core, mainly composed of iron, and a liquid outer
core. The temperature at the inner core boundary is expected to be close to the melting point …

Earth continuously generates a dipole magnetic field in its convecting liquid outer core by a
self-sustained dynamo action. Metallic iron is a dominant component of the outer core, so its …

Earth's solid inner core is mainly composed of iron (Fe). Because the relevant ultrahigh
pressure and temperature conditions are difficult to produce experimentally, the preferred …

The distributions of major and minor elements in Earth's core and mantle were primarily
established by high pressure, high temperature metal–silicate partitioning during core …

Cementite occurs in steels, in meteorites, possibly at the core of the Earth and has uses in its
pure form. It's composition can deviate from F e 3 C, but not by much because the Fe–C …

We measured the electrical resistivity of iron and iron-silicon alloy to 100 GPa. The resistivity
of iron was also calculated to core pressures. Combined with the first geophysical model …

The nature and extent of Earth's deep carbon cycle remains uncertain. This chapter
considers high-pressure carbon-bearing minerals, including those of Earth's mantle and …

Hexagonal close-packed iron (hcp-Fe) is a main component of Earth's inner core. The
difference in density between hcp-Fe and the inner core in the Preliminary Reference Earth …
