-
(2003)In this study, sensitivities of 10 land-surface schemes (LSS) to five prescribed model parameters (i.e. the maximum soil moisture content (MSMC), effective available water content (EAWC), Clapp-Hornberger B parameter, leaf ...
-
(1995)Experiments were performed to investigate the interconnectivity of sodium carbonate melt in a synthetic dunite at low melt fractions at 1 GPa and 1300° C. Carbonate melt was found to remain interconnected to 0.05 wt% melt ...
-
(2004)Interdiffusion coefficients have been determined for H2O-CO2 mixtures by quantifying the flux of CO2 between two fluid-filled chambers in a specially designed piston-cylinder cell. The two chambers, which are maintained ...
-
(2002)Interfacial energies of quartz/quartz (qz/qz), albite/albite (ab/ab), and quartz/albite (qz/ab) boundaries in low-grade pelitic schist were determined based on measured values of dihedral angles. Three kinds of microstructures ...
-
(2005)We have measured the interfacial tension γSF between sulfide and silicate melts over the temperature range from 1250 to 1325 °C by in situ measurement of the shapes of sessile drops of sulfide immersed in silicate melt, ...
-
(2003)On basis of analysis of complex geological-geophysical information, the most characteristic aspects of tectonic-geodynamic transformations of Arctic region periphery at evolution stage of North Eurasia have been considered. ...
-
(2004)Claerbout's daylight imaging concept is generalized to a theory of interferometric seismic imaging (II). Interferometric seismic imaging is defined to be any algorithm that inverts correlated seismic data for the reflectivity ...
-
(2003)Comparison of the observed far-infrared (FIR) spectrum of Cl−-containing hydrotalcite, [Mg3Al(OH)8]Cl·3H2O, to a power spectrum calculated using molecular dynamics (MD) computer simulation, provides a greatly increased ...
-
(2004)It has been found that aspidolite, the Na analogue of phlogopite, has an unusual interlayer structure for micas. The aspidolite investigated is interleaved with phlogopite in a thermally metamorphosed rock. Electron ...
-
(2002)Phlogopitic micas of the solid solution binaries KMg3[AlSi3O10](OH)2 (phlogopite) RbMg3[AlSi3O10](OH)2 (Rb-phlogopite), phlogopite – CsMg3[AlSi3O10](OH)2 (Cs-phlogopite), and phlogopite – BaMg3[Al2Si2O10](OH)2 (kinoshitalite) ...
-
(1988)At present, oil and gas fields as well as numerous oil and gas shows have been found in the intermediate complexes of both young and old platforms. On the basis of lithologic and tectonic indicators, potential oil areas ...
-
(2000)The dehydration of goethite has been studied by low-temperature induced magnetization (LTIM) and X-ray diffraction on well-characterized acicular crystals. Fresh samples were heated in air to temperatures between 155°C and ...
-
(PANGAEA, 2013-04-22)The deep Black Sea is known to be depleted in electron-acceptors for sulphide oxidation. This study on depth distributions of sulphur species (S(II), S(0),S(n)**2-,S2O3**2-,SO3**2-,SO4**2-) in the Dvurechenskii mud volcano, ...
-
(2004)In this communication, we present a new method of earthquake prediction (algorithm M8S) that provides prediction for territories several times larger than the source of the predicted event and over a magnitude range of ...
-
(2010)Data from the literature were used to systematize intermediate-term (with advance times of 1 month to ~2.5 years) precursors to the M ≥ 6.6 Kamchatka earthquakes of 1987−2004. The precursors were observed as changes in ...
-
(2004)It has been proposed that large earthquakes (EQ) are similar to critical phenomena. A new method for the research of the critical fluctuations and for the estimation of corresponding critical exponents is applied to the ...
-
(2002)We present paleomagnetic results of Paleocene welded tuffs of the 53–50 Ma Bogopol Group from the northern region (46°N, 137°E) of the Sikhote Alin volcanic belt. Characteristic paleomagnetic directions with high unblocking ...
-
(1988)The chemical composition of haloignimbrite phases has not yet been adequately studied, so existing views on their origin are somewhat hypothetical. To investigate the nature of such phases, the authors used the Superprobe-733 ...
-
(1988)Hydrochemical methods are important in prospecting for deep-water sulfide ores in the ocean. Their efficient use and the development of techniques for interpreting the resultant data require a knowledge of the structure ...
