Hot Enough to Melt Iron Earth's core is divided into a fluid outer core and a solid inner core, both composed predominately of iron at extremely high pressures and temperatures. The boundary between these two regions is largely controlled by the melting point of iron at ∼330 GPa, which in turn influences heat transfer and geodynamo generation. Anzellini et al. (p. 464, see the Perspective by Fei) compressed iron in a laser-heated diamond anvil cell, tracking its structure and texture by using… 

Shock Melting Curve of Iron: A Consensus on the Temperature at the Earth's Inner Core Boundary

The Earth's core consists of iron as the major component. The melting point of iron at the inner core boundary constrains the thermal structure and solidification of the Earth's core. However, the

Melting Earth's Core

The accurate determination of the melting temperature of iron provides an important constraint on the core temperature, which is essential to understanding how the dynamic Earth works, including its heat budget, generation of its magnetic field, and the thermal evolution of the planet.

Thermal conductivity of Fe-Si alloys and thermal stratification in Earth’s core

A near temperature independence of the resistivity in iron-silicon alloys at Earth core’s pressure and thus a high thermal conductivity is found, indicating that if silicon is the sole major light element in Earth's core it could depress thermal convection and promote a thermally stratified layer at the topmost outer core.

Measuring the melting curve of iron at super-Earth core conditions

High-energy lasers at the National Ignition Facility and in situ x-ray diffraction are used to determine the melting point of iron and the length of dynamo action during core solidification to the hexagonal close-packed structure, finding that terrestrial exoplanets with four to six times Earth's mass have the longest dynamos.

Melting of Fe Alloys and the Thermal Structure of the Core

The Earth’s core consists primarily of iron‐nickel alloy. The presence of several weight percent of one or more lighter elements such as S, Si, O, C, or H is implied by the core’s density, and these

Viscosity of hcp iron at Earth’s inner core conditions from density functional theory

It is shown that dislocation creep is a key mechanism driving deformation of hcp iron at inner core conditions, and the associated viscosity agrees well with the estimates from geophysical observations supporting that the inner core is significantly less viscous than the Earth’s mantle.

Low Core-Mantle Boundary Temperature Inferred from the Solidus of Pyrolite

The experimentally determined maximum melting point of 3570 kelvin suggests that some phases typically thought to lose stability in the lowermost mantle, such as MgSiO3-rich post-perovskite, may be more widely distributed than expected.

Melting curve of iron up to 3600 kbar by statistical moment method

Abstract The inner core of the earth is solid, the outer liquid is composed mainly of iron, and the pressure at the inner core boundary (ICB) is 3300 kbar (330 GPa). The melting point of iron at ICB

Evidence for Fe-Si-O liquid immiscibility at deep Earth pressures

High-pressure immiscibility in the Fe-Si-O system may explain a stratified layer atop the outer core, complicate differentiation and evolution of the deep Earth, and affect the structure and intensity of Earth’s magnetic field.



Melting of iron at the physical conditions of the Earth's core

New and re-analysed sound velocity measurements of shock-compressed iron at Earth-core conditions show that melting starts at 225±3 GPa and is complete at 260 ± 3‬GPa, both on the Hugoniot curve—the locus ofshock-compression states.

Temperatures in the Earth's core from melting-point measurements of iron at high static pressures

THE temperature distribution in the Earth's core places important constraints on the Earth's internal heat budget and on models of the geodynamo. The solid inner core crystallizes from a liquid outer

Melting of the Earth’s inner core

Here geodynamo simulations are used to show that variations in heat flow from mantle convection are transferred to the inner-core boundary and can be large enough to cause heat to flow into the inner core.

Temperature of the inner-core boundary of the Earth: Melting of iron at high pressure from first-principles coexistence simulations

The Earth's core consists of a solid ball with a radius of 1221 Km, surrounded by a liquid shell which extends up to 3480 km from the center of the planet, roughly half way toward the surface (the

Thermal and electrical conductivity of iron at Earth’s core conditions

New estimates indicate that the adiabatic heat flux is 15 to 16 terawatts at the CMB, higher than present estimates of CMB heat flux based on mantle convection; the top of the coremust be thermally stratified and any convection in the upper core must be driven by chemical convection against the adverse thermal buoyancy or lateral variations in CMBHeat flow.

The Melting Curve of Iron to 250 Gigapascals: A Constraint on the Temperature at Earth's Center

The melting curve of iron, the primary constituent of Earth's core, has been measured to pressures of 250 gigapascals with a combination of static and dynamic techniques and results imply that the temperature of the lower mantle is significantly less than that of the outer core.

The Structure of Iron in Earth’s Inner Core

Packing the Core The packing and arrangement of atoms in Earth's solid inner core can dictate processes such as core growth and rotation. Seismology and modeling suggest the inner core is composed

Melting of iron under Earth's core conditions from diffusion Monte Carlo free energy calculations.

The temperature of Earth's core is a parameter of critical importance to model the thermal structure of Earth. Since the core is mainly made of iron, with a solid liquid boundary (the inner core

Shock temperatures and melting of iron at Earth core conditions.

The temperature of shock compressed iron has been measured to 340 GPa, using well characterized iron films sputtered on transparent diamond substrates and a 1 ns time-resolved optical method. We find
