Controls on the fractionation of isovalent trace elements in magmatic and aqueous systems: evidence from Y/Ho, Zr/Hf, and lanthanide tetrad effect
TL;DR: In this paper, the authors investigated the properties of trace elements in aqueous systems and showed that trace element fractionation is not solely dependent on ionic charge and radius, but is also controlled by the electron configuration and the type of complexing ligand, since the latter two determine the character of the chemical bonding in the various complexes.

Mineral-aqueous fluid partitioning of trace elements at 900°C and 2.0 GPa: Constraints on the trace element chemistry of mantle and deep crustal fluids
TL;DR: In this paper, the authors measured mineral-aqueous fluid partition coefficients (Dmin/fluid) for U, Th, Pb, Nb, Ba, and Sr in experiments at 2.0 GPa and 900°C.
Journal ArticleDOI
SIMS determination of trace element partition coefficients between garnet, clinopyroxene and hydrous basaltic liquids at 2–7.5 GPa and 1080–1200°C
TL;DR: In this article, the authors used SIMS analysis of seven garnets, four clinopyroxenes, one orthopyroxene and one phlogopite crystallized from an undoped basanite and a lightly doped (200 ppm Nb, Ta and Hf) quartz tholeiite.
Journal ArticleDOI
New clinopyroxene-liquid thermobarometers for mafic, evolved, and volatile-bearing lava compositions, with applications to lavas from Tibet and the Snake River Plain, Idaho
TL;DR: In this article, the authors proposed a new model based on jadeite crystallization and diopside + hedenbergite exchange equilibria to calculate the depths and temperatures at which magmas partially crystallize.
Journal ArticleDOI
Experimental determination of partition coefficients for rare earth and high-field-strength elements between clinopyroxene, garnet, and basaltic melt at high pressures
TL;DR: In this article, the authors derived a set of partition coefficients for high-field strength elements (HFSE) and rare earth elements (REE) in a systematic, linked set of experiments at P and T conditions relevant to basalt petrogenesis.

TL;DR: In this paper, a number of experiments have been conducted in order to study the equilibria between olivine and basaltic liquids and to try and understand the conditions under which OIVINE will crystallize.

Melting in the oceanic upper mantle: An ion microprobe study of diopsides in abyssal peridotites
TL;DR: In this article, a systematic study of rare earth and other trace elements in discrete diopsides from residual abyssal peridotites sampled from 5000 km of ocean ridge demonstrates that they are the residues of variable degrees of melting in the garnet and spinel peridotsite fields.

Melting of a dry peridotite KLB‐1 up to 14 GPa: Implications on the Origin of peridotitic upper mantle
TL;DR: In this paper, a diapiric model was proposed for the genesis of komatiite magma by partial melting of mantle peridotite at 150-200 km depth.
