MULTICOMPONENT DIFFUSION AND CONVECTION IN MOLTEN MGO-AL2O3-SIO2 - III. INTERDIFFUSION COEFFICIENTS (1998)Multicomponent diffusion and convection in molten MgO-Al2O3-SiO2 at 1550°C and 0.5 GPa were examined experimentally in diffusion couples formed around 22.5 (wt%) MgO, 17.5% Al2O3, and 60% SiO2. The diffusion matrix obtained ...
-
(1995)Experimental results are presented for eighteen experiments exploring multicomponent chemical-diffusion in basaltic liquids. Experiments were performed in Columbia River Basalt (CRB) composition doped with about 5 wt% SiO2, ...
-
(1995)We have measured the multicomponent diffusion coefficient matrix, D, for silica rich melts in the system K2O-Al2O3-SiO2 between 1100-1600°C in air. Measurements were done in both peraluminous as well as peralkaline ...
-
(2005)This paper presents the results of studying Vendian rock samples collected along the middle coarse of the Dniester River in the Ukrainian territory. The results of their demagnetization revealed seven components of their ...
-
(2002)In this paper, we present the conception of the multidimensional self-affine distribution and show that the multidimensional self-affine distribution possesses the fractal property of scale-invariance under truncation, ...
-
(2001)In this article we propose an advanced technique for detecting low contrast geochemical anomalies using a set of features. There are three principal elements in this technique: (1) a statistical measure of the contrast of ...

(Pleiades Publishing, Ltd. (Плеадес Паблишинг, Лтд) (Род-Таун), 2004)The paper presents results of joint multidimensional wavelet analysis of three series of variations in the electrotelluric potential observed at the Verkhnyaya Paratunka station in the Kamchatka Peninsula from October 1, ...
-
(2000)In 1995-1998 the Kamchatkan Experimental Seismological Team (KEST), Geophysical Service (GS), Russian Academy of Sciences (RAN) conducted, in cooperation with other research and production organizations, organizational-technical ...
-
(1990)Investigation of the lateral distribution of seismicity has identified a self-similar hierarchical structure in the seismic field. In addition, it has been shown that the clustering of weak earthquake in plan is of predictive ...
-
(2002)This paper reports new data on petrology and geochemistry of gabbroids and quartz monzonites from the multiphase Phenai Mata Intrusive Complex (PMIC). The complex is situated in the northwest of the Deccan Trap Province ...
-
(2001)The Syrostan gabbro-granite pluton is situated immediately to the west of the Main Uralian Fault and exemplifies a multiple series of five intrusive rhythms. Each rhythm characterizes a separate episode of emplacement of ...
-
(2004)The Khaldzan Buregte group of alkaline massifs was formed during seven intrusive phases and is confined to a large dike belt within Early Caledonian island-arc ophiolite and normal granite cutting the ophiolite. The uranium ...
-
(2005)Sedimentary greigite (Fe3S4) is being increasingly implicated as the carrier of late diagenetic remagnetizations in fine-grained marine and terrestrial sediments. We have conducted detailed scanning electron microscope ...
-
(1988)Methane occurrences in the Earth's crust are predominantly of biogenic origin, i.e. their ultimate source is biologically formed organic matter. Methane can also form through inorganic reactions and is consequently termed ...
-
(2002)Low-temperature phase transitions of leonite-type compounds, K2Me2+(SO4)2 · 4H2O (Me = Mg, Mn, Fe), are investigated by temperature dependent measurements of single-crystal X-ray reflection intensities and lattice parameters. ...
-
(2000)The multiple-scales structure of mantle convection remains largely unknown. A 3D model of convection is used to investigate the effect of a viscosity step on the multiple-scales pattern of an infinite Prandtl number ...
-
(1995)Argon, Kr, and Xe were extracted from fluid inclusions (FI) in the Stripa granite by laser microprobe decrepitation of quartz and feldspar and measured in a low blank, high sensitivity, ion-counting mass spectrometer. Both ...
