-
(1990)The phases of a stratified fluid, each concentrating different components of the original mixture, that constituted the initial fluid, may evolve separately in the course of subsequent flow through porous media, in accordance ...
-
(1988)The oxidizability of molybdenite was evaluated from the chemical potentials of the independent components, i.e., molybdenum and sulfur, at various stages of the oxidation process. The overall character of the dependence ...

USE OF CLAY MINERALS IN RECONSTRUCTING GEOLOGICAL PROCESSES: RECENT ADVANCES AND SOME PERSPECTIVES (1999)This article reviews that clay literature from the last ten years, which is devoted to the applications of clay minerals in the interpretation of geological processes in sedimentary basins. The results, selected by the ...
-
(1987)The authors cluster analysis to rank the ten most important oxides occurring in rocks and minerals (SiO2, TiO2, Al2O3, Fe2O3, FeO, CaO, MgO, Na2O, K2O, and H2O+) in order (from 1 to 10). The first is the oxide with the ...
-
(2003)We advance the method of Hudson and Priest (Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts 20 (1983) 73-89) to develop a method for a curved scanline to be used to predict the numbers of fractures ...
-
(1990)In the present paper we describe a method of using multiband satellite photographic data, obtained by the Kosmos satellites, for the trophic classification of lake systems. The best results were obtained from double-negative ...
-
(2001)Conservative tracers are necessary to obtain groundwater transport velocities at the field scale. Deuterated water is an effective tracer for this purpose due to its similarity to water, chemical stability, non-reactivity, ...
-
(2002)This paper describes the development and application of new mathematical models for estimation of well productivity during drainage of methane gob gas associated with coal extraction. It is established that the relationship ...
-
(2003)Estimation of soil water content in the root zone with time in different parts of a watershed is important for both strategic and tactical management of water resources, as well as of agricultural production, water quality, ...
-
(1989)Analysis of available geological and geophysical data indicates that slow convective flows occur in certain regions in the mantle. Many investigators have studied the structure of such flows, but the measurements cannot ...
-
(2003)The multifractal characteristics of seismic waveforms that have propagated through fractured media were studied using numerical experiments. The study suggests that multifractal waveform parameters (i.e. information ...
-
(1997)Addition of a simple evacuated collection device to nickel-tube pyrolysis bombs permits collection of the hydrogen gas produced during decomposition of water and other substances containing hydrogen. Tests using water ...
-
(1988)This article shows Raman spectra of water in the liquid (a) and solid (b) states. There are considerable differences between these spectra. We have made a detailed study of the alteration of the spectra when water crystallizes, ...
-
(2002)A passive sampling system for use with rhodamine WT (RWT) in groundwater tracing experiments was developed to assist in the characterisation of groundwater flow paths. Amberlite XAD-7 resin was found to be suitable for ...
-
(1987)The possibility of using seismoacoustic data to study the postsedimentational alteration of marine sediments is of interest both in the theory of lithogenesis and in practical problems associated with efficient utilization ...
-
(1997)A nuclear microbeam technique called elastic recoil detection analysis (ERDA) or forward recoil spectroscopy which is capable of yielding bulk H in silicates at ppm sensitivities is described. This technique is nondestructive ...
-
(2002)A new method has been developed to orient 50-100 μm size single crystals to obtain XANES or EXAFS spectra along any crystallographic orientation relative to a polarized synchrotron X-ray beam. The method uses a modified ...
-
(1989)In order to understand the role of volatiles in the phase transition from crystal to melt, it is very important to know not only the total concentration of fluid in the system, but also its distribution. The authors performed ...
-
(PANGAEA, 2013-04-26)High-latitude ecosystems play an important role in the global carbon cycle and in regulating the climate system and are presently undergoing rapid environmental change. Accurate land cover data sets are required to both ...
-
(2003)A new approach to estimating of shear-wave attenuation is proposed. The method is based on an assumption that an anisotropic attenuating geological medium possesses gyrotropic properties. Doing so allows to obtain attenuation ...
