Rare earth elements in hydrothermal systems: Estimates of standard partial molal thermodynamic properties of aqueous complexes of the rare earth elements at high pressures and temperatures
TL;DR: In this paper, the authors used predicted association constants for rare earth element (REE) complexes to calculate the speciation of the REEs in simulated and natural fluid compositions over ranges of pH, temperature, and pressure.

Hydrothermal Mobilisation of the Rare Earth Elements – a Tale of “Ceria” and “Yttria”
TL;DR: Although rare earth elements have been thought by many to be immobile in hydrothermal fluids, we have known since the first attempts to separate them in the early nineteenth century that they are soluble in aqueous solutions as mentioned in this paper.

Hydrothermal transport, deposition, and fractionation of the REE: experimental data and thermodynamic calculations
TL;DR: In this paper, the authors review a body of high-temperature experimental data collected over the past 15 years on the stability of REE aqueous species and minerals using this new thermodynamic dataset, and re-evaluate the mechanisms responsible for hydrothermal transport and deposition of the REE.

Magmatic-to-hydrothermal crystallization in the W–Sn mineralized Mole Granite (NSW, Australia): Part II: Evolving zircon and thorite trace element chemistry
TL;DR: In this paper, the authors used laser-ablation inductively-coupled-plasma mass-spectrometric microanalysis with the aim of relating the chemistry of zircon to its growth environment.

Large partition coefficients for trace elements in high-silica rhyolites
Gail A. Mahood,Wes Hildreth +1 more
TL;DR: In this paper, the partitioning of 25 trace elements between high-silica rhyolitic glass and unzoned phenocrysts of potassic and sodic sanidine, biotite, augite, ferrohedenbergite, hypersthene, fayalite, titanomagnetite, ilmenite, zircon, and allanite has been determined by INAA on suites of samples from the mildly peralkaline lavas and tuff of the Sierra La Primavera, Mexico, and the metaluminous, compo

The aqueous geochemistry of the rare-earth elements and yttrium: 2. Theoretical predictions of speciation in hydrothermal solutions to 350°C at saturation water vapor pressure
TL;DR: In this article, the stability constants for trivalent REE complexes were predicted up to 350°C at saturated water vapor pressure using Helgeson's electrostatic approach combined with the isocoulombic approach and available experimental thermodynamic data at low temperatures.

Experimental studies of pegmatite genesis; l, A model for the derivation and crystallization of granitic pegmatites
TL;DR: In this paper, the genesis of granitic igneous pegmatites is considered in terms of a model conceived from results of field and laboratory studies and subsequently tested by means of experimental investigations, emphasizing the roles of water (and/or other relatively volatile substances), both as a dissolved constituent in granitic magmas and as the dominant constituent of a separate fluid phase that is in the supercritical state under most conditions of pegmatite formation.
