Carbon in the core
TLDR
In this article, it was shown that carbon volatility is a strongly pressure-dependent phenomenon and that it applies during condensation from a solar gas ( ∼ 10−3 atm), but not at the pressures and temperatures generated during planetary accretion and differentiation (0.01-5 GPa).About:

The Redox State of Earth's Mantle
TL;DR: In this article, the upper mantle oxygen fugacity at the top of the spinel peridotite rocks is shown to fall within 2 log units of the fayalite-magnetite-quartz (FMQ) oxygen buffer.
Journal ArticleDOI
The deep carbon cycle and melting in Earth's interior
TL;DR: Carbon geochemistry of mantle-derived samples suggests that the fluxes and reservoir sizes associated with deep cycle are in the order of 1012−13−g−C/yr and 1022−23−g C, respectively.
Journal ArticleDOI
The chemical composition of the Earth
TL;DR: In this paper, the bulk composition of the Earth and the composition of its mantle and core are calculated using the ratios of major and trace elements, without resorting to assumptions about core formation processes.
Journal ArticleDOI
Light elements in the Earth's outer core: A critical review
TL;DR: In this article, the authors present ternary and quaternary phase diagrams to provide constraints on the nature of the light elements in the outer core of the Earth's core.

Compositional Model for the Earth's Core
TL;DR: The boundary between the silicate mantle and the core is remarkable in that it is a zone of greatest contrast in Earth properties as discussed by the authors, and the density increase across this boundary represents a greater contrast than across the crust-ocean surface.

Preliminary reference earth model
TL;DR: In this paper, a large data set consisting of about 1000 normal mode periods, 500 summary travel time observations, 100 normal mode Q values, mass and moment of inertia have been inverted to obtain the radial distribution of elastic properties, Q values and density in the Earth's interior.

Thermodynamic Properties of Minerals and Related Substances at 298.15 K and 1 Bar (105 Pascals) Pressure and at Higher Temperatures
TL;DR: A report about values for the entropy, molar volume, and for the enthalpy and Gibbs energy of formation for the elements and minerals and substances at 298.15 K was given in this paper.
Journal ArticleDOI
Elasticity and constitution of the Earth's interior
TL;DR: In this paper, the authors derived a general equation for the variation of the quantity,, in a homogeneous gravitating layer with an arbitrary gradient of temperature, and discussed the parameters of this equation in terms of the experimental and theoretical relations for solids.
Journal ArticleDOI
Condensation in the primitive solar nebula
TL;DR: In this article, the distribution of the major elements between vapor and solid has been calculated for a cooling gas of cosmic composition, assuming that high temperature condensates remain in equilibrium with the vapor, affecting the temperatures of appearance of successively less refractory phases.
