(1999)The solubility of hematite, Fe2O3 (cr, α) in acidic (0.5 < pH < 2) and alkalic (12.7 < pH < 13.4) aqueous perchlorate solutions with ionic strengths of I = 0.1 and 0.316 was measured at 200°C and vapor saturation pressure. ...
-
(2006)The solubility of volatile compounds in magmas and the redox state of their mantle source are the main factors that control the transfer of volatile components from the planet's interior to its surface. In theories of the ...
-
(2004)The solubility of hydrogen in Mg-Fe olivines as a function of temperature and iron concentration was investigated by hydrothermally annealing single crystals of synthetic forsterite and San Carlos olivine. Experiments were ...
-
(1998)The solubility of KFe(CrO4)2·2H2O, a precipitate recently identified in a Cr(VI)-contaminated soil, was studied in dissolution and precipitation experiments. Ten dissolution experiments were conducted at 4–75°C and initial ...
-
(2005)The solubility of metallic mercury in dodecane, octane and toluene has been investigated experimentally at temperatures up to 200°C and pressures up to 6 bars (toluene). The equilibrium Hg concentrations are very similar ...
-
(1998)We determined solubility of Ne, Ar, Kr, and Xe in binary silicate melts (Na2O-SiO2 and MgO-SiO2) and ternary silicate melts (Na2O-CaO-SiO2 and CaO-MgO-SiO2) at total pressures of 1.10-1.99 kbars and temperatures of ...
-
(2002)Experimental data are presented for the solubility of NaNbO3 in the ternary system CaCO3-Ca(OH)2-NaNbO3 (or calcite-portlandite-lueshite) over the temperature range 500-950 °C at 0.1 GPa pressure. Near-liquidus phase ...
-
(2003)Hildebrand solubility parameters, δ, have been calculated for the most common petroleum compounds, thus establishing a relative solubility scale of petroleum compounds in kerogen. The scale predicts that aromatics as a ...
-
(2001)Platinum has been found to be mobile under supergene conditions, including placers and weathering profiles. To elucidate the nature of Pt mobility in supergene environments, the dissolution of platinum metal was investigated ...
-
(1997)Within the framework of Pitzer's specific interaction model, interaction parameters for aqueous silica in concentrated electrolyte solutions have been derived from Marshall and co-authors amorphous silica solubility ...
-
(2001)Silicon solubility in liquid Fe-rich metal was measured experimentally as a function of pressure, temperature and oxygen fugacity to determine if silicon could be a major light element in the Earth's core. At the P, T, fO2 ...
-
(2003)The solubility of the high grade pelite assemblage albite+K-feldspar+andalusite+quartz at 650 °C and 2 kbar was determined in aqueous solutions over a total chloride range of 0.01-3 mClt°t using rapid-quench hydrothermal ...
-
(1996)The solubility of tungsten (W) in a haplobasaltic melt has been determined as a function of oxygen fugacity in the temperature range 1300-1500oC using the mechanically assisted equilibrium technique of Dingwell et al. ...
-
(2006)Published solubility data for amorphous ferric arsenate and scorodite have been reevaluated using the geochemical code PHREEQC with a modified thermodynamic database for the arsenic species. Solubility product calculations ...
-
(1999)CO2 solubility and speciation in melts along the NaAlO2-SiO2 join from Ne (NaAlSiO4) to a model rhyolite (Ry) composition (NaAlSi6O14), have been investigated as a function of pressure (10 to 25 kb) and temperature (1450 ...
-
(2001)Trace metals associate with Fe(III) oxides as adsorbed or coprecipitated species, and consequently, the biogeochemical cycles of iron and the trace metals are closely linked. This communication investigated the solubilization ...
-
(1997)The solute and particulate contents of organic materials, lipids, and aliphatic and polycyclic aromatic hydrocarbons (PAHs) in surface and near-bottom waters are measured in the Bay of Sakhalin in the areas of the Astrakhan ...
-
(2006)Understanding the effects of climate change including precipitation patterns has important implications for evaluating the biogeochemical responses of watersheds. We focused on four storms in late summer and early fall ...

SOLUTE TRANSPORT IN A SINGLE FRACTURE WITH NEGLIGIBLE MATRIX PERMEABILITY: 1. FUNDAMENTAL MECHANISMS (2003)This report describes the fracture-scale mechanisms acting on solute transport in fractured aquifers under natural-flow conditions. It focuses on low-permeability rocks where advection in the matrix is negligible compared ...

SOLUTE TRANSPORT IN A SINGLE FRACTURE WITH NEGLIGIBLE MATRIX PERMEABILITY: 2. MATHEMATICAL FORMALISM (2003)This report provides an overview of the mathematical expressions for modeling fundamental solute transport mechanisms at the fracture scale. It focuses on low-permeability rocks where advection in the matrix is negligible ...
