(2001)Coesite has been found as a relic in ultrahigh pressure metamorphic (UHPM) crust worldwide and is expected to play a major role in the mechanical behavior of continental crust at UHPM conditions. We performed triaxial ...
-
(2006)Experiments characterizing the kinetics of anorthosite dissolution in lunar picritic magmas (very low-Ti, low-Ti, and high-Ti picritic glasses) were conducted at 0.6 GPa and 1250-1400 °C using the dissolution couple method. ...
-
(2002)Extreme enrichment in H2O, B, P and F is characteristic of many evolved granites and pegmatites. We report experimental phase relations of a synthetic peraluminous pegmatite spiked with P2O5, B2O3 and F (5 wt% of each), ...
-
(2003)To assess the effect of the melt composition on bromine concentrations in magmas, we have investigated bromide solubility for water-saturated, iron-free silicic melts with variable Na+K/Al and Si/Al molar ratios (albite, ...
-
(1999)Ca-(Fe,Mg) interdiffusion experiments between natural single crystals of grossular (Ca2.74Mg0.15 Fe0.23Al1.76Cr0.04Si3.05O12) and almandine (Ca0.21Mg0.40 Fe2.23Mn0.13Al2.00Cr0.08Si2.99O12 or Ca0.43Mg0.36Fe2.11 Al1.95Si3.04O12), ...
-
(1998)Dissolution rates of single calcite crystals, limestones, and compressed calcite powders were determined from sample weight loss using free-drift rotating disk techniques. Experiments were performed in aqueous HCl solutions ...
-
(2002)Dissolution rates of single calcite crystals were determined from sample weight loss using free-drift rotating disk techniques. Experiments were performed at 25 °C in aqueous HCl solutions over the bulk solution pH range ...
-
(2001)The transport of copper is affected by complexing with ligands such as chloride, bisulphide and acetate. Many copper deposits are formed from hydrothermal waters and brines and in order to understand their formation we ...
-
(1999)Steady-state dissolution rates of Haute Vallee de l'Aude dolomite were measured in mixed-flow reactors using rotating disk techniques. Experiments were performed in aqueous HCl solutions over the bulk solution pH range ...
-
(2002)Mineral-melt partition coefficients of vanadium and a series of divalent trace elements (Ni, Co, Mn, Sr) have been determined for ferrobasaltic bulk compositions at one atmosphere. Experiments were performed at constant ...
-
(2001)Steady state enstatite dissolution rates, at far from equilibrium conditions, were measured as a function of aqueous magnesium and silica activity, pH from 1 to 11, and temperature from 28°C to 168°C. All rates were measured ...
-
AN EXPERIMENTAL STUDY OF FE-AL SOLUBILITY IN THE SYSTEM CORUNDUM-HEMATITE UP TO 40 KBAR AND 1300°C (2005)The mutual solubility in the system corundum–hematite [[α-(Al, Fe3+)2O3] was investigated experimentally using both synthetic and natural materials. Mixtures of γ-Al2O3 and α-Fe2O3 (weight ratios of 8:2 and 10:1) were used ...
-
(2001)Steady state forsterite dissolution rates, at far from equilibrium conditions and pH=2+/-0.04, were measured as a function of aqueous magnesium and silica concentrations, and temperatures from 25°C to 65°C. All rates were ...
-
(2002)Creation of pathways for melt to migrate from its source is the necessary first step for transport of magma to the upper crust. To test the role of different dehydration-melting reactions in the development of permeability ...
-
(2003)Dissolution rates of natural illite (Illite du Puy) were measured from Si release rates during closed system experiments at pH ranging from 1.4 to 12.4 and temperatures ranging from 5 to 50°C. Experiments performed at ...

(1998)The Gibbs free energy (Delta G 0 (sub (1)) ) of the reaction kaolinite dickite was generated from solubility measurements of natural kaolinite and dickite performed in acid solutions at temperatures ranging from 150 to ...
-
(1997)Steady-state dissolution and precipitation rates of a pure highly crystalline kaolinite were determined as a function of chemical affinity and aqueous Si and Al concentrations using a mixed flow reactor at 150°C, 40 bars, ...
-
(1993)Kr diffusivity and solubility have been measured in glasses of SiO2, NaAlSi3O8, KAlSi3O8 and rhyolitic composition, under experimental conditions ranging from 700° to 950°C and 215 to 3150 bar. Kr diffusion in SiO2 (Sil) ...
-
(2000)Vitrinite reflectance is a parameter widely used to determine the extent of thermal maturation in sedimentary basins. Laboratory heating experiments were conducted to examine the role of aqueous fluid and sediment composition, ...
