Mantle Samples Included in Volcanic Rocks: Xenoliths and Diamonds
TL;DR: A review of the geochemistry of mantle xenoliths can be found in this article, where the authors review the geochemical properties of mantle nodules and find that they are dominantly alkaline in nature.
Journal ArticleDOI
The chemistry of hydrothermal magnetite: A review
TL;DR: The most important factors that govern compositional variations in hydrothermal magnetite are (A) temperature, (B) fluid composition, (C) oxygen and sulfur fugacity, (D) silicate and sulfide activity, (E) host rock buffering, (F) reequilibration processes, and (G) intrinsic crystallographic controls such as ionic radius and charge balance as mentioned in this paper.
Journal ArticleDOI
The crystal/melt partitioning of V during mantle melting as a function of oxygen fugacity compared with some other elements (Al, P, Ca, Sc, Ti, Cr, Fe, Ga, Y, Zr and Nb)
TL;DR: In this article, a series of 1 atm (1300 degrees C) and high-pressure (1-3 GPa, 1315-1450 degrees C), experiments were carried out over a range of redox conditions sufficiently large (from QFM-13 center dot 3 to QFM+11 center dot 4, where QFM is the quartz-fayalite-magnetite oxygen buffer) to constrain the full panoply of V chemical behaviour.

Nb/Ta and Zr/Hf in ocean island basalts — Implications for crust–mantle differentiation and the fate of Niobium
TL;DR: In this paper, high-precision Nb, Ta, Zr, Hf and Lu measurements for a variety of ocean island basalts determined by isotope dilution MC-ICPMS together with Hf isotope compositions are presented to constrain OIB source characteristics and HFSE fractionation during mantle melting and crystal fractionation.

Revised effective ionic radii and systematic studies of interatomic distances in halides and chalcogenides
TL;DR: The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations as mentioned in this paper.

Chromian spinel as a petrogenetic indicator in abyssal and alpine-type peridotites and spatially associated lavas
Henry J. B. Dick,Thomas Bullen +1 more
TL;DR: The composition of chromian spinels in alpine-type peridotites has a large reciprocal range of Cr and Al, with increasing Cr# (Cr/(Cr+Al)) reflecting increasing degrees of partial melting in the mantle as mentioned in this paper.
