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.

Abstract: The composition of the primitive mantle derived here shows that Earth was assembled from material that shows many of the same chemical fractionation processes as chondritic meteorites. These processes occurred at the initial stage of the solar system formation, under conditions thought to be present in the solar nebula. But the stable isotope record excludes chondritic meteorites as the ‘building blocks’ of Earth. Meteorites formed in local environments separated from that part of the inner solar system where much of the material forming the terrestrial planets was sourced.

The chemical-temporal evolution of lithospheric mantle underlying the North China Craton
TL;DR: In this paper, a view into both the Paleozoic and modern SCLM underlying the North China Craton (NCC) underlying the NCC was examined, and mantle xenoliths and xenocrystic chromites were extracted from three Pale-ozoic kimberlites (Tieling, Fuxian and Mengyin), and mantle Xenomorphs from one Cenozoic basaltic center (Kuandian).

Zn/Fe systematics in mafic and ultramafic systems: Implications for detecting major element heterogeneities in the Earth’s mantle
TL;DR: In this paper, the authors report Zn, Mn and Fe systematics in mafic and ultramafic systems (whole-rocks and minerals) and explore their use for detecting lithological heterogeneities that deviate from peridotitic mantle dominated by olivine and orthopyroxene.

Fractionation of the platinum-group elements during mantle melting.
TL;DR: Experiments in sulfide-silicate systems demonstrate that two sulfide phases are stable in the asthenospheric upper mantle: a crystalline osmium-iridiumruthenium-enriched monosulfide and a rhodium-platinum-palladium–enriched sulfide melt.

Variations of Li and Mg isotope ratios in bulk chondrites and mantle xenoliths
Philip A.E. Pogge von Strandmann,Tim Elliott,Horst R. Marschall,Horst R. Marschall,Christopher D. Coath,Yi-Jen Lai,A. Jeffcoate,Dmitri A. Ionov +7 more
TL;DR: In this article, the authors present whole rock Li and Mg isotope analyses of 33 ultramafic xenoliths from the terrestrial mantle, which they compare with analyses of 30 (mostly chondritic) meteorites.

Dejan Prelević,Dejan Prelević,Cüneyt Akal,Stephen F. Foley,Rolf L. Romer,Andreas Stracke,P. van den Bogaard +6 more
TL;DR: In this article, the Menderes Massif has been studied for lamproitic volcanic rock occurrences of high-Mg ultrapotassic affinity, showing increasingly younger ages ranging from 20 to 4 Ma.

The continental crust: Its composition and evolution
Stuart Ross Taylor,Scott M. McLennan +1 more
- 01 Jan 1985
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

LIII. On lines and planes of closest fit to systems of points in space
TL;DR: This paper is concerned with the construction of planes of closest fit to systems of points in space and the relationships between these planes and the planes themselves.
The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.
