-
(1998)The pH of fluids at elevated temperature-pressure conditions are routinely calculated from fluid compositions measured in the laboratory. Numerical errors, uncertainties in thermodynamic data, and analytical errors can ...
-
(1996)Based on direct geophysical measurements and theoretical calculations a new approach was developed to the prediction of maximum seismic ground motion in areas with disturbed permafrost soils. This approach was implemented ...
-
(2002)Characterization of soil hydraulic behavior at large scales using traditional methods is time-consuming and very costly. Efficient and cheap means of providing hydrological models with such information are procedures based ...
-
(2005)Quantitative characterization of the development of proton surface charge on the surfaces of minerals is necessary for a fundamental understanding of reactions between minerals and aqueous electrolyte solutions. Despite ...
-
(1990)The frequency of occurrence of shocks within a zone depends upon the rate of tectonic movements and the dimensions of the foci. In some zones, shocks occur in various segments of the zone at intervals of tens of years; in ...
-
(1990)The earthquake discussed occurred in Tajikistan, along the southern boundary of the Gissar Valley. In 1980, I have emphasized that in detailed, large-scale seismic zoning for the purpose of planning earthquake-resistant ...
-
(1988)To interpret the diffusional processes that bring about correlated change in the chemistry of coexisting olivines and chrome spinels, one can use the model of a semiinfinite composite sphere or the novel method of kinetic ...
-
(2001)The hydration free energies of water at two state points (2344 K and 1.0 g/cm3, and 2000 K and 1.8 g/cm3) were calculated using the ABC-FEP method (Wood et al., 1999) that combines interaction energies calculated from ab ...
-
(2002)Uplift, erosion and removal of overburden have profound effects on sedimentary basins and the hydrocarbon systems they contain. These effects are predictable from theory and from observation of explored exhumed basins. ...
-
(2006)The phase state of hydrocarbon accumulations was predicted using recent drilling data for three oil and gas complexes of the northern regions of the West Siberian petroliferous basin: Lower and Middle Jurassic, Upper ...
-
(2006)Despite the fact that the bulk compositions of most low temperature natural surface waters, groundwaters, and porewaters are heavily influenced by alkaline earths, an understanding of the development of proton surface ...
-
(1990)The dehydration of gypsum CaSO4·H2O and the crystal structure of the resulting compounds have often been investigated. But the published data on the temperature intervals in which the various phases can exist in the ...
-
(1997)A large number of aqueous metal complexes contribute significantly to hydrothermal, metamorphic, and magmatic processes in the crust of the Earth. Nevertheless, relatively few thermodynamic data other than dissociation ...
-
(2003)The distribution of solutes between coexisting liquid and vapor phases of water can be expressed by the distribution constant, KD, defined as where y and x stand for the mole fraction concentrations of a solute in vapor ...
-
(2001)Trace metal partitioning between authigenic minerals and aqueous solutions is of great interest to both geochemical and environmental communities. In this paper, we have developed a linear free energy correlation model ...
-
(2003)Hydrates in marine sediments are estimated to contain more methane than conventional reserves. Previous estimates of the amounts of methane hydrate ignore pore size effects and variations in hydrate saturation of the pore ...
-
(2006)Predictions of catchment hydrology have been performed generally using either physically based, distributed models or conceptual lumped or semi-distributed models. In recognition of the disadvantages of using either of ...
-
(2000)In this study, a functional group additivity scheme was used for correlation of the partial molar volumes, V 0 , 2 compressibilities, k 0 , heat capacities, C 0 , hydration enthalpies, D H 0 , and hydration Gibbs energies, ...
-
(2006)Potassium-rich halite ores and brines occur in the Charham Salt Lake area in the Chaidam Basin in northwest China. The mean 14.3 g/l of potassium in the brines in the near-surface halite aquifer makes the Charham Salt Lake ...
-
(2001)Marine Cretaceous sequences of the eastern margin of northeast Asia show remarkable predominance of terrestrial woody kerogens over marine algal ones. Microscopic study on 18 hemipelagic mudstones collected from three dated ...
