Composition and state of the core

K Hirose, S Labrosse, J Hernlund - Annual Review of Earth and …, 2013 - annualreviews.org
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 …

Density-functional perturbation theory for quasi-harmonic calculations

S Baroni, P Giannozzi, E Isaev - Reviews in Mineralogy …, 2010 - pubs.geoscienceworld.org
Computer simulations allow for the investigation of many materials properties and processes
that are not easily accessible in the laboratory. This is particularly true in the Earth sciences …

Melting of iron at Earth's inner core boundary based on fast X-ray diffraction

S Anzellini, A Dewaele, M Mezouar, P Loubeyre… - Science, 2013 - science.org
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 …

The structure of iron in Earth's inner core

S Tateno, K Hirose, Y Ohishi, Y Tatsumi - Science, 2010 - science.org
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 …

Electrical resistivity and thermal conductivity of liquid Fe alloys at high P and T, and heat flux in Earth's core

N De Koker, G Steinle-Neumann… - Proceedings of the …, 2012 - National Acad Sciences
Earth's magnetic field is sustained by magnetohydrodynamic convection within the metallic
liquid core. In a thermally advecting core, the fraction of heat available to drive the …

Melting curve of iron to 290 GPa determined in a resistance-heated diamond-anvil cell

R Sinmyo, K Hirose, Y Ohishi - Earth and Planetary Science Letters, 2019 - Elsevier
The Earth's core is composed mainly of iron. Since the liquid core coexists with solid at the
inner core boundary (ICB), the melting point of iron at 330 GPa offers a key constraint on …

Melting in the Fe–C system to 70 GPa

OT Lord, MJ Walter, R Dasgupta, D Walker… - Earth and Planetary …, 2009 - Elsevier
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 …

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

Y Zhang, K Luo, M Hou, P Driscoll… - Proceedings of the …, 2022 - National Acad Sciences
Light elements in Earth's core play a key role in driving convection and influencing
geodynamics, both of which are crucial to the geodynamo. However, the thermal transport …

[HTML][HTML] Thermodynamics and equations of state of iron to 350 GPa and 6000 K

PI Dorogokupets, AM Dymshits, KD Litasov… - Scientific reports, 2017 - nature.com
The equations of state for solid (with bcc, fcc, and hcp structures) and liquid phases of Fe
were defined via simultaneous optimization of the heat capacity, bulk moduli, thermal …

Shock compression of stishovite and melting of silica at planetary interior conditions

M Millot, N Dubrovinskaia, A Černok, S Blaha… - Science, 2015 - science.org
Deep inside planets, extreme density, pressure, and temperature strongly modify the
properties of the constituent materials. In particular, how much heat solids can sustain before …
