Zinc isotope composition of the Earth and its behaviour during planetary accretion
TLDR
In this article, the authors report data for 40 ultramafic rocks comprising pristine upper mantle peridotites from the Balmuccia orogenic lherzolite massif and Archean komatiites that together define the Zn isotope composition of the Earth's primitive mantle.About:

Magnesium isotope evidence that accretional vapour loss shapes planetary compositions
Remco C. Hin,Christopher D. Coath,Philip J. Carter,Francis Nimmo,Yi-Jen Lai,Philip A.E. Pogge von Strandmann,Matthias Willbold,Zoë M. Leinhardt,Michael J. Walter,Tim Elliott +9 more
TL;DR: In this paper, it was shown that all differentiated planetary bodies have isotopically heavier magnesium compositions than chondritic meteorites, and that the magnesium isotope fractionation during condensation of the solar nebula, core formation and silicate differentiation cannot explain these observations.

Evaporation of moderately volatile elements from silicate melts: experiments and theory
Paolo A. Sossi,Stephan Klemme,Hugh St. C. O'Neill,Jasper Berndt,Frédéric Moynier,Frédéric Moynier +5 more
TL;DR: In this paper, a series of experiments in which silicate liquids are evaporated in one-atmosphere (1-atm) gas-mixing furnaces under controlled f O 2 s, from the Fe-“FeO” buffer (iron-wustite, IW) to air (10 -0.68 bars), bracketing the range of most magmatic rocks.
The Mass-Dependence of Cadmium Isotope Fractionation During Evaporation
TL;DR: In this paper, the mass-dependence of the mass fractionation line in linearized three-isotope space is investigated by measuring the isotope ratios of a fractionated product relative to the starting material.

Zinc isotopic systematics of Kamchatka-Aleutian arc magmas controlled by mantle melting
TL;DR: In this paper, the authors have determined Zn isotopic compositions of 37 well-characterized arc rocks from the Kamchatka and Central-Eastern Aleutian arcs, which record contributions of fluids and melts derived from altered oceanic crust (AOC) without overprints of sediment melts.

Solar System Abundances and Condensation Temperatures of the Elements
TL;DR: In this article, solar photospheric and meteoritic CI chondrite abundance determinations for all elements are summarized and the best currently available photosphere abundances are selected, including the meteoritic and solar abundances of a few elements (e.g., noble gases, beryllium, boron, phosphorous, sulfur).

Trace element fractionation during anatexis
TL;DR: The theoretical basis of trace element fractionation presented in a paper by P. W. Gast (1968) can be developed in a more flexible algebraic form, which is described and illustrated in this article.

Cosmochemical Estimates of Mantle Composition
TL;DR: The composition of the primitive mantle derived by as mentioned in this paper shows that Earth was assembled from material that shows many of the same chemical fractionation processes as chondritic meteorites. But the stable isotope record excludes chondrite meteorites as the ‘building blocks’ of Earth.

Compositions of chondrites
TL;DR: In this article, a compilation of data on 78 elements in the nine groups of chondrites shows each to be isochemical with the exception of a few volatiles, and the most volatile elements have solar abundances to within a factor of two.

Applying Stable Isotope Fractionation Theory to New Systems
TL;DR: Theoretical estimates of isotope fractionations are particularly powerful in systems that are difficult to characterize experimentally, or when empirical force field calculations and ab initio quantum chemistry are needed as discussed by the authors.
