(2001)Proceeding from the concept of the significant role of mixing of abyssal (magmatic) and meteoric fluids in the formation of tungsten ores in granite-related hydrothermal systems, the influence of the dilution of ore-forming ...
-
(2001)H2O, CO2, CH4, CO, H2 and O2 are the most important species in crustal fluids. The composition of these C-O-H fluids can be calculated if the pressure, temperature, carbon activity, and either the oxygen fugacity or the ...
-
(2000)Experimental work in the ternary system NaCl–NaBr–H2O at 25°C and 1 atm was carried out to determine the distribution of Br in halite and to close gaps in former sets of data. In order to model the incorporation of Br, a ...

(2002)The reaction muscovite+cordierite→biotite+Al2SiO5 +quartz+H2O is of considerable importance in the low pressure metamorphism of pelitic rocks: (1) its operation is implied in the widespread assemblage Ms + Crd +And± Sil + ...
-
(2004)Cratonic mantle eclogite xenoliths occur with diamond-bearing kimberlite. The modes and mineral compositions of eclogite contain important information on their origin, physical-chemical conditions of formation, and their ...
-
(2003)This publication is an attempt to systematically apply numerical simulations to investigations into cosmochemical and planetological systems. The approaches formulated during the development of stable techniques of numerical ...
-
(2004)We present modifications to a previously reported statistical thermodynamics model that facilitates the prediction of capillary pressure effects on hydrate equilibria in narrow pores. The model uses the Valderrama modification ...
-
(1996)The infrared and Raman spectra of CaCO3 calcite substituted with 80% 18O have been recorded. A detailed mode assignment is proposed for all the observed bands, including combinations and overtones. These data are used to ...
-
(2002)Calorimetric and experimental data on AlF-bearing titanite are presented that yield thermodynamic properties of CaAlFSiO4, as well as activity-composition relations of binary titanite CaTiOSiO4–CaAlFSiO4. The heat capacity ...

THERMODYNAMIC PROPERTIES AND STOICHIOMETRY OF AS(III) HYDROXIDE COMPLEXES AT HYDROTHERMAL CONDITIONS (1996)The stoichiometry and thermodynamic properties of As(III) hydroxide complexes were determined from both solubility and Raman spectroscopic measurements. Arsenolite, claudetite, and orpiment solubilities were measured at ...
-
(1998)The stoichiometry and thermodynamic properties of Ge(IV) hydroxide complexes were generated from both solubility and potentiometric measurements. The solubility of the tetrahedral germanium oxide (GeO2(tetr)) was measured ...

-
(1997)Experimental solubilities reported in the literature for magnetite, hematite, pyrite, and pyrrhotite over wide ranges of pressure and temperature have been combined with experimental dissociation constants for aqueous ...
-
(2001)The thermodynamic properties of natural stilbite and stellerite were determined by the methods of high-temperature Calvet calorimetry. The standard enthalpies of formation from oxides and elements are -232.0 ± 8.3 and -11 ...
-
(2004)Heat capacity of SnO2(c) is measured by adiabatic calorimetry at 13.40-336.88 K. Using these data we calculated the values of heat capacity, entropy, and enthalpy increment for T = 0-336 K and P = 1 bar. These thermodynamic ...
-
(1997)The standard molal thermodynamic properties of α-GaOOH at temperatures to 700 K were retrieved from (1) low-temperature α-GaOOH heat capacity measurements, (2) solubility measurements of α-GaOOH and β-Ga2O3, and (3) data ...
-
(1990)A solution model is developed for rhombohedral oxide solid solutions having compositions within the ternary system ilmenite [(Fe 2+ s Ti 4+ 1–s ) A (Fe 2+ 1–s Ti 4+ s ) B O3]-geikielite [(Mg 2+ t Ti 4+ 1–t ) A (Mg 2+ 1–t ...

THERMODYNAMIC PROPERTIES OF HERCYNITE (FEAL2O4) BASED ON ADIABATIC CALORIMETRY AT LOW TEMPERATURES (2003)The low-temperature heat capacity of hercynite (FeAl2O4) was measured between 3 and 400 K. and thermochemical functions were derived from the results. The measured heat-capacity curve shows a small lambda-shaped anomaly ...
