Gibbs Free Energy of Formation of Zircon from Measurement of Solubility in H2O
TL;DR: In this article, the Gibbs free energy of formation of zircon (ZrSiO 4 ) was determined at 800°C, 1.2 GPa, by weight loss of synthetic Zircon crystals.
Diopside, enstatite and forsterite solubilities in H2O and H2O-NaCl solutions at lower crustal and upper mantle conditions
Catherine A. Macris,Catherine A. Macris,Robert C. Newton,Jeremy Wykes,Ruiguang Pan,Craig E. Manning +5 more
TL;DR: In this article, the authors determined experimentally the solubilities of diopside, enstatite and forsterite in H2O-NaCl fluids at a range of pressures and temperatures, and showed that saltbearing brines have substantial metasomatic power and may exert significant control on the chemical evolution of lower crustal and upper mantle mafic and ultramafic rocks.

- 01 Jan 1981
TL;DR: In this article, the authors propose a model of thermodynamic valables for the dissolution of clinopyroxenes, which is based on the thermodynamic model proposed by Mossbauer et al. In particular, the model is used for the diffusion of rayons X par des monocristaux.

Temperature, Pressure and Metamorphic Fluid Regimes in the Amphibolite Facies to Granulite Facies Transition Zones
Robert C. Newton
- 01 Jan 1985
TL;DR: In this paper, high activities of F, CO2 and SO2 were recorded in fluorbiotite and scapolite and water activities were 0.35 and lower, based on calculations of orthopyroxene stability, fluid inclusions, and volatiles in cordierite.

The Composition of Low-Pressure Synthetic Sapphirine
F. C. Bishop,Robert C. Newton +1 more
TL;DR: In this paper, a synthetic sapphirine prepared by sintering oxide mixes at high temperatures and 1 atm has been micro-analyzed, which yielded compositions in weight percent averaging MgO, 20.0; A1₂O, 68.1; and SiO, 11.9 with small scatter.
